Akl EA; Gaddam S; Gunukula SK; Honeine R; Abou Jaoude P; Irani J. The effects of waterpipe tobacco smoking on health outcomes: A systematic review. (review). International Journal of Epidemiology 39(3): 834-857, 2010. (52 refs.)

Methods: We conducted a systematic review using the Cochrane Collaboration methodology for conducting systematic reviews. We rated the quality of evidence for each outcome using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Results: Twenty-four studies were eligible for this review. Based on the available evidence, waterpipe tobacco smoking was significantly associated with lung cancer [odds ratio (OR) = 2.12; 95% confidence interval (CI) 1.32-3.42], respiratory illness (OR = 2.3; 95% CI 1.1-5.1), low birth-weight (OR = 2.12; 95% CI 1.08-4.18) and periodontal disease (OR = 3-5). It was not significantly associated with bladder cancer (OR = 0.8; 95% CI 0.2-4.0), nasopharyngeal cancer (OR = 0.49; 95% CI 0.20-1.23), oesophageal cancer (OR = 1.85; 95% CI 0.95-3.58), oral dysplasia (OR = 8.33; 95% CI 0.78-9.47) or infertility (OR = 2.5; 95% CI 1.0-6.3) but the CIs did not exclude important associations. Smoking waterpipe in groups was not significantly associated with hepatitis C infection (OR = 0.98; 95% CI 0.80-1.21). The quality of evidence for the different outcomes varied from very low to low. Conclusion: Waterpipe tobacco smoking is possibly associated with a number of deleterious health outcomes. There is a need for high-quality studies to identify and quantify with confidence all the health effects of this form of smoking.

Arora M; Schwarz E; Sivaneswaran S; Banks E. Cigarette smoking and tooth loss in a cohort of older Australians: The 45 and Up Study. Journal of the American Dental Association 141(10): 1242-1249, 2010 , 2010. (35 refs.)

Background. Data regarding the long-term effects of smoking, smoking cessation and environmental tobacco smoke (ETS) on tooth loss are limited. Methods. The authors collected information about tooth loss and other health-related characteristics from a questionnaire administered to 103,042 participants in the 45 and Up Study conducted in New South Wales, Australia. The authors used logistic regression analyses to determine associations of cigarette smoking history and ETS with edentulism, and they adjusted for age, sex, income and education. Results. Current and former smokers had significantly higher odds of experiencing edentulism compared with never smokers (prevalence odds ratio [OR] 2.51; 95 percent confidence interval [CI] 2.31-2.73 and OR, 1.50; 95 percent CI, 1.43-1.58, respectively). Among former smokers, the risk declined significantly with increasing time since smoking cessation; however, the risk remained elevated even in those who ceased smoking 30 or more years previously compared with that in never smokers (OR, 1.10; 95 percent CI, 1.02-1.19). Furthermore, among never smokers, the OR for edentulism was 1.37 (95 percent CI, 1.17-1.60) in those who reported having exposure to ETS for six or more hours per week versus those who were not exposed to any ETS. Conclusions and Clinical Implications. Although the risk of experiencing tooth loss declines with time since smoking cessation, the effects of smoking may persist for at least 30 years. The effect of ETS requires further investigation.

Bayat E; Bauss O. Effect of smoking on the failure fates of Oothodontic miniscrews. Journal of Orofacial Orthopedics 71(2): 117-124, 2010. (28 refs.)

Objective: The aim of this study was to investigate the effect of cigarette smoking on the failure rates of orthodontic miniscrews. Patients and Methods: Our cohort consisted of 88 patients with a total of 110 orthodontic miniscrews. Based on their smoking habits, the patients were divided into three groups: the Light smokers (<= 10 cigarettes/day), heavy smokers (> 10 cigarettes/day), and non-smokers. The light-smoker group consisted of 14 patients with 18 orthodontic miniscrews, and there were 15 patients with 19 miniscrews among the heavy smokers. The nonsmoker group contained 59 patients with a total of 73 miniscrews. Results: The overall failure rate was 18.2% (n = 20). Heavy smokers revealed a significantly higher failure rate than light smokers (p = 0.005) or non-smokers (p < 0.001). No significant differences were observed between non-smokers and light smokers. Miniscrews in the heavy smoker group exhibited a significantly higher failure rate during the first 4 months after insertion than did the miniscrews in the light smokers (p = 0.008) or non-smokers (p < 0.001). Conclusion: Our results suggest that heavy smoking has a detrimental effect on the success rates of orthodontic miniscrews.

Clareboets S; Sivarajasingam V; Chestnutt IG. Smoking cessation advice: Knowledge, attitude and practice among clinical dental students. British Dental Journal 208(4): 173-177, 2010. (39 refs.)

Objective To examine knowledge, attitude and current practice among clinical dental students in giving smoking cessation advice (SCA) and to explore the barriers to this activity. Design and setting A self-administered questionnaire survey of clinical dental students at Cardiff University School of Dentistry. Materials and methods In 2008, clinical dental students were surveyed (n = 181). Information on smoking cessation practices, students' attitude, potential barriers and level of preparedness to deliver SCA, knowledge of association between tobacco use and various pathological conditions and demographics and tobacco use by clinical dental students were gathered. Results One hundred and sixty-one (89%) students responded. All students enquired about patient smoking habits in the previous three months but were inconsistent in providing SCA - only one third of students gave SCA all or nearly all the time. Students had good knowledge of the associated health risks with tobacco use. A majority of students perceived barriers in providing patients with SCA. Those who provided advice were more likely to have positive attitudes and reported feeling adequately prepared. Conclusions Dental educators should address students' perceived barriers towards providing SCA when designing smoking cessation curricula in order to produce dentists who are confident and competent to provide this important health care intervention.

Crail J; Lahtinen A; Beck-Mannagetta J; Benzian H; Enmark B; Jenner T et al. Role and models for compensation of tobacco use prevention and cessation by oral health professionals. International Dental Journal 60(1): 73-79, 2010. (10 refs.)

Appropriate compensation of tobacco use prevention and cessation (TUPAC) would give oral health professionals better incentives to provide TUPAC, which is considered part of their professional and ethical responsibility and improves quality of care. Barriers for compensation are that tobacco addiction is not recognised as a chronic disease but rather as a behavioural disorder or merely as a risk factor for other diseases. TUPAC-related compensation should be available to oral health professionals, be in appropriate relation to other dental therapeutic interventions and should not be funded from existing oral health care budgets alone. We recommend modifying existing treatment and billing codes or creating new codes for TUPAC. Furthermore, we suggest a four-staged model for TUPAC compensation. Stages 1 and 2 are basic care, stage 3 is intermediate care and stage 4 is advanced care. Proceeding from stage 1 to other stages may happen immediately or over many years. Stage 1: Identification and documentation of tobacco use is part of each patient's medical history and included into oral examination with no extra compensation. Stage 2: Brief intervention consists of a motivational interview and providing information about existing support. This stage should be coded/reimbursed as a short preventive intervention similar to other advice for oral care. Stage 3: Intermediate care consists of a motivational interview, assessment of tobacco dependency, informing about possible support and pharmacotherapy, if appropriate. This stage should be coded as preventive intervention similar to an oral hygiene instruction. Stage 4: Advanced care. Treatment codes should be created for advanced interventions by oral health professionals with adequate qualification. Interventions should follow established guidelines and use the most cost-effective approaches.

Davis JM; Koerber A. Assessment of tobacco dependence curricula in U.S. dental hygiene programs. Journal of Dental Education 74(10): 1066-1073, 2010 , 2010. (38 refs.)

Tobacco dependence education (TDE) continues to be a vital component of dental hygiene curricula made even more important by the fact that tobacco cessation in adults in the United States has stagnated over the past ten years. This study was undertaken to assess the salient characteristics of TDE in U.S. dental hygiene programs. A fifty-one question survey was mailed to the program directors of all 283 accredited dental hygiene programs during the 2007-08 school year (this number does not include the programs in Illinois, which were excluded since they had participated in a previous study). A total of 187 schools returned the survey for a return rate of 66 percent. Curricular content, minutes spent on each topic, existing level of clinical competence measured, expected level of clinical competence, and resources used were assessed. Researchpondents reported an average of 6.7 hours spent on all identified components of tobacco education. While 77 percent of respondents reported formally assessing whether a student asked if a patient used tobacco, only 26 percent indicated having a formal competency utilizing all of the U.S. Public Health Service's Clinical Practice Guideline 5 As and 5 Rs. In contrast, 72 percent of program directors reported expecting their graduates to be competent in a moderate intervention that included all 5 As. Though there is a clear commitment to TDE among dental hygiene programs in the United States, we recommend training to a more intensive level of TDE in order to facilitate broader adoption of comprehensive, evidence-based guidelines.

Davis JM; Ramseier CA; Mattheos N; Schoonheim-Klein M; Compton S; Al-Hazmi N et al. Education of tobacco use prevention and cessation for dental professionals - a paradigm shift. International Dental Journal 60(1): 60-72, 2010. (88 refs.)

The use of tobacco continues to be a substantial risk factor in the development and progression of oral cancer, periodontitis, implant failure and poor wound healing. Dental and dental hygiene education providers have made great advances towards the incorporation of tobacco education into their curricula in recent years. Unfortunately, however, both medical and dental education research has consistently reported schools providing only basic knowledge-based curricula that rarely incorporate more effective, behaviourally-based components affecting long-term change. The limited training of oral healthcare students, at least in part, is reflected in practising dental professionals continuing to report offering incomplete tobacco interventions. In order to prepare the next generation of oral healthcare providers, this paper proposes a paradigm shift in how tobacco use prevention and cessation (TUPAC) may be incorporated into existing curricula. It is suggested that schools should carefully consider: to what level of competency should TUPAC be trained in dental and dental hygiene schools; the importance of establishing rapport through good communication skills; the core knowledge level for TUPAC; suggested instructional and assessment strategies; the importance of continuing professional education for the enhancement of TUPAC.

Davis JM; Stockdale MS; Cropper M. Evaluation of a comprehensive tobacco cessation curriculum for dental hygiene programs. Journal of Dental Education 74(5): 472-479, 2010 , 2010. (29 refs.)

Dental health care providers continue to offer inconsistent and limited tobacco use cessation (TUC) interventions even though smoking-related morbidity and mortality continue to be a substantial health concern. Our purpose was to conduct a comprehensive, three-year (2003-06) TUC curriculum evaluation that included assessment of existing TUC education offered; dental hygiene educators' readiness to incorporate TUC education into the curriculum; and development of a pre-test/post-test assessment instrument and faculty development program. This curriculum study was carried out alongside a research study to evaluate the effectiveness of a peer-reviewed tobacco curriculum (Tobacco Free! Curriculum). Faculty members (baseline n=97; third-year n=42) from the twelve dental hygiene associate degree programs in Illinois participated in the study, which included a pre-treatment survey, six hours of on-site TUC curriculum training, and a post-treatment survey to determine the attitudes, perceived barriers, and current practices in tobacco education. Results showed an average increase of eighty-five minutes spent on tobacco education in the dental hygiene curriculum, a large positive increase in the percentage of faculty members who formally assessed the use of 5As and 5Rs (21 percent to 88 percent), and a dramatic increase (+100) in the percentage of faculty members who taught or included most of the thirteen TUC content areas following the introduction of the curriculum and training program.

Dukic W; Dobrijevic TT; Katunaric M; Milardovic S; Segovic S. Erosive lesions in patients with alcoholism. Journal of the American Dental Association 141(12): 1452-1458, 2010. (70 refs.)

Background: The authors conducted a study to determine the occurrence of erosive tooth lesions in patients with alcoholism and to establish the influence of salivary flow rates and pH levels on their appearance Methods: The authors conducted a cross sectional study in 140 participants (70 with clinically diagnosed alcoholism who were undergoing therapy for their addiction were in the test group and 70 who did not consume alcohol were in the control group) The authors determined the participants salivary statuses by measuring the flow rates and pH levels of both unstimulated and stimulated saliva Results: The authors found more erosive lesions in the test group (P < 01) They detected a higher number of erosive lesions in participants in the test group who had a pH range of 5 to 6 compared with a pH range of 6 to 7 (P = 01) They found a significant correlation between alcoholism and unstimulated salivary flow rate (P < 05) Conclusions: The salivary flow rate was similar in control and test groups The prevalence of erosion in the test group was higher than that in the control group which may be related to the decrease in salivary pH of both stimulated and unstimulated saliva in this group The results of the study showed no connection between erosion prevalence and pH levels and stimulated salivary flow rates Clinical Implications Patients with alcoholism may be at risk of developing erosive lesions on their teeth owing to the low pH level of their oral environment and decreased saliva levels

Gallagher JE; Alajbeg I; Buchler S; Carrassi A; Hovius M; Jacobs A et al. Public health aspects of tobacco control revisited. International Dental Journal 60(1): 31-49, 2010. (74 refs.)

The tobacco epidemic presents a major public health challenge, globally, and within Europe. The aim of the Public Health Work Stream at the 2nd European Workshop on Tobacco Use Prevention and Cessation for Oral Health Professionals was to review the public health aspects of tobacco control and make recommendations for action. The paper reports on the size of the tobacco challenge; from the associated mortality and morbidity to the prevalence of exposure to, and use of, tobacco. It provides a review of progress on tobacco control measures, as monitored by the World Health Organisation, and the impact of multiple influences on tobacco use. Every member of the dental team was considered to have a role as a public health advocate in promoting health and preventing disease in order to address health inequalities. A range of evidence-based approaches to tobacco control from clinical practice through to public policy are advocated, using the principles of the Ottawa Charter, recognising the multiple determinants of health. Tackling the tobacco epidemic may require a paradigm shift in oral healthcare. Therefore, key resources for health professionals on tobacco control are discussed and the implications of the findings for research, policy and practice in Europe are explored.

Gonseth S; Abarca M; Madrid C; Cornuz J. A pilot study combining individual-based smoking cessation counseling, pharmacotherapy, and dental hygiene intervention. BMC Public Health 10: article 348, 2010. (29 refs.)

Background: Dentists are in a unique position to advise smokers to quit by providing effective counseling on the various aspects of tobacco-induced diseases. The present study assessed the feasibility and acceptability of integrating dentists in a medical smoking cessation intervention. Methods: Smokers willing to quit underwent an 8-week smoking cessation intervention combining individual-based counseling and nicotine replacement therapy and/or bupropion, provided by a general internist. In addition, a dentist performed a dental exam, followed by an oral hygiene treatment and gave information about chronic effects of smoking on oral health. Outcomes were acceptability, global satisfaction of the dentist's intervention, and smoking abstinence at 6-month. Results: 39 adult smokers were included, and 27 (69%) completed the study. Global acceptability of the dental intervention was very high (94% yes, 6% mostly yes). Annoyances at the dental exam were described as acceptable by participants (61% yes, 23% mostly yes, 6%, mostly no, 10% no). Participants provided very positive qualitative comments about the dentist counseling, the oral exam, and the resulting motivational effect, emphasizing the feeling of oral cleanliness and health that encouraged smoking abstinence. At the end of the intervention (week 8), 17 (44%) participants reported smoking abstinence. After 6 months, 6 (15%, 95% CI 3.5 to 27.2) reported a confirmed continuous smoking abstinence. Discussion: We explored a new multi-disciplinary approach to smoking cessation, which included medical and dental interventions. Despite the small sample size and non-controlled study design, the observed rate was similar to that found in standard medical care. In terms of acceptability and feasibility, our results support further investigations in this field.

Gordon JS; Andrews JA; Crews KM; Payne TJ; Severson HH; Lichtenstein E. Do faxed quitline referrals add value to dental office-based tobacco-use cessation interventions? Journal of The American Dental Association 141(8): 1000-1007, 2010 , 2010. (24 refs.)

Background. The Ask, Advise, Refer (AAR) model of intervening with patients who use tobacco promotes a brief office-based intervention plus referral to a tobacco quitline. However, there is little evidence that this model is effective. The primary aim of this study was to evaluate the effects on patients' tobacco use of two levels of a dental office-based intervention compared with usual care. Methods. The, authors randomly assigned 68 private dental clinics to one of three conditions: 5 As (Ask, Advise, Assess, Assist, Arrange); 3 As (AAR model); or usual care, and they enrolled 2,160 participants. Results. At the 12-month assessment, compared with those in usual care, participants in the two intervention conditions combined were more likely to report cessation of tobacco use, as measured by nine-month prolonged abstinence (3 percent versus 2 percent; F-1,F-66 = 3.97, P < .10) and 12-month point prevalence (12 percent versus 8 percent; F-1,F-66 = 7.32, P < .01). There were no significant differences between participants in the clinics using the 5 As and 3 As strategies. Conclusions. The results of this study are inconclusive as to whether referrals to a quitline add value to brief dental office based interventions. Patients receiving telephone counseling quit tobacco use at higher rates, but only a small percentage of those proactively referred actually received counseling. Clinical Implications. The results confirm those of previous research: that training dental practitioners to provide brief tobacco-use cessation advice and assistance results in a change in their behavior, and that these practitioners are effective in helping their patients to quit using tobacco.

Gordon JS; Andrews JA; Albert DA; Crews KM; Payne TJ; Severson HH. Tobacco cessation via public dental clinics: Results of a randomized trial. American Journal of Public Health 100(7): 1307-1312, 2010. (15 refs.)

Objectives. We sought to compare the effectiveness of a dental practitioner advice and brief counseling intervention to quit tobacco use versus usual care for patients in community health centers on tobacco cessation, reduction in tobacco use, number of quit attempts, and change in readiness to quit. Methods. We randomized 14 federally funded community health center dental clinics that serve diverse racial/ethnic groups in 3 states (Mississippi, New York, and Oregon) to the intervention (brief advice and assistance, including nicotine replacement therapy) or usual care group. Results. We enrolled 2549 smokers. Participants in the intervention group reported significantly higher abstinence rates at the 7.5-month follow-up, for both point prevalence (F-1,F-12=6.84;P<.05) and prolonged abstinence (F-1,F-12=14.62; P<.01) than did those in the usual care group. Conclusions. The results of our study suggest the viability and effectiveness of tobacco cessation services delivered to low-income smokers via their dental health care practitioner in community health centers. Tobacco cessation services delivered in public dental clinics have the potential to improve the health and well-being of millions of Americans.

Han DH; Lim SY; Sun BC; Paek D; Kim HD. The association of metabolic syndrome with periodontal disease is confounded by age and smoking in a Korean population: the Shiwha-Banwol Environmental Health Study. Journal of Clinical Peridontology 37(7): 609-616, 2010. (42 refs.)

Aim: Because metabolic syndrome (MS) is pro-inflammatory and periodontitis is inflammatory, we issued the hypothesis that MS (the explanatory variable) is associated with periodontitis (the outcome variable). This study aimed to examine the link between MS and periodontitis among Koreans. Materials and Methods: From the Shiwha-Banwol Environmental Health Study, 1046 subjects aged 18 years or older were cross-sectionally surveyed. All participants underwent comprehensive dental and medical health examinations. The community periodontal index was used to assess periodontitis. Age, gender, monthly family income, smoking, drinking, frequency of daily teeth brushing, and physical activity were evaluated as confounders. Results: MS was strongly associated with periodontitis [odds ratio (OR): 1.7, 95% confidence interval (CI): 1.22-2.37], and MS with more components had a higher association. The association was higher for elders aged 65 years or more, males, and smokers. MS including both high glucose and hypertension had a higher association with the OR of 2.19 (95% CI: 1.23-3.90) comparing with other types of MS. Conclusions: Our results suggested that MS might be associated with periodontitis and the association was confounded by age, gender, and smoking. MS with high glucose and hypertension showed the higher impact on this link.

Hedman E; Riis U; Gabre P. The impact of behavioural interventions on young people's attitudes toward tobacco use26. Oral Health & Preventive Dentistry 8(1): 23-32, 2010 , 2010. (26 refs.)

Purpose: The objective of the present study was to study the ability to influence young at-risk patients attitudes toward tobacco use through two intervention methods that were performed by dental health professionals. Materials and Methods: Two inteiventions, a brief individual motivational interview and an adapted school lecture, were studied, and both were compared with a control group. Before and after interventions, a questionnaire was used. Patients born in 1989 and 1992 who were judged by the dental personnel as potentially at risk for dental diseases, a total of 301 individuals, were included. Results: Both before and after interventions, the results showed a generally negative attitude towards tobacco use. A majority of the participants were positive towards measures that were taken to control the spread of tobacco use, younger participants (born 1992) to a greater extent (73%) than the older participants (born 1989) (54%) Important factors that kept the participants away from tobacco use were the harmful effects and the approaches of parents and friends. The older participants believed to a greater extent that they would try smoking as adults. No change in tobacco use was registered after intervention, although the participants reported an increased use among friends. Conclusions: The two pedagogical methods that were used in the present study influenced the young people's attitudes towards tobacco use only to a small extent. However, the period between 12 and 15 years old seems to provide a good opportunity to influence attitudes towards tobacco. The adolescents' demand for interactive learning and their development of attitudes and tobacco use habits in relation to family and friends provide opportunities to use new pedagogical models.

Jamieson LM; Gunthorpe W; Cairney SJ; Sayers SM; Roberts-Thomson KF; Slade GD. Substance use and periodontal disease among Australian Aboriginal young adults. Addiction 105(4): 719-726, 2010. (27 refs.)

Aim: To investigate the effects of tobacco, marijuana, alcohol and petrol sniffing on periodontal disease among Australian Aboriginal young adults. Design: Cross-sectional nested within a long-standing prospective longitudinal study. Setting: Aboriginal communities in Australia's Northern Territory. Participants: Members of the Aboriginal Birth Cohort study who were recruited from birth between January 1987 and March 1990 at the Royal Darwin Hospital, Northern Territory, Australia. Data were from wave III, when the mean age of participants was 18 years. Measurements: Clinical dental examination and self-report questionnaire. Findings: Of 425 participants with complete data, 26.6% had moderate/severe periodontal disease. There was elevated risk of periodontal disease associated with tobacco [prevalence ratio (PR) = 1.59, 95% CI = 1.06-2.40], marijuana (PR = 1.44, 95% CI = 1.05-1.97) and petrol sniffing (PR = 1.83, 95% CI = 1.08-3.11), but not alcohol (PR = 0.92, 95% CI = 0.67-1.27). Stratified analysis showed that the effect of marijuana persisted among tobacco users (PR = 1.47, 95% CI 1.03-2.11). It was not possible to isolate an independent effect of petrol sniffing because all petrol sniffers used both marijuana and tobacco, although among smokers of both substances, petrol sniffing was associated with an 11.8% increased prevalence of periodontal disease. Conclusions: This is the first time that substance use has been linked with periodontal disease in a young Australian Aboriginal adult population, and the first time that petrol sniffing has been linked with periodontal disease in any population. The role of substance use in periodontal disease among this, and other, marginalized groups warrants further investigation.

Kapferer I; Berger K; Stuerz K; Beier US. Self-reported complications with lip and tongue piercing. Quintessence International 41(9): 731-737, 2010 , 2010. (20 refs.)

Objectives: Owing to the overwhelming popularity of oral piercing, general practitioners should be prepared to address complications arising as a result of oral piercing and to provide patients with accurate information. The purpose of this cross-sectional study was to assess the prevalence of early and late complications associated with lip and tongue piercing in a population obtained from a nondental setting. Possible cofactors were evaluated. Method and Materials: The study cohort included 130 lip and 80 tongue piercings. Participants were asked to complete a questionnaire to determine demographic data, smoking habits, characteristics of the piercing worn (time since piercing, material-plastic or metal), postpiercing complications, and possible cofactors. Results: Prevalence of early piercing complications was 87.83%. Although there was no statistically significant difference in the overall prevalence of early postpiercing complications after lip or tongue piercing, the type of complication differed significantly according to the piercing location. Significant cofactors for early complications were oral hygiene behavior, gender, and the person who performed the piercing. The highest prevalence of late complications was found to be recurrent infections and gingival recessions. As cofactors, time since piercing and oral hygiene behavior had a significant impact on late complications. Conclusion: Early complications after oral piercing are frequent. Oral health care might be an important tool to minimize early and late postpiercing complications. Owing to the high prevalence of late complications-especially after median lip piercing-persons with oral piercing should attend regular dental checks and receive professional advice on tooth cleaning and oral hygiene.

Khami MR; Murtomaa H; Razeghi S; Virtanen JI. Smoking and its determinants among Iranian dental students. Medical Principles and Practice 19(5): 390-394, 2010 , 2010. (25 refs.)

Objective: The objective of the present study was to investigate smoking habits of Iranian dental students in relation to their background characteristics and oral self-care (OSC). Subjects and Methods: A survey in the form of a questionnaire was conducted of 327 senior dental students in seven randomly selected state dental schools in Iran. In addition to smoking habits and background characteristics, the students were asked about OSC. A recommended level of OSC was defined as a combination of brushing at least twice a day, frequent use of fluoridated toothpaste, and eating sugary snacks less than daily. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). A total of 263 students (113 males and 150 females) completely answered the questions and were included in the analyses. Results: Of the 263 students, 59 (23%, 37 males and 22 females) reported current smoking (cigarette, pipe, or water pipe). Current smoking was associated with male gender (OR = 2.9, 95% CI = 1.4-5.6), level of father's education (OR = 1.4, 95% CI = 1.1-1.8), and OSC (OR = 4.4, 95% CI = 1.3-14.9). Conclusion: Smoking among Iranian dental students is similar to their socioeconomic group, and is associated with the characteristics of their background, such as gender and father's level of education, as well as the quality of OSC. The results indicate a need to include smoking cessation education and public health activities in the dental curriculum to provide future health care professionals and role models for patients with adequate training in up-to-date patient management to control smoking.

Liu SW; Lien MH; Fenske NA. The effects of alcohol and drug abuse on the skin. Clinics in Dermatology 28(4): 391-399, 2010. (89 refs.)

Skin changes associated with alcohol and drug abuse can be the earliest clinical manifestation of these disorders. The signs associated with these conditions may be distinctive and easily recognizable. Alcohol abuse can present with jaundice, pruritus, hyperpigmentation, and urticaria. Commonly associated vascular changes include spider telangiectasias, angiomas, caput medusas, flushing, and palmar erythema. Disease states related to alcohol abuse include psoriasis, porphyria cutanea tarda, and nutritional deficiencies. Alcohol abuse may predispose to the development of carcinomas of the skin, oropharynx, liver, pancreas, and breast. Cutaneous signs of drug abuse include skin granulomas, ulcerations, and recurrent infections. Specifically, oral disease and tooth decay are examples of stigmata often associated with methamphetamine abuse, a popular and inexpensive drug now on the scene. By being cognizant of these cutaneous markers of alcohol and drug abuse, dermatologists are often in the unique position of being able to recognize these changes, prompting early diagnosis and intervention, hopefully resulting in a better clinical outcome for these troubled patients and their families.

McClellan SF; Olde BA; Freeman DH; Mann WF; Rotruck JR. Smokeless tobacco use among military flight personnel: A survey of 543 aviators. Aviation, Space, and Environmental Medicine 81(6): 575-580, 2010. (20 refs.)

Introduction: Although there has been a steady decline in smoking rates among adults in the United States in recent years, the consumption of smokeless tobacco (ST) continues to increase. Moreover, ST use in the U.S. military is far higher than in the general population. This study was designed to determine the extent of ST use in a military aviation population and measure users' attitudes toward elements of a proposed cessation program. Methods: A study was conducted at two naval aviation training wings in western Florida. The target population (N = 2233) included flight instructors, students, and staff/support personnel who were rated aviators or flight officers. A total of 543 usable questionnaires were returned, yielding a response rate of 24.3%. Results: There were 71 respondents who reported using ST in the last 30 d (13.1%). This group responded favorably to questions regarding the involvement of both medical and dental health professionals as critical components of an effective ST cessation program. Discussion: This survey provides evidence for a rate of ST use among military aviators that is much higher than the U.S. national civilian average of 3.5%. Drawing upon the background of previous dental health-based studies, we propose augmenting existing tobacco cessation resources by creating separate ST cessation programs to reduce ST use among U.S. military aviators.

Purpose: The aim of the present study was to assess the periodontal condition and smoking status, according to dose and duration information, and to estimate the percentage of subjects with periodontitis attributable to cigarette smoking in a representative adult rural population in southern Brazil. Materials and Methods: Bivariate statistical analysis was used to evaluate the association of smoking status with periodontitis in a cross-sectional study comprising 165 dentate individuals, aged 35 to 66 years, subjected to oral clinical examination of six sites per tooth in all sextants. Results: The prevalence of periodontitis (having >= 1 pocket of >= 4 mm around the index teeth) in the population was 35.2%. Overall, 13.9% had a cumulative loss of attachment > 4 mm; 35.7% of subjects were current smokers, classified as heavy (average 25.3 pack years), moderate (average 14.6 pack years) and light smokers (average 3.1 pack years). Statistical analysis showed that current smokers had an 11 times (95% confidence interval [Cl] = 4.69 to 26.62) and former smokers had a nine times (95% CI = 3.29 to 25.96) greater probability of having established periodontitis compared with non-smokers. The number of pack years (P = 0.0004) and years of smoking exposure (P = 0.0013) were associated with an increased prevalence of periodontitis. The number of current smokers with periodontitis might be reduced by 80%, had they not smoked cigarettes. Of the subjects with periodontitis, 64% could be prevented among current smokers by eliminating tobacco consumption. Conclusions: Cigarette smoking was strongly associated with periodontitis, and there was a relationship with dose and duration of smoking. These findings contributed to the evidence of smoking as a risk factor for periodontal disease and support the importance of dose-response analysis on determining the strength of this association.

Needleman IG; Binnie VI; Ainamo A; Carr AB; Fundak A; Koeber A et al. Improving the effectiveness of tobacco use cessation (TUC). International Dental Journal 60(1): 50-59, 2010. (59 refs.)

This paper includes an update of a Cochrane systematic review on tobacco use cessation (TUC) in dental settings as well as narrative reviews of possible approaches to TUC and a more detailed discussion of referral for specialist TUC services. On the basis of these reviews we conclude that interventions for tobacco users in the dental setting increase the odds of quitting tobacco. However, the evidence is derived largely from patients using smokeless tobacco. Pharmacotherapy (such as nicotine replacements, bupropion and varenicline) is recommended for TUC in medical settings but has received little assessment in dental applications, although such evidence to date is promising. Whether the dental setting or referral to specialist TUC services is the most effective strategy to help people to quit tobacco use is unclear. An effective specialist service providing best available TUC care alone may not be the answer. Clearly, such services should be both accessible and convenient for tobacco users. Closer integration of specialist services with referrers would also be advantageous in order to guide and support oral health professionals make their referral and to maximise follow-up of referred tobacco users. Future research direction may consider investigating the most effective components of TUC in the dental settings and community-based trials should be a priority. Pharmacotherapy, particularly nicotine replacement therapy, should be more widely examined in dental settings. We also recommend that various models of referral to external and competent in-house TUC specialist services should be examined with both experimental and qualitative approaches. In addition to overall success of TUC, important research questions include facilitators and barriers to TUC in dental settings, preferences for specialist referral, and experiences of tobacco users attempting to quit, with dental professionals or specialist services, respectively.

Analyses of the 2002 U.S. National Health and Examination Survey (1,490 adults) examined relationships between alcohol frequency, quantity, and total weekly consumption and preventive and emergency dental service use during the past 12 months. Logistic regression analyses indicated a significant, small percentage of variance in dental service use explained by alcohol use (1%), controlling for predisposing (19%), enabling (18%), or need (4%) covariates. Preventive and emergency service use were associated with higher frequency drinking, but lower total consumption (significant only for preventive services). Limitations and implications for brief alcohol interventions in dental practice are discussed.

Purpose: Tobacco use screening and brief intervention is recognised as an effective available preventive health service; yet, this service is still not routinely offered to dental patients by clinicians, despite dental schools generally providing some form of tobacco cessation counselling (TCC) by including it in their dental curriculum. A pilot study was therefore carried out to more clearly identify barriers that prevented the delivery of this service to tobacco-using patients at the University of Pittsburgh School of Dental Medicine and educational initiatives that might overcome these barriers. Materials and Methods: A survey of faculty and students asked participants to rank their knowledge, preparation and comfort levels in performing TCC as well as their belief as to the importance of such training in the dental curriculum. Six months following training and practice opportunities, surveys were again administered to participants. Each individual's pre- and post-TCC training surveys were reviewed and difference in response to each item was calculated. Results: The results of the present study show that students feel more prepared, that the time required to provide TCC was less than anticipated and that training in TCC is an important part of dental education to a greater extent after the pilot study than before. Conclusions: TCC training and practice opportunities for clinical application were effective in this pilot study in improving students' attitudes towards cited barriers.

Park YD; Patton LL; Kim JH; Kim HY. Smoking prevalence and attitude toward anti-smoking activities among Korean dentists. International Dental Journal 60(6): 383-388, 2010. (34 refs.)

Aims: To investigate the smoking habits and attitudes toward anti-smoking activities of Korean dentists according to their smoking status. Methods: A questionnaire was mailed to a random sample of 2,500 currently active Korean dentists in 2008. After 20% of the 1,680 returned surveys (response rate 67.2%) were excluded due to missing data, 1,443 surveys were analysed. Results: Among the 1,443 respondents, most were male (81.8%) and age 40-49 was the most prevalent age group (41.6%). Approximately half of participating dentists were never-smokers, 24.6% were current smokers, and 29% were ex-smokers. Women (95.8%) were significantly more likely to have never smoked than men (35.4%). Prevalence of cigarette smoking of Korean male and female dentists was much lower than that of male and female Korean adults, respectively. Ex-smokers were significantly more likely to show a positive attitude about anti-smoking activities, compared to current smokers (p<.0001). Conclusions: A majority of respondents agreed dentists should encourage their patients to stop smoking. Further effort is needed to encourage smoking cessation among male Korean dentists who smoke so they benefit from a healthier lifestyle and will subsequently be more likely to provide recommendations for smoking prevention and cessation for their patients.

In order to facilitate effective tobacco cessation services within dental school clinics, it is necessary to understand the perceived barriers encountered by dental students while providing these services. The aim of this study was to identify which factors fourth-year dental students perceive to be associated with barriers to providing tobacco intervention services. A written survey was developed and completed by incoming fourth-year dental students (a convenience sample of seventy students) at the University of Iowa College of Dentistry in 2008. The survey assessed the perceived barriers to providing tobacco intervention services and related factors. Descriptive, bivariate, and linear regression analyses were conducted. The response rate was 97 percent. The most frequently reported barriers were patients' resistance to tobacco intervention services (96 percent), inadequate time available for tobacco intervention services (96 percent), and forgetting to give tobacco intervention advice (91 percent). The following variables were significantly (p<0.05) related to greater perceived barriers in providing tobacco intervention services: lower "adequacy of tobacco intervention curriculum coverage of specific topics covered over the previous three years" and greater "perceived importance of incorporating objective structured clinical examination teaching method for learning tobacco intervention." Students probably could benefit from additional didactic training, but most important may be enhanced clinical experiences and faculty reinforcement to facilitate effective practical student learning and adaptation for future delivery of intervention services in private practice settings.

Introduction: Higher levels of smoking, leading to increased levels of nicotine and dopamine release, may be more strongly related to bruxism, although this relationship has remained unclear. Thus, the aim of the present study was to investigate the possible effect of cumulative tobacco use on bruxism in a large sample of young adults. Methods: The material of the present study derives from the FinnTwin16, which consists of five birth cohorts born in 1975-1979. A total of 3,124 subjects (mean age 24 years, range 23-27 years) provided data in 2000-2002 on frequency of bruxism and tobacco use. Multinomial logistic regression was used to explore the relationships of frequency of bruxism with smoking and smokeless tobacco use while controlling covariates (alcohol intoxication, alcohol problems [Rutgers Alcohol Problem Index, RAPI], illicit drug use, psychological distress [General Health Questionnaire], and coffee use). Results: Based on subjective response and multivariate analyses, weekly bruxers were more than two times more likely to report heavy smoking than never bruxers (odds ratio [OR] 2.5, 95 % CI 1.8-3.4). The significant association between heavy smoking and bruxism held when the effects of other tobacco use and multiple covariates were controlled. In addition, the use of smokeless tobacco emerged as an independent risk factor for bruxism. Discussion: Given the observed associations with both heavy smoking and smokeless tobacco and a dose-response relationship, the present results support our hypothesis of a link between nicotine intake and bruxism.

Few existing studies have examined health and oral health needs and treatment-seeking behavior among the homeless and injection drug users (IDUs). This paper describes the prevalence and correlates of health and oral health care needs and treatment-seeking behaviors in homeless IDUs recruited in San Francisco, California, from 2003 to 2005 (N=340). We examined sociodemographic characteristics, drug use patterns, HIV status via oral fluid testing, physical health using the Short Form 12 Physical Component Score, self reported needs for physical and oral health care and the self-reported frequency of seeking medical and oral health care. The sample had a lower health status as compared to the general population and reported a frequent need for physical and oral health care In bivariate analysis, being in methadone treatment was associated with care-seeking behavior In addition, being enrolled in Medi Cal California's state Medicaid program, was associated with greater odds of seeking physical and oral health care. Methamphetamine use was not associated with higher odds of needing oral health care as compared to people who reported using other illicit drugs. Homeless IDUs in San Francisco have a large burden of unmet health and oral health needs. Recent cuts in Medi Cal's adult dental coverage may result in a greater burden of oral health care which will need to be provided by emergency departments and neighborhood dental clinics

Objective: Smoking influences oral health in several ways (such as the occurrence of periodontitis, teeth discolouration and oral cancer); therefore, smoking behaviour should be addressed in dental care. Dentists can play a role in primary and secondary prevention of tobacco dependence. They see their patients repeatedly over time. This study investigates whether oral health complaints can be seized as an opportunity to start smoking cessation counselling. Methods: A structured patient questionnaire in a sample of 1101 smokers (52.1% women, mean age 40.4 years) in a convenience sample of 87 primary care dental practices. The I-change model was used to describe factors influencing behavioural change. Dependent factors such as intention to quit smoking and related factors (attitude, social support and self-efficacy) were analysed in relation to independent factors such as oral health complaints (gingiva problems, gingiva inflammation, oral cancer and discoloured teeth) using a general linear model (univariate analysis), multinomial logistic regression analysis and multiple linear regression analysis. Results: A total of 56.3% had discoloured teeth, 27% of the smokers had a problem with their gums and 15.7% had gingiva inflammation. We found no direct relation between oral health complaints and the intention to quit smoking. However, teeth discolouration was positively related to attitudes towards smoking cessation [beta, Confidential interval (95%); 1.92 (1.45-2.40 for advantages and -0.86(-1.18 to -0.53) for disadvantages] and negatively to self-efficacy regarding quitting [-2.69 (-3.49 to 1.88)]. Conclusions: We found no direct relation between oral health complaints and the intention to quit smoking, but oral health complaints and especially teeth discolouration were related to factors influencing the quit intention. Patients with discoloured teeth are more likely to have a positive attitude towards smoking cessation but are uncertain to persist smoking cessation. It is suggested that teeth discolouration can be a good entrance for addressing smoking cessation in daily dental practice.

Introduction: Smoking by health care professionals poses a barrier to interventions with patients. This study reports smoking status changes among health care professionals using the Tobacco Use Supplement-Current Population Surveys (TUS-CPS). Methods: TUS-CPS self-reported smoking status (current, former, and never) identified by occupation (physicians, physician assistants, registered nurses [RNs], licensed practical nurses [LPNs], respiratory therapists, dentists, and dental hygienists), were analyzed for the 2003 (N = 4,095) and 2006/2007 (N = 3,976) cohorts. Quit ratios among U. S. health care professionals were calculated by dividing the number of former smokers by the number of ever-smokers using weighted estimates. Results: In 2006/2007, LPNs (20.55%) and respiratory therapists (19.28%) had the highest smoking prevalence. Physicians (2.31%), dentists (3.01%), pharmacists (3.25%), and RNs (10.73%) had the lowest prevalence. Data from 2006/2007 indicate that physicians, pharmacists, dentists, and physician assistants had the highest quit ratios; all groups had quit ratios higher than the general public, except LPNs (. 52 vs. .46, respectively). Current smoking varied by group but did not significantly decline from 2003 to 2006/2007. The majority of health care professionals were never-smokers. Conclusions: These data indicate that only 4 health care professional groups met the Healthy People 2010 goal of 12% smoking prevalence. LPNs were the only group with quit ratios lower than the general population. The lack of significant decline in smoking rates among health professionals was similar to the "flat" rate seen among adults in the United States. This is of concern as smoking among health care professionals limits their interventions with smokers and their involvement in tobacco control.

Shepherd S; Young L; Clarkson JE; Bonetti D; Ogden GR. General dental practitioner views on providing alcohol related health advice: An exploratory study. British Dental Journal 208(7): e13, 2010. (36 refs.)

Objective To identify salient beliefs of general dental practitioners (GDPs) regarding their role in the identification of alcohol misuse and the provision of an alcohol related health message in the primary dental care setting. Method: A convenience sample of 12 GDPs practising in the North Highland region of Scotland underwent semi-structured interview. An inductive approach was used with subsequent basic thematic content analysis performed on the transcripts. Results GDPs universally agreed that alcohol consumption plays a role in both oral health and general health but this did not translate into effective communication about alcohol during dental consultation. Current knowledge of recommended safe alcohol consumption guidelines was poor - evidence of potential GDP training requirements. The primary barriers related to disruption of the clinician-patient relationship, embarrassment or the perceived irrelevance to the clinical situation. GDPs expressed low confidence in approaching alcohol related problems. Conclusions: GDPs felt that alcohol based discussions in primary care would not be relevant and would inevitably lead to disruption of the patient-clinician relationship. Further research is necessary to more fully understand the attitudes, behaviour and knowledge of GDPs regarding the provision of alcohol related health advice. The results of this study have informed the design of a paper postal survey for wider distribution.

Shetty V; Mooney LJ; Zigler CM; Belin TR; Murphy D; Rawson R. The relationship between methamphetamine use and increased dental disease. Journal of the American Dental Association 141(3): 307-318, 2010. (46 refs.)

Background. Methamphetamine (MA) use has been linked anecdotally to rampant dental disease. The authors sought to determine the relative prevalence of dental comorbidities in MA users, verify whether MA users have more quantifiable dental disease and report having more dental problems than nonusers and establish the influence of mode of MA administration on oral health outcomes. Methods. Participating physicians provided comprehensive medical and oral assessments for adults dependent on AM (n = 301). Trained interviewers collected patients' self-reports regarding oral health and substance-use behaviors. The authors used propensity score matching to create a matched comparison group of nonusers from participants in the the Third National Health and Nutrition Examination Survey (NHANES III). Results. Dental or oral disease was one of the most prevalent (41.3 percent) medical cormorbidities in MA users who otherwise were generally healthy. On average, MA users bad significantly more missing teeth than did matched NHANES Ill control participants (4.58 versus 1.96, P < .001) and were more likely to report having oral health problems (P < .001). Significant subsets of MA users expressed concerns with their dental appearance (28.6 percent), problems with broken or loose teeth (23.3 percent) and tooth grinding (bruxism) or erosion (22.3 percent). The intravenous use of MA was significantly more likely to be associated with missing teeth than was smoking MA (odds ratio = 2.47; 95 percent confidence interval = 1.3-4.8). Conclusions. Overt dental disease is one of the key distinguishing comorbidities in MA users. MA users have demonstrably higher rates of dental disease and report long-term unmet oral health needs. Contrary to common perception, users who smoke or inhale MA have lower rates of dental disease than do those who inject the drug. Many MA users are concerned with the cosmetic aspects of their dental disease, and these concerns could be used as behavioral triggers for targeted interventions. Clinical Implications. Dental disease may provide a temporally stable MA-specific medical marker with discriminant utility in identifying AM users. Dentists can play a crucial role in the early detection of MA use and participate in the collaborative care of AM users.

Shibly O. Effect of tobacco counseling by dental students on patient quitting rate. Journal of Dental Education 74(2): 140-148, 2010. (27 refs.)

Tobacco use has widespread, devastating effects on the body, including the oral cavity. Today's dental professional must be trained to counsel patients on tobacco cessation, but dental health professionals and students do not feel confident in their counseling, abilities. The University at Buffalo School of Dental Medicine (SDM) established the Tobacco Counseling Cessation Protocol (TCCP), which vas implemented in the dental curriculum, and dental Students were trained in its use. The goal of this project vas to assess the effectiveness of the TCCP by surveying both patients and dental students. Students and patients were contacted to determine the effect of the TCCP on the quitting rate. Third- and fourth-year dental students were surveyed through the school c-mail system and asked to report on their tobacco cessation counseling, practices. Patients who received TCCP received follow-up telephone calls to obtain their input on the program and also to determine if they had quit. According to the follow-up survey, 14 percent of patients reduced the number of cigarettes smoked per day, and 22 percent quit entirely. Fifty-one percent of those who received the TCCP made a commitment to quit at the lime of the intervention; 32 percent of those receiving the TCCP were still smoke-free at six months, but 19 Percent had returned to smoking. If predoctoral students receive appropriate training, they call he effective in motivating patients to quit smoking. Dental students are generally receptive to the educational material on tobacco use and smoking cessation counseling, yet only half report routinely implementing the TCCP More needs to be done to incorporate tobacco cessation counseling into routine dental care. The culture of dentistry must be changed to view tobacco use as a dental problem.

Tanaka K; Miyake Y; Arakawa M; Sasaki S; Ohya Y. Household smoking and dental caries in schoolchildren: The Ryukyus Child Health Study. BMC Public Health 10: article 335, 2010. (27 refs.)

Background: Secondhand smoke exposure (SHSe) is perhaps one of the most important toxic exposures in childhood. However, epidemiological studies on the relation between SHSe and dental caries are limited and have yielded inconsistent results. The present cross-sectional study examined the potential association between SHSe at home and the prevalence of dental caries in children. Methods: Subjects were 20,703 schoolchildren aged 6 to 15 years in Okinawa, Japan. Information on SHSe at home and potential confounding factors was obtained through questionnaires. Data on dental caries were obtained from school records. Children were classified as having decayed and/or filled teeth (DFT) if a dentist diagnosed these conditions. Additionally, we analyzed decayed teeth (DT) and filled teeth (FT) separately. Adjustment was made for sex, age, region of residence, toothbrushing frequency, use of fluoride, sugar intake, and paternal and maternal educational level. Results: The prevalence of DFT was 82.0%. Compared with never smoking in the household, former and current household smoking were independently associated with an increased prevalence of DFT (adjusted prevalence ratios [95% confidence intervals] for former household smoking and current light and heavy household smoking were 1.03 [1.00-1.05], 1.04 [1.02-1.05], and 1.04 [1.03-1.06], respectively); when analyzed separately there was an increased prevalence of DT (adjusted prevalence ratios [95% confidence intervals] for former household smoking and current light and heavy household smoking were 1.06 [1.02-1.11], 1.10 [1.06-1.13], and 1.10 [1.07-1.14], respectively) but not FT. A statistically significant dose-response relationship between cumulative smoking in the household and the prevalence of DFT and DT (P for trend < 0.0001), but not FT, was observed. In an analysis of 2 subgroups, subjects who had at least 1 deciduous tooth and subjects who had at least 1 permanent tooth, household smoking exposure was associated with an increased prevalence of DFT and DT not only in those with deciduous but also those with permanent dentition. Conclusion: Our findings suggested that household smoking might be associated with an increased prevalence of dental caries in children.

Tong EK; Strouse R; Hall J; Kovac M; Schroeder SA. National survey of US health professionals' smoking prevalence, cessation practices, and beliefs. Nicotine & Tobacco Research 12(7): 724-733, 2010. (35 refs.)

Tobacco dependence treatment efforts have focused on primary care physicians (PCPs), but evidence suggests that they are insufficient to help most smokers quit. Other health professionals also frequently encounter smokers, but their smoking prevalence, cessation practices, and beliefs are less well known. The study included 2,804 subjects from seven health professional groups: PCPs, emergency medicine physicians, psychiatrists, registered nurses, dentists, dental hygienists, and pharmacists. Outcomes included self-reported smoking status, smoking cessation practices, and beliefs. Multivariate regression was used to examine factors associated with health professionals (except pharmacists) self-reportedly performing the "5 A's": asking, advising, assessing, assisting, or arranging follow-up about tobacco. Health professionals have a low smoking prevalence (< 6%), except nurses (13%). Many health professionals report asking (87.3%-99.5%) and advising (65.6%-94.9%) about smoking but much less assessing smokers' interest (38.7%-84.8%), assisting (16.4%-63.7%), and arranging follow-up (1.3%-23.1%). Controlling for health professional and practice demographics, factors positively associated in the multivariate analyses with self-reportedly performing multiple components of the 5 A's include awareness of the Public Health Service guidelines, having had cessation training, and believing that treatment was an important professional responsibility. Negative associations include the health professional being a current smoker, not being a PCP, being uncomfortable asking patients if they smoke, believing counseling was not an appropriate service, and reporting competing priorities. U.S. health professionals report not fully performing the 5 A's. The common barriers and facilitators identified may help inform strategies for increasing the involvement of all health professionals in conducting tobacco dependence treatments.

Turp JC; Lunsch H; Radlanski RJ. Interdental spacing and orthodontic treatment in competitive athletes: Clues to doping with growth hormones? Journal of Orofacial Orthopedics 71(5): 373-382, 2010 , 2010. (24 refs.)

The aim of this report is to examine clues of a suspected link between the artificial ingestion of human growth hormone (rhGH) and resulting interdental spaces in adult athletes. We conducted an electronic search in the German-language versions of the search engines Google and Google Scholar as well as in the database PubMed. While no explicit articles could be identified in PubMed, the search in Google and Google Scholar produced 1370 and 6 hits, respectively. Original quotes from 20 sources show that in the media the wearing of orthodontic multibracket appliances among athletes is largely attributed to changes in tooth position as a consequence of the illegal ingestion of rhGH. On the other hand, there are few references to the possibility that orthodontic treatments with fixed appliances might be carried out for reasons unrelated to doping. Conclusion: A definitive assessment of this issue is not possible at present. In view of its major importance of the subject, the relationships depicted here should be investigated in greater depth.

Objective: To estimate the prevalence of tobacco, alcohol and drug use among dental undergraduates at one English university in 2008, and compare these with prevalence in 1998. Design Cross-sectional survey using an anonymous self-report questionnaire. Subjects and methods In 2008 all 384 dental undergraduates at one English university were sent a questionnaire in order to obtain data on the frequency and amount of tobacco, alcohol, cannabis and other illicit drugs used before and during their time as a dental undergraduate. The same survey had been conducted on dental undergraduates at the university 10 years earlier. Results: Tobacco smoking was reported by 27% of males and 13.5% of females, a reduction from 1998 (42% of males and 32% of females) being significant among females. 63% of males and 69.5% of females reported drinking alcohol: significantly fewer than in 1998 (82% males and 90% females). Binge drinking was reported by 69.5% of males compared to 56% in 1998. In females 66% binged compared to 58.5% in 1998. The increase in males was significant. 62% of males and 68% of females had never used cannabis compared to 38% in males and 50.5% of females in 1998, a significant reduction. A significant reduction in amphetamine use was reported among both male and female undergraduates in 2008 compared to 1998 and a significant increase in amyl nitrate use was reported by females. Reported illicit drug use was associated with alcohol drinking, and particularly with tobacco use. Conclusion Dental undergraduates at one English university in 2008 when compared to those in 1998 are reported to be significantly less likely to drink alcohol, use cannabis and amphetamines. If female, they are significantly less likely to smoke tobacco and overestimate the number of units of alcohol they can safely consume in a week, but more likely to use amyl nitrate. If male, those who drink alcohol are significantly less likely to drink at a level of increased risk, but more likely to binge drink.

Vered Y; Livny A; Zini A; Shabaita S; Sgan-Cohen HD. Dental students' attitudes and behavior toward smoking cessation as part of their professional education. Teaching and Learning In Medicine 22(4): 268-273, 2010 , 2010. (15 refs.)

Background: Dental professionals have a major role in promoting tobacco use cessation (TUC). Purpose: The objective is to assess dental students' knowledge, attitudes, behavior, and perception regarding their potential expected role. Methods: Self-administered anonymous questionnaires were used for all students of the Jerusalem Dental Medicine School. Results: Among 275 responding students, 17% reported smoking. Most students reported asking patients about smoking, counseling against smoking, and advising to quit. Only a minority reported providing antismoking educational material, suggesting nicotine replacements, and arranging follow-ups. Most students did not consider a list of suggested potential obstacles (lack of resources, not their role, etc.) as true barriers. Analysis by stage of studies by stage of studies revealed significant differences in reported TUC strategies and positive attitudes and decreases in perceived potential obstacles. Conclusions: These results indicate specific and practical areas for promoting antismoking intervention. Dental schools need to emphasize their role in preparing the next generation with a clear dedication toward TUC.

The purpose of this paper is to review the epidemiologic evidence for the effects of tobacco use and tobacco use cessation on a variety of oral diseases and conditions. Exposures considered include cigarette and bidi smoking, pipe and cigar smoking, and smokeless tobacco use. Oral diseases and disorders considered include oral cancer and precancer, periodontal disease, caries and tooth loss, gingival recession and other benign mucosal disorders as well as implant failure. Particular attention is given to the impact of tobacco use cessation on oral health outcomes. We conclude that robust epidemiologic evidence exists for adverse oral health effects of tobacco smoking and other types of tobacco use. In addition, there is compelling evidence to support significant benefits of tobacco use cessation with regard to various oral health outcomes. Substantial oral health benefits can be expected from abstention and successful smoking cessation in a variety of populations across all ages.

Wasilewski MDA; Takahashi MK; Kirsten GA; de Souza EM. Effect of cigarette smoke and whiskey on the color stability of dental composites. American Journal of Dentistry 23(1): 4-8, 2010. (33 refs.)

Purpose: To evaluate the effect of cigarette smoke and whiskey on the color stability of resin composites. Methods: Disk-shaped specimens (8 mm x 1 mm) were prepared with five composites in two different shades (n=10). After light-curing, the specimens were stored in dark containers with artificial saliva at 37 C for 24 hours. Baseline color was measured by CIEL*a*b* using a colorimeter (Easy-Shade, VITA). Half of the specimens were subjected to a discoloration process in a cigarette smoking machine (SM) and the other half to an immersion in whiskey (WH) for 24 hours. Another color measurement was performed for discolored specimens. The samples subjected to smoking were immersed in whiskey (SM/WH) and those subjected to whiskey immersion were subjected to cigarette smoking (WH/SM) followed by another color measurement. Color changes (Delta E*) were calculated and submitted to repeated measures 4-way ANOVA and Tukey tests (P < 0.05). Results: The most significant color change was observed after WH/SM (Delta E* = 22.8-31.5) discoloration process, followed by SM (Delta E* = 7.0-18.0), SM/WH (Delta E* = 4.9-16.5) and WH (Delta E* = 2.0 to 9.5). Translucent shades were more susceptible to discoloration than enamel shades. All the groups, with the exception of two, showed a significantly high perceptible color change (Delta E* > 3.3). Based on the results, the color stability of dental composites was affected by the discoloration process and was material and shade dependent.

Objective: The goal of the study was to analyze dental attendance and self-assessment of dental status among Israeli military personnel, according to gender, education, and smoking status. Methods: Data were analyzed from a computerized questionnaire on dental attendance and dental status, completed by military personnel who attended one medical clinic for the required periodic medical examination between 1998 and 2006. Results: For 60% of the respondents, the last dental visit was within the previous 12 months. The last dental visit was for scheduled treatment for 49.8%, a dental examination for 21.5%, and emergency dental treatment for 12.2%. College graduates rated their dental self-care higher than non-college graduates, and nonsmokers rated their self-care higher than smokers. Of the participants, 50.9% considered their own dental status good or excellent and 7.2% considered their oral health status poor. No significant differences were found according to gender. Conclusions: The findings indicated high dental attendance but low self-perception of dental status in Israeli military personnel in comparison with the Israeli general population and low attendance in comparison with U.S. Army personnel. A compulsory periodic dental examination among Israeli military personnel, similar to the required periodic medical examination, is recommended.
