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.

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(1,12) = 6.84; P < .05) and prolonged abstinence (F(1,12) = 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.

AIM: Dental professionals have the potential to influence global smoking rates. This study evaluated the impact of a tobacco curriculum on smoking behaviour and attitudes toward smoking in dental students. METHODS: Immediately before and three years after the implementation of a tobacco curriculum with a no-smoking policy, a questionnaire was administered to students to obtain information about their smoking behaviour and attitudes toward smoking. RESULTS: The number of students who responded to the questionnaire was 580 in 2003 and 554 in 2006. The smoking rate decreased significantly from 35% in 2003 to 26% in 2006; however, analysis of data for each school year suggested that this was due to the prevention of smoking initiation rather than quitting smoking. Attitudes toward patient smoking and public policy were more positive in non-smokers than in current smokers. Improvement in attitudes toward patient smoking was smaller in current smokers than in non-smokers. Little improvement occurred in attitudes toward public policy in both non- and current smokers. CONCLUSIONS: Implementation of a tobacco curriculum was effective in preventing smoking initiation and improving attitudes toward patient smoking in students. Further measures are necessary to improve attitudes toward public policy and to discourage smoking among students.

Abstract: Smoking exerts detrimental effects on dental treatment and oral health. Our goal was to evaluate effectiveness in terms of the abstinence rate in smoking-cessation intervention delivered by dental professionals. Individuals who were willing to quit smoking were randomly assigned to either an intervention or a non-intervention group. Intensive intervention was provided, consisting of 5 counseling sessions, including an additional nicotine replacement regimen. Reported abstinence was verified by the salivary cotinine level. Thirty-three persons in the intervention and 23 in the non-intervention group started the trial. On an intent-to-treat basis, 3-, 6- and 12-month continuous abstinence rates in the intervention group were 51.5%, 39.4%, and 36.4%, respectively, while the rates in the non-intervention group were consistent at 13.0%. Adjusted odds ratios (95% confidence interval) by logistic stepwise regression analyses were 7.1 (1.8, 28.5), 8.9 (1.7, 47.2), and 6.4 (1.3, 30.7), respectively. Intensive smoking-cessation intervention in the dental setting was therefore effective.

The U.S. Food and Drug Administration announced today a ban on cigarettes with flavors characterizing fruit, candy, or clove. The ban, authorized by the new Family Smoking Prevention and Tobacco Control Act, is part of a national effort by the FDA to reduce smoking in America. Smoking is the leading preventable cause of death in America.
