MONTEIRO DE BARROS, Letizia et al. Occurrence of periodontal disease, caries, and tooth loss in smoker patients of a Dental Clinic-School in the south region of the state of Minas Gerais: case control study. RFO UPF [online]. 2016, vol.21, n.3, pp. 414-419. ISSN 1413-4012.

Objective: to compare the occurrence of periodontal disease, caries, and tooth loss in adult smokers of both genders admitted for integrated dental treatment in a dental school, to a non-smoker control group. Methods: dental and periodontal clinical exams were evaluated in medical records of 31 smokers and 46 non-smokers regarding the occurrence of bleeding and/or gingival suppuration, loss of periodontal support by pocket or gingival retraction, tooth hypermobility, and decayed, missing, and filled teeth. Student t test (p≤0.005) was used to compare the averages between groups, and the correlation between variables was obtained by multivariate analysis. Results: smoker patients reported smoking an average of 11.32 ± 8.599 cigarettes/day and 54.83% of them smoked more than 10 cigarettes/day. It was observed that variables of number of teeth with insertion loss, periodontal pocket, gingival retraction, hypermobility, bleeding/suppuration, average insertion loss (in mm), and age are highly correlated and directly proportional. The number of healthy teeth was inversely proportional to age, and plaque index was correlated to the number of decayed and lost teeth and dental calculus. However, no statistically significant difference was observed between groups for any parameter, except for tooth loss, with smokers having an average of more lost teeth than non-smokers (p=0.0171). Conclusion: smoking did not significantly influence the occurrence of caries or periodontal disease in the population studied, but smokers present higher tooth loss than non-smokers, and they should be advised to quit smoking.
