Abstract
Background: Cigarette smoke contains dozens of chemicals and free radicals that could cause significant damage to the mucous membrane and dental tissues in the mouth. Therefore, the aim of this study was evaluation of oral health, mucosal lesions, dental and gingival status of smokers. Methods: In this cross-sectional study, 532 smokers including 369 males and 169 women were evaluated to determine the prevalence of mucosal lesions and dental health index. A dental student examined patients' punder dental illumination and mirrors. All of data collected via a questionnaire. Oral examination was classified into four groups as mucosal lesions, developmental oral anomalies, periodontal status, and DMFT index. Statistical analysis was performed using Stata software. Results: The average duration of smoking was 9.0 ± 4.8 years and the average number of cigarettes per day was 7.7 ± 6.49. Among the oral mucosal lesions, coated tongue (79.7%), pigmentation (43.4%), and halitosis (81.9%) and among the developmental disorders, lip pit (45.5%), Fordyce granules (36.6%) and fissured tongue (28.8%) were more prevalent. The prevalence of filling, missing, and decay teeth were 78.9%, 71.3%, and 92.9% respectively. The gingivitis and periodontal lesions were 89.8% and 10.6% respectively. A significant relationship observed between the oral-dental status and the smoking duration. Conclusion: The results of this study showed that oral and dental lesions have a high prevalence among smokers, and the incidence of these lesions is significantly associated with the duration of smoking habits and the number of cigarettes smoked per day.
