Introduction: Tobacco use and its association with oral diseases are a major contributor to the global oral disease burden and are responsible for various oral mucosal changes among adults. Objective: The objective of this study was to assess oral mucosal changes among male tobacco users and nonusers, aged 15 years and older. Materials and Methods: A comparative cross-sectional study was conducted among 300 tobacco users and 300 nonusers, who were matched for age. Male patients aged ≥15 years attending outpatient department were included. Data were collected using pretested structured questionnaire (Cronbach α = 0.88) and modified World Health Organization oral health assessment form 2013. Statistical analysis was carried out using the Statistical Package for the Social Sciences (SPSS) software, version 20.0; descriptive statistics, chi-square test, Pearson correlation, and linear regression were used; and P ≤ 0.05 was considered as statistically significant. Results: The prevalence of oral mucosal lesions in this study was 27.7%, whereas in tobacco users, it was 44.7%, and in tobacco nonusers, it was 10.7%. Smokeless tobacco users were associated with oral mucosal lesions such as oral cancer (33.3%) and leukoplakia (33.3%), whereas individuals who consume smoke form of tobacco were associated with smoker’s palate (29.1%) (P = 0.001). The chance of occurrence of oral mucosal changes was 0.373 units more among tobacco users than that among tobacco nonusers, which was statistically significant (P = 0.001). Conclusion: Oral mucosal changes were found to be high among tobacco users compared to those among tobacco nonusers. Smoking tobacco was associated with benign lesions such as leukoplakia and nicotine stomatitis, whereas smokeless tobacco was associated with potentially malignant lesions such as oral cancer, which reflect the lack of awareness or ignorance for the oral health issues.
