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.

| Introduction|| |
Tobacco is the only legal drug that kills many of its users when used exactly as intended by manufacturers. World Health Organization (WHO) has estimated that tobacco use is currently responsible for the death of approximately six million people across the world each year. Majority of the tobacco-related deaths are expected to occur in developing countries such as India, where tobacco use is on the rise. According to the National Family Health Survey-4, conducted in 2015–2016, tobacco use was more prevalent among men, rural population, illiterates, poor, and vulnerable section of the society. The Global Adult Tobacco Survey (2016–2017) conducted among persons aged 15 years and older indicated that 28.6% were current tobacco users of which 10.7% were smokers and 21.4% were smokeless tobacco users. The Global Youth Tobacco Survey (2009) conducted among students aged 13–15 years stated that 14.6% were tobacco users. There is a weighty evidence that tobacco has a considerable influence on oral health directly or indirectly, leading to oral mucosal lesions. Its incidence and prevalence in south Asian countries is high owing to the increased production and consumption of tobacco. As there is no standard literature on oral mucosal changes among tobacco users in this region, collecting data from this population will help in building evidence that can be used to make the tobacco-cessation programs effective. Hence, this study was aimed to assess oral mucosal changes among tobacco users and nonusers, aged 15 years and older.
| Materials and Methods|| |
A comparative cross-sectional study was carried out in a dental institution of southern India. A total of 600 sample size was obtained, of which 300 tobacco users and 300 nonusers visited the outpatient department (OPD) of the southern university of India. Everyday purposively 10 tobacco users attending OPD were selected and for every tobacco user, one non-tobacco user matching with the age was included in the comparison group. This method was repeated for 3 months.
Questionnaire design and oral examination
An interview-based questionnaire was used, which consisted of details regarding age, socioeconomic status of the participant (Kuppuswamy scale 2015), and their oral hygiene practices, and questions regarding tobacco habit such as form of tobacco used, its frequency, and duration of the habit were collected using modified WHO questionnaire (2013). Data on oral mucosal changes were recorded using modified WHO oral health assessment form (2013) and following the criteria of “WHO Guide to epidemiology and diagnosis of oral mucosal diseases and conditions 1980,” by examining in adequate light using mouth mirror for cheek retraction (American Dental Association specified type III intraoral examination).
A detailed review of the multipronged aspect of the research and about the surrogate consent of the participants was elaborated for the acceptance and approval from the Institutional Ethics Committee (Pr. 36/IEC-SIBAR/CIR/15).
Before the study, an informed written consent was obtained from all the individuals willing to participate and ensured that participation was voluntary and anonymous. Surrogate consent was obtained from the participants below 18 years from their parents and guardians.
Data were entered into the Excel sheet, and were analyzed using IBM Statistical Package for the Social Sciences (SPSS) software for Windows, version 20.0 (IBM, Armonk, New York). The level of significance was set at <0.05. Descriptive and inferential analyses such as chi-square test, Pearson correlation coefficient, and linear regression were performed to ascertain the relation between different dependent and independent variables.
| Results|| |
Smokeless tobacco users were highly associated with oral mucosal conditions such as oral cancer (33.3%) and leukoplakia (33.3%), whereas in individuals who consume smoke in the form of tobacco were associated with smoker’s palate (29.1%), and this comparison was statistically significant (P = 0.001). The most common site for the occurrence of oral mucosal conditions in smokeless tobacco users was lip commissures (40%), and in smoke form of tobacco users, it was hard palate (29.1%), which was statistically significant (P = 0.01) [Table 1] and [Table 2]. The occurrence of any oral mucosal changes was more likely associated with tobacco users, and the chance of occurrence was 0.37 units lesser among tobacco nonusers. Likewise, the site of oral mucosal conditions was more likely associated with both smoke and smokeless form of tobacco users compared to that of non-tobacco users, and the change of occurrence was 0.670 times more in tobacco users than that in non-tobacco users [Table 3].

| Discussion|| |
In this study, 44.7% of tobacco users and 10.7% of nonusers reported oral mucosal changes such as malignant lesions, leukoplakia, smoker’s palate, and abscess. When compared to other south Indian dental hospitals, studies carried out by Saraswathi et al. (4.1%), Anzil et al. (14.9%), and Mathew et al. (28.2%) reported a low rate of Oral Mucosal Lesions in tobacco users where they are in accordance with the studies conducted by Sujatha et al. (36.1% in males), Patil et al. (54.1% in males), Aslesh et al. (44.6%), Mishra et al. (43.12%), and Kasat et al. (49.52%).
Oral mucosal lesions highly depend on the tobacco form used, its dose, frequency of intake, and duration of habit. In this study, oral mucosal lesions were found to be more associated with smokeless tobacco users (80%) when compared to smoke form of tobacco users (57.3%) and tobacco nonusers (10.7%), and these findings were in agreement with the studies carried out by Aslesh et al. (44.5%) and Vikneshan et al. (55.7%). The most prevalent oral mucosal lesions encountered in this study were smoker’s palate (22%) followed by leukoplakia (20%), whereas the common sites affected by the oral mucosal condition were palate (22%) followed by buccal mucosa (12.7%). These findings are similar to the findings in the studies conducted by Bhatnagar et al., Saunders, and Ramulu et al., which stated that smoking tobacco strikes the palate more directly resulting in smoker’s palate or nicotine stomatitis associated with definite atypical changes of the surface epithelium usually.
| Conclusion|| |
In this study, the number of tobacco users under younger age-group ranging from 15 to 24 years was more. So, an urgent need of intervention to curb the use of tobacco and its products lies in the fact that many teenagers are embracing the addiction. The lesions were found in those who indulged in various deleterious habits such as smoking and chewing tobacco. Smoking tobacco was associated with a wide range of benign oral mucosal lesions such as leukoplakia and nicotine stomatitis, whereas smokeless tobacco was associated with potentially malignant lesions such as oral cancer.
