Analysis of Oral Leukoplakia and Tobacco-Related Habits in Population of Chengalpattu District- An Institution-Based Retrospective Study.

Objective The study aimed to evaluate the prevalence of oral leukoplakia and to assess the risk of developing oral leukoplakia in patients with tobacco-related habits among the populations of Chengalpattu district, Tamil Nadu, India.  Materials and Methods Incidence and prevalence of oral leukoplakia differ among different populations in India due to cultural and demographic diversities. The results obtained from this study can be used as a reference in future research and policy-making for tobacco control. Data for this study were manually ascertained from the Department of Oral Pathology and Microbiology, SRM Kattankulathur Dental College and Hospital, SRM Institute of Science and Technology, Potheri, Chengalpet district, Tamil Nadu, India. The medical records of the patients diagnosed with the abnormalities and diseases of the oral mucosa, especially the white lesions of the oral cavity, between January 2011- March 2021 (10 years). The basic inclusion criteria for this study were to include the histopathology reports of the white lesions with no malignant changes during clinical diagnosis. The data was analyzed based on age, gender, tobacco-related habits, and histopathological diagnosis. The exclusion criteria for the study were the cases reported as carcinoma, patients associated with syndromes, biopsies outside the mentioned period, and those patients with incomplete clinical or histopathological details. Results Among 141 white lesions, about 85 cases [60.2%] were confirmed as oral leukoplakia, of which the study population had 55 (64.7%) males and 30 (35.3%) females. The age group which was commonly seen was 41-60 years. About 80% of the population with oral leukoplakia had the habit of tobacco consumption. The use of tobacco products was seen more commonly in the male population than the female, and consumption of tobacco and alcohol was seen in 6% of the population. In our study, we found the study population had the habit of using smokeless tobacco rather than smoking cigarettes and bidis. About 20% of the population diagnosed with leukoplakia did not have any habits. The most commonly affected site was buccal mucosa (67%), followed by the tongue (12%). Conclusion Our study shows a statistical association between oral leukoplakia and tobacco product consumption among the population of Chengalpattu district. The oral health care providers must take utmost care and vigilance to diagnose the lesion at its earliest stage and give appropriate treatment modalities and effective tobacco interventions.
