OBJECTIVE The present cross-sectional study following the STROBE guidelines was conducted to assess the prevalence of oral mucosal lesions among males, females, and eunuchs residing in Bhopal city, Madhya Pradesh India. METHODS Based on convenient non-probability snowball sampling technique, all the self-identified eunuchs residing in the city of Bhopal who were present at the time of examination and who fulfilled the selection criteria were examined. A cross section of the general population (males and females) residing in the same locality where these eunuchs live was also examined. The World Health Organization (WHO) oral health assessment proforma (1997) was used to collect the information on oral mucosal lesions. All the obtained data were analyzed by using a Statistical Package for Social Sciences version 20. RESULTS Overall prevalence of oral mucosal lesions was 127 (19.9%) among the study subjects. Fifty-nine (28.5%) eunuchs, 56 (25.7%) males, and 12 (5.6%) females were observed to have some oral mucosal lesions. Oral submucous fibrosis (6.4%), leukoplakia (5.5%), and traumatic ulceration (4.2%) were the major oral mucosal conditions observed. CONCLUSIONS The information presented in this study adds to our understanding of the common oral mucosal lesions occurring in the eunuch population. Efforts to increase patient awareness of the oral effects of tobacco use and to eliminate the habit are needed to improve the oral and general health of eunuchs.
