RESUMEN
Background and Objectives: Quid-chewing habit is a common and old tradition in India. It causes various potentially malignant disorders. Therefore, a study was undertaken to analyze the association of various quid-chewing habit patterns and different oromucosal lesions. Materials and Methods: A cross-sectional study was conducted on 150 cases, where all the individuals selected were having quid-chewing habit and oromucosal lesions. Detailed habit history was taken through preformed questionnaire, clinical examination was done, and the lesion was subjected to incisional biopsy and confirmed histopathologically. Results: The male to female ratio of various quid-chewing habit and oromucosal lesions was 9:1. The middle aged were more commonly involved. Of the various types of quids chewed, a combination of processed betel and processed tobacco which is commercially available was used by majority of the individuals. Oral submucous fibrosis (OSMF) was seen in majority of the cases. Interpretation and Conclusion: The present study confirms the association between betel, tobacco, and various lesions such as OSMF, leukoplakia, chewer's mucosa, lichenoid reaction, and chemical burn. It also confirms the strong association of betel to OSMF and tobacco to leukoplakia
