A Study to Analyze Different Patterns of Quid Usage among Subjects with Oral Submucous Fibrosis in Mangalore Population.

. Oral submucous fibrosis (OSF) is a potentially malignant disorder associated with the usage of areca nut. Usage of processed forms of areca nut is popular among the youth and its carcinogenic effects are not well known. Due to large immigrant population, various patterns of areca nut usage are seen. The aim of this study is to assess the various quid chewing patterns and their association with severity of OSF. . A cross-sectional study was carried out with 250 cases clinically and histologically diagnosed as having OSF lesion that were selected and subjected to a detailed habit history which was recorded through preformed questionnaire. The data obtained was statistically analyzed. . Among the 250 subjects, males were seen to be affected more than females within the age group of 26-35 years and were having clinical stage I OSF. A combination of processed areca nut and processed tobacco was used by the majority of the subjects with duration of 1 to 5 years, at a frequency of 3 to 5 quids per day. . The present study confirms the association between oral submucous fibrosis and the quid containing processed areca nut and processed tobacco and also highlights the increasing youth population using the processed forms of areca nut.
