Association of Carcinogenic Oral Habits with Oral Squamous Cell Carcinoma

OBJECTIVE: To determine the association among betel nut, betel quid or smoking alone, and betel quid combined with smoking in subjects reporting with oral sub mucous fibrosis, oral submucous fibrosis with malignant transformation in to cancer and oral squamous cell carcinoma. METHODOLOGY: An analytical cross sectional, multi centric study of n = 1009 cases collected through non-probability convenience sampling. These n=1009 subjects were subdivided into four groups: group 1, who consumed areca nut only; group 2, who chewed betel quid along with areca nut; group 3, who used betel quid and smoked; and group 4, who had no chewing habits history but were smokers. These changes were further confirmed with the help of biopsy reports of the subjects with OSMFCa and OSCC. Chi square test was performed to find out association of chewing habits with the progression of disease state. Level of significance was kept at p
