Oral cancer is one of the most common life threatening diseases in India. Tobacco and alcohol are considered to be the most risk factors for oral cancer. This study was conducted to investigate the association of tobacco and poly-ingredient oral dip products with oral cancer. A case-control study of 350 cases and 350 controls, over a period of 19 months, between February 2005 and September 2006 was carried out in Pune, India. The self-reported information about the consumption of tobacco, poly-ingredient oral dip products, alcohol, dietary habits and demographic status were collected by a researcher made questionnaire. Univariate and multivariate analysis were used to identify the risk of substances abuse. The frequency of smoking, smokeless and oral dip products in cases were significantly higher than controls (P < 0.0001). Among smoking types, bidi (P < 0.0001, OR = 4.1 95% CI = 2.4 - 6.9), of smokeless types, chewing tobacco (P < 0.0001, OR = 8.3, 95% CI = 5.4 - 13.0) and mishiri (P < 0.0001, OR = 3.3, 95% CI =2.1 - 5.4), and of oral dip products, consumption of gutkha (P < 0.0001, OR = 12.8, 95% CI =7.0 - 23.7) and supari (P < 0.0001, OR = 6.6, 95% CI =3.0 - 14.8) indicated strong association with oral cancer upon adjustment. This study provides strong evidence that gutkha, supari -areca nut- chewing tobacco (tobacco flakes), bidi smoking and mishiri (tobacco powder, which applied as a tooth and gum cleaner) are independent risk for oral cancer.
