Prevalence of tobacco smoking and most frequent oral lesions, precancerous lesions (oral lichen planus and leukoplakia) and oral cancer. Exsmokers who have stopped smoking more than 10 years ago are considered as non-smokers. Statistically significant association was found only between oral cancer and tobacco smoking (p < 0.05, chi-square = 40.23)
