About 71.42% of the participants were female and 28.58% were male. Irritation fibroma had the highest frequency (20%). The most frequent lesion among women was lichen planus with a prevalence of 20% and the most frequent lesion among men was irritation fibroma with a prevalence of 30%. The highest frequency was observed in the age group of 21-30 years. Squamous papilloma, lichen planus, and irritation fibroma were the most common lesions with a prevalence of 25%.
