Abstract

The most commonly occurring type of keratosis would be tobacco pouch keratosis or smokeless tobacco
associated keratosis, frictional keratosis, a chronic frictional keratosis on the buccal mucosa can lead to
something called morscicatio buccarum. Although clinical features are very important and should be one
of the important factors in diagnosis, epidemiology should also be considered while arriving at a concrete
diagnosis. The aim of the present study was to retrospectively analyze the prevalence of different clinical
variants of Keratosis in patients visiting Saveetha Dental College. Retrospective data of 195 patients was
obtained and segregated. Inclusion criteria included that they should have visited the University between
June 2019 and April 2020. Once the data was obtained and verified, it was statistically analyzed using SPSS
by IBM version 20. Most common clinical variant was Tobacco pouch Keratosis (64.6%) followed by
Frictional Keratosis (28.7%). Mean age of the patients was 37.40 + or -10.98 years. Tobacco pouch keratosis
occurring most commonly in lower arch (67.46%) whereas the Frictional keratosis most commonly in
relation to both arches (42.85%). All common in 21-30 years age group. Statistically significant correlation
between the site of lesion and variant (p = 0.000) and between gender and variant (p=0.00 ) Increased Habit
Prevalence as the number of Tobacco pouch Keratosis cases are greater. Further multicentered studies and
awareness programs to help the society and prevent these lesions.
