Background: Lichen planus (LP) is a pruritic, inflammatory skin, mucous membrane,
and hair follicle condition. It affects people of various ethnicities all over the world. 1.5
percent of men and 2.3 percent of women have oral LP. In some situations, it may be
inherited. The goal of this study was to determine the prevalence of oral, skin, and both
oral and skin lesions of LP in patients who visited a dental college's Department of Oral
Medicine and Radiology.
Material and methods: The prevalence of oral, skin, and oral and skin lesions in people
with LP was investigated in a cross-sectional study. We conducted a prospective study
for 18 months. All patients suspected of having LP were diagnosed based on clinical
presentation and histological investigation of mucosal and skin sample. SPSS (Statistical
Package for Social Sciences) software version 14 was used for statistical analysis. The
chi-square test was performed to determine statistical significance.
Result: There were 7,112 men and 8,544 females among the 15,656 patients who were
screened. LP appeared in 126 cases (0.80 percent). The prevalence of LP was found to
be higher in middle-aged adults (21-40 and 41-60 years old), with the lowest age being
14 and the highest being 67. There were no statistically significant differences between
genders in the skin LP group or the oral and skin LP groups, however there was a
substantial female preference in the oral LP group.
Conclusion: Oral LP was shown to be more common than skin LP, and both oral and
skin LP had a female predominance in this investigation.
