SOME FEATURES OF CLINICAL MANIFESTATION OF TYPICAL AND COMPLICATED FORMS OF LICHEN PLANUS ON THE ORAL MUCOSA ACCORDING TO OBSERVATION DATA

Abstract

Relevance. Lichen planus is a chronic disease affecting the skin and oral mucosa. There is no exact data on the prevalence of lichen planus, which is due to the late appeal of patients not only to dentists, but also to dermatologists. The aim of this study was to learn some of the features of the clinical manifestations of typical, exudative-hyperemic, erosive-ulcerative and bullous forms of lichen planus on the oral mucosa. Material and methods. In the present study, on the basis of screening examination of patients who applied for dental care in dental clinics and living in the cities of Ufa, Omsk, Nizhny Novgorod, Nahariya, Kazan, we studied some of the clinical features of various forms of lichen planus of the oral mucosa, and the peculiarities of their course. In the course of a comprehensive dental examination, all examined persons were divided into four study groups: 1 clinical group (39.5%) — patients with a typical form, 2 clinical group (25.6%) — patients with exudative-hyperemic form, 3 clinical group (6.9%) — patients with a bullous form, 4 clinical group (27.9%) — with an erosive and ulcerative form of lichen planus. Results. In the course of a comprehensive dental examination, in 39.5% of cases, a typical form of lichen planus was revealed, in 61.3% of cases it was bullous, exudative-hyperemic and erosive-ulcerative forms, with their prevalence in 70.9% of cases in females. The average age of patients diagnosed with a typical form of lichen planus was on average 42.5±3.5 years, exudative-hyperemic form — 48.2±3.8 years, bullous — 49.8±3.6, erosive ulcerative form — 50.6±3.2 years. The duration of development of all studied forms of lichen planus was on average from 4 months to 5 years (the development of the typical form was 1.4±0.4 years, exudative-hyperemic — 2.1±0.8 years, bullous form — 3.9±1.2, and the erosive and ulcerative form — 4.3±1.2 years.
