Комплексная терапия включала профессиональную гигиену, санацию полости рта, общую медикаментозную терапию и местное применение геля с фульвовой кислотой в течение 21 дня. Оценка проводилась клинически, с помощью пародонтального зонда и аутофлюоресцентной стоматоскопии (АФС), и путем исследования маркеров оксидативного стресса (малоновый диальдегид, каталаза) в ротовой жидкости. Результаты показали полную эпителизацию эрозий у 92% пациентов к 28 дню, значительное уменьшение площади воспаления по данным АФС и достоверную нормализацию биохимических показателей, что свидетельствует о снижении оксидативного стресса и высокой терапевтической эффективности изучаемого геля.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to evaluate the efficacy of a fulvic acid-based gel in the complex treatment of the erosive-atrophic form of oral lichen planus (OLP) in 20 patients (12 women and 8 men, mean age 45–57 years). The comprehensive therapy included professional hygiene, oral sanitation, general medication therapy, and topical application of the fulvic acid gel for 21 days. Assessment was performed clinically, using a periodontal probe and autofluorescence stomatoscopy (AFS), and by investigating oxidative stress markers (malondialdehyde, catalase) in the oral fluid. The results showed complete epithelialization of erosions in 92% of patients by day 28, a significant reduction in the inflammation area according to AFS data, and a significant normalization of biochemical parameters, indicating a reduction in oxidative stress and the high therapeutic efficacy of the studied gel.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>красный плоский лишай</kwd><kwd>слизистая оболочка рта</kwd><kwd>фульвовая кислота</kwd><kwd>оксидативный стресс</kwd><kwd>малоновый диальдегид</kwd><kwd>каталаза</kwd><kwd>антиоксидантно-прооксидантный индекс</kwd><kwd>аутофлюоресцентная стоматоскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oral lichen planus</kwd><kwd>oral mucosa</kwd><kwd>fulvic acid</kwd><kwd>oxidative stress</kwd><kwd>malondialdehyde</kwd><kwd>catalase</kwd><kwd>antioxidant-prooxidant index</kwd><kwd>autofluorescence stomatoscopy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Рабинович О.Ф., Рабинович И.М., Бабиченко И.И.
