It is often accompanied by xerostomia and marked oral changes. The pathogenetic mechanisms linking oral pathology and autoimmune liver disease remain poorly investigated.</p> <p><bold>AIM:</bold> This work aimed to correlate the pattern of oral changes in patients with PBC with disease duration, stage, and clinical-course characteristics.</p> <p><bold>METHODS:</bold> Forty-eight women aged 43 to 69 years with confirmed PBC were examined. Disease stage (early or advanced) was determined using laboratory data and transient elastography. Oral assessment included clinical dental examination, radiography, evaluation of salivary gland function (sialometry, salivary pH measurement, ultrasonography), and detection of key periodontopathogens via polymerase chain reaction. Statistical analysis was conducted using R software with regression modeling.</p> <p><bold>RESULTS:</bold> Advanced-stage PBC was identified in 52% of cases; xerostomia was present in 68.75%. Liver stiffness was positively correlated with xerostomia severity (τ = 0.54, p &lt; 0.001), periodontitis stage (τ = 0.56, p &lt; 0.001), and oral-hygiene status as well as the number of identified periodontopathogens. More severe oral abnormalities were observed with longer disease duration. Gamma-glutamyltransferase and alanine aminotransferase levels showed positive correlations with xerostomia and periodontitis severity.</p> <p><bold>CONCLUSION:</bold> Oral abnormalities in patients with PBC are closely associated with disease severity, duration, and liver function biomarkers. These changes may serve as supplementary clinical indicators of disease progression and support the need for a multidisciplinary approach to management.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Первичный билиарный холангит — хроническое иммуно-опосредованное заболевание печени, наблюдающееся преимущественно у женщин (распространенность 2–40 случаев на 100 тыс. населения), которое сопровождается развитием ксеростомии и выраженных изменений полости рта. Патогенетические аспекты взаимосвязи стоматологической патологии и аутоиммунного заболевания печени мало изучены.</p> <p><bold>Цель</bold> — сопоставить характер изменений в полости рта при первичном билиарном холангите с длительностью, стадией и особенностями течения заболевания печени.</p> <p><bold>Методы.</bold> Обследовано 48 женщин с подтвержденным диагнозом первичного билиарного холангита в возрасте от 43 до 69 лет. Стадию заболевания (ранняя, поздняя) устанавливали на основании лабораторных данных и результатов транзиторной эластометрии печени. Анализ состояния полости рта включал клинический стоматологический осмотр, рентгенологическое исследование, оценку функции слюнных желез (сиалометрия, измерение рН слюнных желез, ультразвуковое исследование слюнных желез), диагностику основных пародонтопатогенов методом полимеразной цепной реакции. Статистический анализ проводился в программной среде «R» с применением моделей регрессии.</p> <p><bold>Результаты.</bold> В 52% наблюдений установлена поздняя стадия первичного билиарного холангита, у 68,75% больных отмечена ксеростомия. Установлена прямая корреляция между жесткостью печени и степенью ксеростомии (τ=0,54, p &lt;0,001), стадией пародонтита (τ=0,56, p &lt;0,001), а также гигиеническим состоянием рта и количеством выявленных пародонтопатогенов. Более тяжелые стоматологические нарушения регистрировались при большей давности заболевания. Уровни гамма-глутамилтрансферазы и аланинаминотрансферазы положительно коррелировали с показателями ксеростомии и тяжестью пародонтита.</p> <p><bold>Заключение.</bold> Нарушения в полости рта при первичноv билиарноv холангитt тесно связаны с тяжестью и длительностью основного заболевания, а также с лабораторными показателями функции печени. Эти изменения могут использоваться как дополнительные клинические маркеры, отражающие прогрессирование первичного билиарного холангита и необходимость комплексного междисциплинарного подхода к лечению.</p></trans-abstract><kwd-group xml:lang="en"><kwd>primary biliary cholangitis</kwd><kwd>xerostomia</kwd><kwd>oral-hygiene status</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>первичный билиарный холангит</kwd><kwd>ксеростомия</kwd><kwd>гигиеническое состояние ротовой полости</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Xu H, Yanny B.
