The pathology of the hepatobiliary system significantly affects the state of the organs of the oral cavity. A clinical and index study of the state of periodontal tissues in 122 patients was conducted, which showed the prevalence of periodontal disease in patients with chronic acalculous cholecystitis. The examined patients were divided into groups depending on the treatment method, and the result was evaluated before treatment, directly after treatment and 6 months following treatment. Antidysbiotic hepatoprotector and 2% thiotriazolin ointment were included in the combination therapy. Studies have shown that patients with hepatobiliary pathology have increased likelihood of periodontal diseases, and after treatment, periodontal indicators and the hygiene index are significantly reduced, especially in the group where the proposed scheme was used, and the long-term results were stable for 6 months.
