[A study on the relationship between etiology and influencing factors of burning mouth syndrome]

To analyze the etiology and related influencing factors of burning mouth syndrome (BMS).

A total of 109 patients with BMS who visited the Department of Stomatology of Shengjing Hospital of China Medical University from November 2022 to October 2023 were selected, and 84 healthy volunteers who participated in the survey during the same period were selected as the control group. The basic information of the research subjects was recorded, and oral health status, periodontal health status and psychological status of the research subjects were evaluated. Student's t test, Chi-square test and binary logistic regression analysis were used to analyze the factors affecting the incidence of BMS with SPSS 27.0 software package.

Mono-factor analysis showed that residual crown, residual root, periodontitis, anxiety status, depressive status, sleep disorders, menopause, diabetes, digestive system diseases and lacunar infarction were related to the incidence of BMS (P＜0.05). The variables with P＜0.1 in mono-factor analysis were selected for multivariate logistic regression analysis. The results showed that periodontitis, COVID-19, anxiety status, depressive status, sleep disorders, lacunar infarction, and digestive system diseases were factors affecting the incidence of BMS (P＜0.05 and OR＞1).

The diagnosis and treatment of BMS require multidisciplinary cooperation of specialists such as psychiatry, neurology and gastroenterology, and active treatment of systemic or related diseases. In addition to strengthening oral hygiene and periodontal health management for patients, clinical practitioners should also pay attention to the aggravation of BMS patients' pain intensity, sleep quality and anxiety caused by COVID-19 pandemic, and provide timely psychological counseling to better control the development of BMS.
