Temporomandibular disorders and Burnout syndrome in students of the eighth period of dentistry course

ABSTRACT Objective: To investigate the incidence of painful temporomandibular disorders (TMD) and Burnout Syndrome (BS) in Dentistry students, based on the subjective perception of signs and symptoms, and to verify if there is a coexistence relation between these conditions. Methods: 57 students (8th period of the dentistry course, 23 years mean age), 39 women and 18 men, responded to the Maslach Burnout Inventory Questionnaire – Students Survey (MBI-SS), ProTMDMulti and were evaluated for the presence of TMD diagnosis (DC/TMD). Results: The incidence of TMD was 22% and BS was 8.7%. Among the students with BS, 80% had a TMD diagnosis, as well as a greater subjective perception of TMD signs and symptoms and a longer duration of pain. They also showed higher scores of signs/symptoms perception for situations involving orofacial function. Conclusion: There seems to be a clinical coexistence between the BS and painful TMD in the studied sample, Dentistry students with BS and high scores on the MBI-SS are more likely to have painful TMD.

摘要
研究目的：基于牙科学生对体征与症状的主观感知，调查疼痛性颞下颌关节紊乱病（Temporomandibular Disorders, TMD）与职业倦怠综合征（Burnout Syndrome, BS）的患病率，并验证二者是否存在共存关联。
研究方法：纳入57名牙科专业8年级学生（平均年龄23岁，其中女性39名、男性18名），要求其填写马氏职业倦怠量表学生版（Maslach Burnout Inventory – Students Survey, MBI-SS）与ProTMDMulti问卷，并依据DC/TMD标准评估其是否罹患TMD。
研究结果：TMD患病率为22%，BS患病率为8.7%。在合并BS的学生中，80%同时符合TMD诊断标准；该群体对TMD体征与症状的主观感知程度更高，疼痛持续时间更长，且在涉及口面部功能的场景中，其体征/症状感知评分也更高。
研究结论：本次研究样本显示，职业倦怠综合征与疼痛性颞下颌关节紊乱病似乎存在临床共存关系；罹患BS且马氏职业倦怠量表学生版评分较高的牙科学生，罹患疼痛性TMD的风险更高。
