Abstract

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.

Highlights

METHODSTemporomandibular disorder (TMD) is currently understood as a musculoskeletal pain syndrome, with overlapping comorbidities of physical signs and symptoms, as well as changes in behavior, emotional status, and social interactions [1,2]
Subgroups of students were analyzed who obtained mean scores above the percentiles established for each dimension alone, and each subgroup was composed of 19 students according to P66 for emotional exhaustion (EE) and DP and P33 for personal accomplishment (PA)
The results of the present study revealed that 8.7% of dentistry students showed an indication of burnout syndrome (BS) presence, with higher three-dimensional percentiles when compared to the cutoff values established for the sample

Summary

Introduction

METHODSTemporomandibular disorder (TMD) is currently understood as a musculoskeletal pain syndrome, with overlapping comorbidities of physical signs and symptoms, as well as changes in behavior, emotional status, and social interactions [1,2]. The main predictors for the development of painful TMD are the presence of other painful conditions, non-painful orofacial symptoms (e.g., selfreport of parafunctions), frequency of somatic symptoms, poor sleep quality, and genetic and epigenetic factors [2] Among comorbidities, those related to emotional states, such as anxiety and depression, have higher relevance in the perception of painful TMD [1,2,3]. Recent studies have shown that psychological factors such as catastrophizing, lack of assertiveness in requesting help, and delay in seeking treatment related to the fear of the unknown may be associated with the maintenance of TMD pain [6,7] In this sense, burnout syndrome (BS) is characterized by a psychological reaction due to emotional tension, which leads to a reduction of motivation, interest, and abilities regarding professional activities/studies, causing serious negative consequences in the individual’s social, professional, and family life [8,9]. Some studies have shown that in dentistry students, this prevalence varies between 7 and 20% [11,12,13,14]
