Relationship between temporomandibular disorder symptoms signs and Burnout syndrome among dentistry students

摘要

BACKGROUND AND OBJECTIVES: Temporomandibular disorder and Burnout syndrome are influenced by emotional factors. This study aimed at prospectively evaluating Burnout syndrome dimensions and their relationship with temporomandibular disorder signs and symptoms in a sample of dentistry graduating students. METHODS: Sample was made up of dentistry graduating students (23?±2.5 years), who have answered the Maslach Burnout Inventory questionnaire, students survey, and the ProDTM-Multi. Questionnaires were answered once a year, considering first, second and third year of the course (2013/2014/2015). Statistical analysis has compared Burnout syndrome dimensions between genders and has tested their correlation with total ProDTMMulti score, as well as variations between scores of this syndrome dimensions along the years by gender. RESULTS: Considering total sample, there has been increase in risk zone frequency for Burnout syndrome as years went by. There has been significant difference between males and females for emotional exhaustion in the three evaluated years (p=0.002, p=0.003, p=0.01, respectively) and also for disbelief in the last year (p=0.02), being higher for females. There has been significant correlation of ProTD-MMulti scores and emotional exhaustion among females in the first and second evaluated years (p=0.0004, p=0.04). CONCLUSION: It seems to be correlation between emotional exhaustion and perception of temporomandibular signs and symptoms among females, and a trend to Burnout syndrome dimensions scores increase as course progressed.
