Residents under orthodontic treatment or having been subjected to previous orthodontic treatment were excluded. Helkimo index was applied for temporomandibular joint diagnostic
... t diagnostic purposes A physical exploration of the temporomandibular joint and masticatory muscles was later conducted. Results: For result evaluation, descriptive statistics and chi-square ( 2 ) test were used. Statistical package SPSS 12 was used. Prevalence of temporomandibular disorder in residents was 66% of studied population. Signi cant result was obtained with respect to gender; it being higher in females with p .013. Greater incidence was observed in the rst residency years, as well as in non surgical specialties when compared to surgical ones. Conclusions: Prevalence of residents' temporomandibular disorder was similar to that reported worldwide in general population. The present study equally found greater prevalence in females. It would be signi cant to conduct another study to measure stress in resident physicians and relationship of stress with temporomandibular disorders.
