Aim: The purpose of this study was to determine the prevalence and severity of temporomandibular joint disorders among postgraduate students at Egyptian universities.
Materials and methods: 840 postgraduate students from different Egyptian universities were recruited and answered Fonseca's questionnaire. Out of the 840 respondents, 593 were included and evaluated using Fonseca's anamnestic index to classify them according to the severity of the disorder.
Results: The prevalence of temporomandibular disorders among the included population was 73.4%. The most common degree of severity reported was the mild category being 57% followed by moderate (31.7%) then severe (11.3%). Temporomandibular disorders were prevalent among females with a frequency of 73.3% while 26.7% for males. There was significant association between the temporomandibular disorders and sex (P<.001).
Conclusion: There's high prevalence of temporomandibular disorders among Egyptian postgraduate students. There's an association between sex and prevalence of temporomandibular disorders, with females being more susceptible to the development of temporomandibular disorders.
