Abstract

AimThe aim of the present study was to determine the prevalence of temporomandibular disorder (TMD) symptoms among dentistry students at James Cook University in Australia, and to determine the associations of TMD symptoms with demographic parameters and compare the prevalence to that of the Australian general population.

MethodsThe study was conducted at the School of Dentistry, James Cook University. Axis I symptom questionnaire of diagnostic criteria for TMD was used to assess the prevalence of TMD symptoms. Additional questions were included to gather demographic information on the participants. Data were collected anonymously via the online survey tool, SurveyMonkey.

ResultsThe overall prevalence of TMD symptoms in this cohort was 77.2%. The most common TMD symptoms were pain (48.5%) and joint noises (48.5%). Females reported a significantly higher prevalence of TMD symptoms than males, with 73 of 88 female respondents (83%) and 32 of 48 male respondents (66.7%) reporting at least one symptom of TMD (P=.030).

ConclusionsThe overall prevalence of TMD symptoms in the population studied was 77.2%, with female preponderance of TMD symptoms (83%). This is higher than the estimated prevalence (23%) in the Australian general population.
