Prevalence and correlations of temporomandibular disorders in Northern Jordan using diagnostic criteria axis I

Abstract

AIM: The aim of the present study was to document the prevalence and possible correlations of temporomandibular disorders (TMD) in a sample of participants from Northern Jordan. METHODS: A total of 368 adult participants were consecutively selected from visitors to a major health facility in Northern Jordan and examined according to the diagnostic criteria (DC) for TMD (DC/TMD) protocol. Patients with conditions that could interfere with TMD diagnosis were excluded. Pearson correlation and analysis of variance statistical tests were applied. Statistical significance was set at P ≤ 0.05, with a 95% confidence interval. RESULTS: A total of 98 patients (26.7%) had 1 TMD diagnoses; 60 participants (16.3%) had a pain-related TMD diagnosis, 48 (13%) had intra-articular joint disorders (IAD), and 16 had both pain-related TMD and IAD. In addition, six (1.6%) participants were found to have degenerative joint disease. Females were found to have a higher prevalence of pain-related TMD diagnoses (r = 0.111, P = 0.034) and headache (r = 0.129, P = 0.013) than males. Clicking was positively related to both pain-related TMD (r = 0.154, P = 0.003) and IAD (r = 0.576, P = 0.000). CONCLUSION: The frequency of TMD and related features was reported in a Northern Jordanian population using DC/TMD for the first time, and the results are comparable to other populations in similar study settings.
