An observational study in Temporomandibular Disorder (TMD) and Bruxism, sponsored by Istanbul Physical Medicine Rehabilitation Training and Research Hospital. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 50 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-06-23.
Sponsored by Istanbul Physical Medicine Rehabilitation Training and Research Hospital · Observational
This study aims to determine the frequency of temporomandibular disorders (TMD) and bruxism in elite basketball referees and to compare the findings with healthy controls. Basketball referees are exposed to high stress levels and maintain a prolonged parafunctional activity by holding a whistle between their teeth during matches, which may increase the risk of TMD and bruxism.
Participants will be evaluated using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), including Axis I and Axis II assessments. Additionally, ultrasonographic measurements of the masseter and temporalis muscle thickness will be performed both at rest and during clenching. The relationship between TMD, bruxism and ultrasonographic findings will be analyzed.
609 studies on the registry are indexed under Temporomandibular Joint Disorders; 160 are open to participants now.
This study's enrollment of 76 is below the median of 90 across 165 observational studies indexed under Temporomandibular Joint Disorders.
