What predicts how bad TMD is, involving jaw, neck, and posture
Official title: An Investigation of Cranio-Cervico-Mandibular Factors Predicting the Severity of Temporomandibular Disorders
Run by Ankara Yildirim Beyazıt University · NCT07666360 · Data updated 2026-11-12
We will test if jaw dysfunction, neck position sense, and head/neck posture relate to how severe temporomandibular disorders are in adults.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 and older with a Fonseca Anamnestic Index score greater than 15.
✕Probably not a fit
Individuals without TMD-related symptoms or with recent TMJ/cervical treatment may have no personal benefit.

What this trial studies
This cross-sectional study will measure jaw function, cervical proprioception, craniovertebral angle, neck pain, and TMD severity using standardized tools. It will analyze how these factors are associated with each other to identify potential predictors of TMD severity. Data will come from a single point in time among adults without recent TMJ or cervical treatment. The goal is to understand relationships that could inform future prevention or management approaches.
Why it matters
Potential benefit: If successful, the findings could help clinicians identify patients at higher risk for more severe TMD based on jaw and neck-related measurements.
How similar studies have gone: Previous work has shown associations among jaw function, neck proprioception, and TMD severity, supporting the potential usefulness of these measures.
