Objective:

To synthesize evidence on prognostic factors associated with pain and functional outcomes in patients with temporomandibular disorders (TMD).

Approach:

Key Findings:

Pain triggered by movement or palpation is associated with poorer outcomes.
Joint pain with sound and muscle pain during movement are strong predictors of worse prognosis.
Shorter pain duration and greater pain-free mouth opening are protective factors.
Higher baseline pain intensity predicts poorer functional outcomes.
Demographic and psychosocial factors showed no consistent association with pain or function.

Interpretation:

Observable pain responses during examination may be more informative for prognosis than demographic or psychosocial characteristics.

Limitations:

Evidence is low to very low certainty due to methodological heterogeneity.
Lack of studies examining the natural course of TMD without focusing on predictive variables.

Conclusion:

Findings should inform risk stratification but not guide treatment decisions without further longitudinal studies. Clinicians should use results as part of a broader assessment.
