The role of pain-related disability on treatment outcome and psychosocial symptoms in patients with temporomandibular disorders - a pilot study.

Patients with TMD subtype 3 (moderate/severe disability) had the highest NRS scores and described their symptoms as most severe at each time point, statistically significantly so at 1-month and 6-month follow-up ( < .05). The highest proportion of depressive symptoms was found in TMD subtype 3 ( < .05). The current pilot study showed that moderate/severe TMD-related disability, based on the GCPS 1.0 as a screening tool, may be linked with poor treatment outcome and depressive symptoms. Studies with larger samples are needed to confirm the results.
