Abstract

Objectives: The aim of this randomized controlled study was to investigate the effect of depressive and non-specific physical symptoms on treatment outcome of temporomandibular disorders (TMD).

Material and methods: Eighty TMD patients were randomly assigned to splint group (n = 39) and control group (n = 41). The patients were classified in terms of depressive and non-specific physical symptoms as normal, moderate or severe using Research Diagnostic Criteria for Temporomandibular Disorders Axis II protocol. The effect of depressive and non-specific physical symptoms on the intensity of facial pain, as measured with visual analogue scale (VAS) was estimated with linear mixed models. The patients’ subjective estimates of the effects of treatment and TMD symptom severity were inquired at 1-year follow-up.

Results: At baseline and during the follow-up there were no significant differences in VAS scores between patients in different Axis II subscales. According to the mixed linear regression, depressiveness or nonspecific physical symptoms separately were not significantly associated with the VAS during the study. The association of VAS with depressive (p = .073) and nonspecific physical symptoms (p = .088) approximated statistical significance. Patients with moderate or severe nonspecific physical symptoms (with pain items) at baseline had more frequently moderate, severe or intolerable TMD symptoms after the treatment compared to those who were classified in normal subgroup.

Conclusions: The present study gave some indication of a possible negative effect of depressive and nonspecific physical symptoms (with pain items) on TMD treatment response. However, the results should be regarded as preliminary, and further studies with larger sample size are needed to confirm the results.
