BACKGROUND: There is a need for clinical tests that can reveal intra-articular conditions in the temporomandibular joint to be able to give proper treatment. The Dental stick test, where participants bite with their molars on a wooden stick, is a pain provocation test for the temporomandibular joint.
OBJECTIVE: The purpose of this study was to explore if the Dental stick test can be used to reveal intra-articular conditions in the temporomandibular joint in persons with long-lasting painful disorders.
DESIGN: Cross-sectional.
MATERIALS AND METHODS: Forty persons with pain in one or both temporomandibular areas were examined using the Dental stick test. The participants were between 18 and 70 years, and had 65 symptomatic joints. Sensitivity, specificity, false positive and false negative responses, and area under the curve were calculated for the Dental stick test with MRI and/or CT as reference standards. The phi-correlation coefficient (phi) was used to measure the correlation between the Dental stick test and intra-articular findings.
RESULTS: The sensitivity and specificity for the Dental stick test, revealing intra-articular findings, were 0.62 and1.0 respectively. False positive and false negative responses were 0 and 0.41 respectively, and the area under the curve 81% with p < 0.001. The correlation between a positive Dental stick test and intra-articular findings was not significant (phi = 0.60).
CONCLUSIONS: When the Dental stick test is positive, intra-articular findings will most probably be present on MRI/CT, but the test alone cannot reveal intra-articular conditions in persons with long-lasting painful temporomandibular disorder.
