Key take away

This work is persuasive in explaining the characteristics of headaches concerned with temporomandibular disorders (TMD). The role of counseling and behavioral management of masticatory myofascial pain to deal with headache was also appreciated. 

Background

To describe the characteristics of headaches attributed to temporomandibular disorders (TMD) and assess the effects of two management strategies used for the management of TMD on headache intensity and frequency.

Method

The initial sample (n=60) of this randomized controlled trial comprised patients with masticatory myofascial pain according to the Research Diagnostic Criteria for TMD (RDC/TMD), and headache. The patients were divided into two groups: group 1 received only counseling for behavioral changes, and group 2 received counseling and an occlusal appliance. A 5-month follow-up period included three assessments. TMD-related headache characteristics, e.g., headache intensity (scored on a visual analog scale [VAS]) and frequency were measured by a questionnaire. Two-way analysis of variance, chi-square, Friedman, and Mann-Whitney tests were used to test for differences considering a 5% significance level.

Result

The main clinical features of headache attributed to masticatory myofascial pain were the long duration (≥4 hours), frontotemporal bilateral location, and a pressing/tightening quality. Forty-one subjects (group 1, 17 subjects; group 2, 24 subjects) were included in the final analysis. There was a reduction in headache intensity and frequency, with no significant differences between groups (P>.05). The mean (±SD) baseline VAS was 7.6 (±2.2) for group 1 and 6.5 (±1.6) for group 2; final values were 3.1 (±2.2) (P<.001) and 2.5 (±2.3) (P<.001), respectively.

Conclusion

Headache attributed to masticatory myofascial pain was mainly characterized by long duration, frontotemporal bilateral location, and a pressing/tightening quality. Also, counseling and behavioral management of masticatory myofascial pain improved headache, regardless of the use of an occlusal appliance.
