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.
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.
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.
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.
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.
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.
