To compare the number of comorbidities and the prevalence of five specific comorbidities in people who have temporomandibular disorders (TMD) with or without myofascial pain.
This is a study
based on the lucid and eloquent comparison between people with myofascial vs
nonmyofascial temporomandibular disorders. Various tests performed showed the
superiority towards myofascial temporomandibular disorders for self-reported
migraine and chronic fatigue syndrome.
To compare the
number of comorbidities and the prevalence of five specific comorbidities in
people who have temporomandibular disorders (TMD) with or without myofascial
pain.
This
cross-sectional study included 180 patients seeking TMD treatment in Boston and
Montreal hospitals. A self-administered questionnaire was used to collect
information on sociodemographic and behavioral factors, as well as the presence
of the following five comorbidities: migraine, chronic fatigue syndrome,
irritable bowel syndrome, interstitial cystitis, and restless leg syndrome. TMD
was diagnosed using the Research Diagnostic Criteria for TMD. Chi-square and
Student t tests were used for categorical and continuous variables,
respectively, to test for differences between myofascial (n = 121) and
nonmyofascial (n = 59) TMD groups. Multiple logistic regression analysis was
used to compare the type and number of self-reported comorbidities in both
groups, controlling for confounding variables.
The following
were found to be significantly higher in the myofascial TMD group than in the
nonmyofascial TMD group: self-reported migraine (55% vs 28%, P = .001), chronic
fatigue syndrome (19% vs 5%, P = .01), and the mean total number of
comorbidities (1.30 vs 0.83, P = .01).
Individuals with
myofascial TMD had a higher prevalence of self-reported migraine and chronic
fatigue syndrome than those with nonmyofascial TMD.
