Painful sensitivity to palpation in patients presenting with chronic temporomandibular dysfunction
Keywords:
facial pain, temporomandibular joint, headaches.Abstract
The cephalalgias are frequently associated with the temporomandibular disordersbeing common to find an increase of pain sensitivity in these patients. Thus, the
objective of present study was to assess the sensitivity to palpation in patients
presenting with chronic temporomandibular disorders comparing two groups one
with headache and other without it, respectively. The temporomandibular disorders
and the primary cephalalgias were diagnosed according the Diagnostic Criteria for
the Research of Temporomandibular Disorders and by a questionnaire based on the
International Classification of the Cephalalgias (2004). Location, assessment and
grouping of muscular and articular areas for palpation were carried out according to
the Diagnostic Criteria for above mentioned disorders, considering bilaterally the
masseter muscle, the temporalis muscle, the cervical region and the
temporomandibular joint. Sample included 213 (88.0 %) of women and 29 (12.0
%) men with a mean age of 37.41 years. The mean of number of zones positive to
palpation in the groups without headaches, tension headache, migraine and daily
chronic headache were: 12.43, 14.38, 15.21 and 15.62 (p= 0.107) (min 2 max
22). The areas of temporalis muscle showed significant differences among groups
(p= 0.007). The number of painful points was not statistically different among
groups and only in the temporalis muscle there were differences with statistical
significant to palpation.
