The prevalence of some joint disorders in craniomandibular disorder (CMD) and bruxers as compared to CMD nonbruxer patients and controls.

Abstract

The objective of this study was to assess and compare the frequency of some joint disorders in 130 CMD + bruxing behavior patients, 66 CMD/nonbruxing behaviors patients referred for diagnosis and treatment to the Center for the Study of Craniomandibular Disorders and 130 control subjects seeking routine dental care. Both patients and controls were consecutive referrals to the clinic occurring over a five year period. The mean age of the CMD + bruxing behavior group was about 35.48 years (range 14-54, SD = 8.45), and 36.84 years (range 17-60, SD = 9.30) in the 66 CMD nonbruxing behavior group, and 34.34 years (range 14-62, SD = 9.92) in the control group of 130 subjects. Information gathered included a questionnaire, history of signs and symptoms, and a clinical examination. Different types of joint disorders, muscle signs and symptoms and bruxing behavior were assessed in the CMD groups and in the corresponding control group. The study concluded that capsulitis/synovitis, retrodiskal pain and disk-attachment pain predominated in CMD + bruxing behavior patients. The data reinforces the need to assess CMD + bruxing behavior patients to evaluate signs and symptoms of such disorders in order to obtain additional information about the true source of pain and the need for proper management.
