Abstract
Objective. The purpose of this study was to determine if mandibular motion measurements could
be used to distinguish between common temporomandibular disorder (TMD) subgroups that
were established on the basis of only clinical signs and symptoms. Study Design. Patients were 41 consecutive TMD clinic patients (31 women and 10 men). These patients
were divided into 6 typical TMD subgroups. The subgroups were patients with (1) arthromyalgia,
(2) arthromyalgia with disk condyle incoordination, (3) disk condyle incoordination
only, (4) osteoarthritis, (5) suspected disk displacement without reduction, or (6)
other diagnoses. Results. There were no subjects in the other-diagnosis subgroup and only 1 subject with suspected
disk displacement without reduction who was dropped without further consideration.
The data for mean age showed that the osteoarthritis subgroup (n = 12) was statistically
older (17 years) than the disk-condyle-incoordination-only subgroup (n = 11). The
mean age of the other 2 groups, arthromyalgia (n = 11) and arthromyalgia with disk
condyle incoordination (n = 6), was between the osteoarthritis and the disk-condyle-incoordination-only
subgroups. For the 4 TMD subgroups whose data were analyzed, the mean differences
between similar jaw opening measurements ranged from 6 to 8 mm with a standard deviation
of approximately 8 to 10 mm. The mean left lateral motions were 0.5 to 1.3 mm larger
than observed on the right. The widest mean jaw opening (56 mm) occurred in the disk-condyle-incoordination-only
group. These differences were not found to be statistically significant. Conclusion. Analysis of opening, lateral and protrusive jaw motion data showed these measurements
could not reliably differentiate between patients with osteoarthritis, arthromyalgia,
arthromyalgia with disk condyle incoordination and disk condyle incoordination only.
