Background: Clinical problems of the temporomandibular joint
(TMJ) and the masticatory musculature are both included in
the term temporomandibular disorder (TMD). The field of TMD
is well known for being one of the more controversial topics in
dentistry. Studies show a marked difference in the prevalence
of TMD from 16 to 64%. The purpose of the present study was
to examine whether patients with clinical TMD had pathological
findings utilizing magnetic resonance imaging (MRI).
Material & Methods: The study population consisted of 64
patients with clinical TMD. Symptoms were recorded using
a questionnaire, clinical examination included diagnosing
occlusion in centric relation, and then a standardized MRI was
performed. The images were read, utilizing the Piper system by
the treatingdentist and then readby twoexperienced radiologists
blinded to clinical data.
Results: All patients hadmolar interferences in centric occlusion
and limited anterior guidance. The patients also had changes
in disc position when examining the MRI scans. 68 of the joints
(55%) had changes corresponding to Piper IVa classification.
It was also found more severe changes like disc degeneration,
changes in condylar head, abnormal reduction and restriction
in anterior movement. The most severe changes were
corresponding to Piper Va and Vb (34 joints, 27%).
Conclusion: All the patients assessed due to TMD showed
changes in their TMJ on MRI. We also found posterior
interferences in their occlusion and loss of anterior guidance.
