An evaluation of temporomandibular joint radiographs

Usefulness of tomography in the evaluation of patients with temporomandibular disorders: a retrospective clinical study

OBJECTIVES

To evaluate the effect of temporomandibular joint tomography on the diagnosis and management of temporomandibular disorders and to determine whether there were any clinical predictors of usefulness of tomography in providing new information helpful in the treatment of these patients.

STUDY DESIGN

The charts of 116 patients with temporomandibular joint tomograms were reviewed retrospectively for presenting signs and symptoms, initial clinical diagnosis, and alterations in diagnosis and management as a result of tomography.

RESULTS

Common clinical diagnoses included osteoarthrosis (54%) and internal derangement (42%). Tomography changed the diagnosis in 24%, mainly adding or subtracting osteoarthrosis, and altered the management in 17%. Most of the latter were minor changes in treatment recommendations. There were few clinical variables that were related to whether tomography changed diagnosis or management.

CONCLUSIONS

Tomography seems to have a minimal effect on the diagnosis or management of temporomandibular disorders based on the results of this retrospective study.

Report of the Committee on Scientific Investigation of the American Academy of Restorative Dentistry

Dental research continued to grow during 1988. Unfortunately the quality does not always parallel the quantity of publications. This report obviously does not encompass all of the literature but focuses on studies that are related to trends and to matters that are considered controversial. Likewise the particular interests of the members of the American Academy of Restorative Dentistry were taken into consideration. The subjects covered include periodontics, preventive dentistry, bulp biology, craniomandibular disorders, ceramics, color in restorative dentistry, and dental materials.
