Diagnostic efficacy of TMJ lateral linia tomographic image by multifunctinal panoramic tomography equipment

Abstract

The purpose of this study was to evaluate the diagnostic efficacy of TMJ lateral linia tomographic image for surveying the osseous changes in the TMJ disorders.
The subjects were some kinds of selected radiographs from 25 patients (50 joints) suspected TMJ disorders. They were refferred to Nihon University Dental Hospital, and taken ordinary panoramic radiograph, oblique transcranial radiograph and TMJ lateral linia tomograph at the Radiology Section.
The evaluation of the osseous changes in each radiographs was based on the evaluation with each arthrotomographs which were taken later.
In the result, panoramic TMJ lateral linia tomographic image showed better accuracy and sensitivity compared with ordinary panormic image and oblique transcranial image.
