Effects of edentulism on mandibular morphology: evaluation of panoramic radiographs.

Purpose: The objective of this study was to evaluate morphological changes of the mandible in edentulous and dentate subjects using panoramic radiographs.

Materials And Methods: Panoramic radiographs were divided into the following three groups: Group I (completely edentulous group), Group II (old dentate group) and Group III (young dentate group). The research parameters of gonial angle, condylar height, ramus height, ramus notch depth, and antegonial notch depth were measured on panoramic radiographs.
