Possible Identification Marker in Orthopantomograms: Edentulous

The routine radiographic examination by orthopantomography of the jaws of all dental patients is necessary and justifiable. To evaluated the possible radiographical marker in edentulous for identification. To determine the age and gender from different parameters of radiographs. Study was conducted on 103 orthopantomograms of edentulous patients, aged (55-76 years). All radiolucencies or radioopacities in premolar to posterior alveolar ridge were observed. Different parameters such as; height of mandibular body, distance between lower mandible border to superior margin of mental foramina. The distance between the superior margin of mental foramina to crest of the alveolar ridge and the from the lower border to crest of alveolar ridge. Identification markers were found in 23.8 percent cases. Age was directly related to alveolar ridge in both males and females. Distance between crest of alveolar ridge and superior margin of mental foramina may be used for gender and sex determination.
