This study was conducted to determine the relationship o f the center o f the mental foramen to the inferior (IM - CM) and superior borders (CM - SM) o f the mandible, as reference points on panoramic radiographs in different groups according to sex, age and loss of teeth, to elucidate some o f the factors contributing to alveolar ridge resorption. Measurements o f 564 images (left and right sides) on 282 panoramic radiographs revealed the mental foramen to be nearer to
the lower border o f the mandible (p <0.05). There was no significant
difference for IM - CM distances between the groups with different number o f teeth and o f different age in either men and women (p > 0.05), indicating this part o f the mandible to remain relatively constant in size, despite increasing age, loss of teeth and occurrence
of postmenopausal osteoporosis in women. In women the mandible was found to be significantly smaller for both measured distances (IM - CM, and CM - SM) than in men (p < 0.01), which was an expected finding, as women in general have smaller skeleton. In CM - SM measurements there was a significant difference (p < 0.01) between the dentulous and fully edentulous groups in both men and women, indicating the importance o f tooth preservation and suggesting the complete loss o f teeth to be the main factor o f alveolar bone resorption.
