Sažetak
This study was conducted to determine the relationship of the center of the mental foramen to the inferior (IM - CM) and superior borders (CM - SM) of the mandible, as reference points on panoramic radiographs in different groups according to sex, age and loss of teeth, to elucidate some of the factors contributing to alveolar ridge resorption. Measurements of 564 images (left and right sides) on 282 panoramic radiographs revealed the mental foramen to be nearer to the lower border of the mandible (p <0.05). There was no significant difference for IM - CM distances between the groups with different number of teeth and of different age in either men and women (p > 0.05), indicating this part of 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 of tooth preservation and suggesting the complete loss of teeth to be the main factor of alveolar bone resorption.
