EVALUATION OF CHANGES IN THE MANDIBULAR ANGULAR CORTEX USING PANORAMIC IMAGES IN OVER 20 YEARS OLD WOMEN (2001-02)

Introduction: Osteoporosis is a major problem of the elderly, especially in post menopausal women. Aim of this study was to evaluate bone resorption (BR) in women older than 20 years. Methods: One hundred women were assessed using an anatomic landmark of mandible (i.e. thickness of mandibular angular cortex, TMAC). Results: Results showed that BR had a positive significant relation with age and multiple pregnancies, and a negative relation with the level of education (p<0.001). BR in menopausal women was significantly higher than that in women of reproductive age (1.83 + 0.81 & 3.13 + 1.4,p<0.0001, respectively). Also, women with history of backaches had higher BR than women without backaches (1.58 + 0.54 & 3.08 + 1.4, p<0.0001, respectively). Conclusion: From these results, it could be concluded that thickness of mandibular angular cortex can be used as an index for BR.
