Background: Osteoporosis is a bone metabolic disease, characterized by decreased bone mass density and impaired micro-architecture of bone tissue, is seen commonly with increasing age. Mandibular inferior cortical shape and width on dental panoramic radiographs may be useful screening tools for osteoporosis. The aim of this study was to assess mandibular bone mineral density by using panoramic radio morphometric indices and determine the relation between theses indices with some serum biochemical markers. Materials and Methods: This study was enrolled forty-three post-menopausal women as a case group and thirty pre-menopausal women as a control group. Quantitative mandibular radio-morphometric indices include the Mandibular Cortical Index (MCI), the Mental Index (MI) and Panoramic Mandibular Index (PMI) which were measured on digital panoramic radiographs, and serum, calcium, phosphate, vitamin D, estradiol and parathyroid hormone levels were evaluated. Result: Two groups, 43 menopausal women (cases), and 43 premenopausal women (control). Around one third (32.6)) of cases have established osteoporosis (C3 category of MCI), compared with 0% of the control group (p < 0.001) which is highly statistically significant difference between the 2 groups, other panoramic indices do not show any statistically significant differences between the 2 groups, the mean of estradiol level among women of C3 category (5.42) is very low, compared with 70.88 among C1 women and 59.43 among C2 women (p < 0.001). other parameters do not show any significant differences between the 2 groups. Low levels of MI, IPMI, and SPMI is found among women of C3 MCI category, and all the differences between the MCI categories were significant (p= 0.021, p= 0.003, and p= 0.024 respectively Conclusion: The mandibular cortical index, and shape on the dental panoramic radiographs may be used as an indicator of bone turnover. In this study there is a correlation between estradiol and osteoporosis.
