Osteoporosis is a common metabolic disease characterized by low bone density. Menopausal women is more susceptible to osteoporosis due to decrease of estrogen secretion. Osteoporosis affects both trabecular and cortical bone. Mandibular bone density is an important determinant which plays a vital role in the success of mandibular dental implant and denture treatment. Mandibular bone density can be assessed using simple radiomorphometric index measurements on panoramic radiographs. The aim of this study is to determine the correlation between bone mass density which stated on BMD and T-score value with radiomorphometric index. Subjects of this study were Indonesian Javanese menopausal women, age 52-81 years. Examination of bone mass density at femoral neck and lumbar spine performed in the radiology installation of Dr Sardjito hospital, while panoramic radiographs were taken in the dentomaxillofacial radiology department of Prof Soedomo dental hospital, faculty of dentistry Universitas Gadjah Mada. Radiomorphometric index measurements made on panoramic radiographs that passed the radiographic quality assurance. The mental index (MI) and panoramic mandibular index (PMI) measurements was performed on 32 radiographs, while measurement of antegonial index (AI) and gonion index (GI) was performed on 34 radiographs. The statistical test of Pearson correlation showed significant correlation on positive direction between femoral neck BMD, lumbar spine BMD, femoral neck T-score, and lumbar spine T-score with MI (p <0.05, r = 0.415-0.436), AI ( p <0.01, r = 0.484-0.577), and GI (p <0.05, r = 0.614-0.681). While the results of Pearson correlation test showed no significant correlation between femoral neck BMD with MI (p<0,05). Spearman correlation test between femoral neck BMD, lumbar spine BMD, femoral neck T-score, and lumbar spine T-score with PMI showed significant correlation on positive direction (p<0.05, r = 0.358-0.433). The results of this study suggest that osteoporosis may affect mandibular bone density signed by thinning of mandibular cortical thickness as indicated by decline of radiomorphometric index equally with the decline of bone mass density on femoral neck and lumbar spine.
