Comparison of the Mandibular Bone Densitometry Measurement Between Normal, Osteopenic and Osteoporotic Postmenopausal Women

Objective: This study was conducted to compare the mandibular bone density be- tween postmenopausal women with normal skeletal bone mass density (BMD) and those with low skeletal BMD using digital panoramic radiographs. Materials and Methods: One hundred fifteen postmenopausal women were di- vided into normal and osteoporotic/osteopenic groups. Digital panoramic radio- graphs were prepared using Digora PCT Sorodex equipment and Promax pano- ramic X-ray unit (Planmeca, Helsinki, Finland, Kvp=68 and mA=9). The mandi- bular bone density of an area (approximately 4×4 mm), exactly near the distal edge of the right mental foramen was determined in digital panoramic radiographs using Digora for Windows (DfW) Software. Results: There was no statistically significant difference in mandibular bone den- sity between the normal and osteoporotic/osteopenic participants (P >0.05). Man- dibular bone density was not statistically different in normal and osteoporotic in- dividuals with SBMD or FBMD T-score -2.5 (P >0.05). Density of the region of interest differed significantly between the normal and the osteoporotic group with SBMD and FBMD T-score -2.5 (P <0.05). The same results also gained in women Corresponding author: L.

Conclusion: Mandibular bone density in subjects with low BMD was related to FBMD. So, digital panoramic radiographs could be beneficial in the diagnosis of postmenopausal women who are at risk of osteoporosis.
