The objective of this research is to examine the relationship between Bone Mass Density (BMD) and parameters from Panoramic Radiograph, including Panoramic Mandibular Index (PMI), Mental Index (MI) and Mandibular Cortical index (MCI). The subjects of this research consist of volunteers who participated in the Refracture Prevention Projects of osteoporotic patients with broken hip bones, who underwent surgical treatment and bone mass measurements. The patients were sent to the Dental Department to have Panoramic Radiograph taken, and based on the Radiograph, were measured the parameters PMI, MI, and MCI. The total number of patients in this research is 96, including 25 male and 71 female, aged from 53 to 103 years. The Pearson correlation analyses show that PMI and MI are not correlated with BMD. (p>0.05) The Analysis of Variance (ANOVA) results show that the differences in BMD among patients with different MCI values are statistically significant for the BMD at Total Femur and Spine locations, but not significant for the Total Body BMD. The Chi-square test also confirms the differences of BMD of patients with different MCI values. In conclusion, the results in this paper suggest that the screening of osteoporotic patients can be done with Panoramic Radiograph by using MCI values; however, PMI and MI values cannot be used for this purpose.
