Aim and Objectives: The main objective of the study was to assess mandibular bone changes in individuals with chronic generalized periodontitis of different age groups, using radio morphometric indices such as mandibular cortical index (MCI), mental index (MI), and panoramic mandibular index (PMI) in Indian population from dental panoramic radiographs.

Materials and Methods: Panoramic radiographs of 60 patients with chronic generalized periodontitis visiting the Department of Periodontology, Rajarajeswari dental college and hospital, Bangalore were taken and divided into two age  groups. Group 1 included patients in the age group of 30–44 years and group 2 with an age range of 45–60 years. All the radiographs were assessed for PMI, MI and MCI and presence of periodontitis.

Results: Slightly higher mean values for PMI were observed in group 1 than group 2 whereas MI showed greater value in group 2. However, the differences in both groups were not statistically significant. MCI when compared between groups, C2 and C3 values were higher in group 2 suggestive of higher risk for osteoporosis with advancing age.

Conclusions: Radio morphometric indices could be used by general dentists to detect patients at higher risk of osteoporosis
