AB  - The decrease of bone strength on ageing is a globally observed phenomenon among all human beings. The association between oral health and bone health has not been much researched among the Indian population. So, the proposed study was aimed to extract information about mandibular indices from dental panoramic radiographs and to identify its age and gender related changes among the south Indian population. The study involved 279 subjects, which included 103 men (46±11.55 years) and 176 women (47.2±12.49 years). The panoramic radiographs were obtained from a digital orthopantomogram scanner. The subjects were categorised into various decade age sub-groups for both the genders: 31-40, 41-50, 51-60, 61-70 and 71-80 years. The subjects were also further classified into three groups as: Normal, mild and severe based on the erosion of the endosteal margin of mandible cortical bone. The measurement of the Mandibular Cortical Thickness (MCT), Panoramic Mandibular Index (PMI) and assessment of the endosteal margin of the mandibular cortical bone was performed on the radiograph. The ANOVA test revealed a statistically significant difference for the MCT and PMI as (F = 6.98; p
