Introduction: sacrum is an important bone for identification of sex of an individual by using skeletal material among anatomist, anthropologist and forensic experts. Aim: to find out diagnostic efficacy of sacral index and Kimura’s base wing index methods of sex determination of sacrum. Material and method: 100 fully ossified adult sacrum of known sex were used and data were collected by using vernier caliper. Both sacral index and Kimura’s base wing index methods of sex determination were applied and analyzed by using Z-test. Conclusion: The results were compared with the available literatures and it was found that sacral index is more reliable than Kimura’s base wing index for establishing sex of a sacrum.
