Background: The examination of Bone Mineral Density Distribution (BMDD) in human bone biopsies has propelled the comprehension of how bone turnover relates with different known pathologies and medications meant to improve bone density. Aim: To comparatively evaluate the cortical bone mass and cortical width at a standard site of the mandible with that in the iliac crest. Materials & methods: The present study included assessment of 30 cadavers who have died in recent past and have been deposited to the department of human anatomy. Specimen materials were extracted from lower jaw two mm anterior to the mental foramen. Width of the measurement and the mean cortical width (MCW) were obtained. Another set of two specimens was obtained in a similar way, as done in case of mandibular specimen, from the iliac crest.. All the results were analysed by SPSS software. Results: Mean bone mass observed in the subperiosteal and sub-endosteal layer of mandibular cortices was found to be 92.2 and 84.7 percent respectively. 88.2 percent was the mean bone mass observed in the entire cortical plate of mandibular cortices (Table 1). In the iliac crest cortices, the mean bone mass at sub-periosteal and sub-endosteal layer was found to be 86.6 and 82.6 respectively. The mean bone mass of the entire cortical plate in the iliac crest cortex was found to be 85.4 percent. Significant results were obtained while correlating the age and mean bone mass in the sub-periosteal and sub-endosteal cortex (P- value < 0.05). Conclusion: Iliac crest specimens cannot predict mandibular canal porosity.
