Abstract

Aim: The present study aimed to assess the accuracy of CBCT for evaluation of 
maxillary bone density. Subjects & Methods: The study was conducted on twelve 
vitamin D deficient patients indicated for posterior maxillary rehabilitation. Patients 
were divided into two groups: Group A received vitamin    D and calcium supplement 
while Group B was a control group. First parameter was overall body bone density 
using Dual-energy X-ray absorptiometry (DXA) while second parameter was maxillary 
bone density using CBCT. Results: Group A showed a significant increase in vitamin D 
levels from 12.75 to 26.64 ng/ml (p < 0.05). this increase in vitamin D was accompanied 
by increase in bone density of spine from - 1.48 to - 1.08 T-score (p > 0.05). On the 
other hand, group B did not show similar improvements either at vitamin D or bone 
density of spine. Nevertheless, assessment of maxillary bone density using CBCT 
showed improvement in group B greater than group A. Conclusion: CBCT can be used 
as a relative rather than a reliable indicator of bone density
