Abstract

Objectives

The purpose of this study was to verify whether application of a quantitative computed tomography (QCT) technique was helpful for quantitative measurement of bone density using dental cone-beam CT (CBCT).

Methods

The left mandible of an opened-mouth head phantom was scanned with a dental CBCT machine at several tube voltages. A bone mineral contents phantom consisting of 20 blocks was used to provide the reference materials for the QCT technique. To investigate the effect of the number of reference materials used, three, four, or five blocks (reference blocks) were selected from the 20 blocks. The reference blocks were affixed to the surface of the lower jaw of the head phantom. Measurements of bone density were performed against another selected block (target block) set inside the oral cavity of the head phantom. The voxel values of the reference blocks and the target block on the obtained images were measured. The voxel values for the reference blocks were used to produce conversion curves. The density of the target block was calculated using each conversion curve.

Results

The conversion curves and voxel values of the target block were markedly and irregularly affected by the tube voltage and number of reference blocks. The error rates with three, four, and five reference blocks varied 4.1–11.0, 1.5–4.6, and 3.4–8.4 %, respectively.

Conclusions

Reference materials usage influences CBCT images in a non-uniform manner, and application of a QCT method does not aid quantitative measurement of bone density using dental CBCT.
