Repeatability and effect of different voxel sizes on linear and volumetric tooth and pulp measurements using cone-beam computed tomography.

ABSTRACT:

Objective

In cone-beam computed tomography (CBCT), voxel resolution and size directly affect image quality. This study aimed to analyze the effect of voxel resolution on the linear and volumetric measurements of tooth and pulp in three-dimensional images obtained with different voxel sizes and to test the repeatability of these measurements.

Materials and methods

CBCT images of 30 extracted single-rooted permanent teeth were obtained using 3 different voxel sizes (0.1-, 0.2-, 0.4-mm). Two observers performed volumetric and linear measurements of pulp and teeth using semi-automatic segmentation. The data were analyzed using descriptive and nonparametric tests. For interobserver reliability, the Wilcoxon signed test and Kendall's tau correlation coefficient were used. The intr
