Abstract

Objective: The aim of this study was to compare, by means of three-dimensional reconstructed images, the validity of multislice computed tomography (MSCT) and cone-beam computed tomography (CBCT) in the diagnosis of simulated mandibular lesions. Methods: Fifteen dry mandibles were perforated using a round bur (diameter of the tip: 1mm) and a high-speed handpiece. The lesions, which differed in dimension, shape and locularity, were produced either in the buccal or lingual cortical bone of the mandibular body. In some cases, the bur just touched the cortical bone, whereas in others, it perforated the medullary bone. Specimens were submitted to CBCT and MSCT. The images were analyzed independently by two experienced examiners using commercially available software (Vítrea®, version 3.4.5; Vital Images Inc., Plymouth, MN, USA) at different sessions according to two protocols: 3D reconstruction of MSCT scans (3D-MSCT) and 3D reconstruction of CBCT scans (3D-CBCT). Results: There were no significant differences between the two protocols regarding the identification of medullary bone involvement or the number of lesions detected. Conclusion: The validity of 3D-CBCT for the identification of the number of lesions and of medullary bone destruction was similar to that of 3D-MSCT.
