Comparison of artifact values of prosthodontic materials with 2 different cone beam computed tomography devices
Özet
Statement of problem: Prosthodontic materials may cause unexpected artifacts in cone beam computed tomography (CBCT) images, but studies quantifying these artifacts are sparse. Purpose: The purpose of this in vitro study was to compare the artifact expression of fixed prosthodontic materials with different CBCT devices. Material and methods: Ten prosthodontic materials (Co-Cr-Mo alloy, interim acrylic resin, polyetheretherketone, feldspathic ceramic, lithium disilicate glass-ceramic, zirconia-reinforced lithium silicate ceramic, zircon core, and 3 monolithic zirconias) were scanned with 2 CBCT devices. The materials were placed in polymethyl methacrylate resin to simulate clinical conditions. To assess the impact of the devices on artifacts, the gray values of 8 areas in each material image were analyzed. The data were analyzed with the Kruskal-Wallis and Wilcoxon Signed-Rank tests (α=.05). Results: Statistically significant differences were found in the artifact expression of the materials (P<.001) and between CBCT devices (P<.001). Conclusions: The artifact expression of polymeric and ceramic materials in CBCT images was less than that of other materials. The milliampere-second (mAs) value of CBCT devices had a significant impact on the artifact level.
