Objective: To determine the grayscale value (GSV) of three coronary dental filling materials using Cone-Beam Computed Tomography (CBCT). Materials and methods: six pig heads were selected and a restoration in tooth 72 was performed using one of the following materials: amalgam, composite resin, or Cention N®, obtaining two samples of each material. Two CBCT acquisitions were acquired for each specimen, one with a small field of view (4x4cm( and one with a large field of view (8x8cm), with fixed exposure parameters (90kV, 5mAs), for a total sample of 12 CBCT volumes. The GSV for each material was registered. Results and conclusions: It was observed that the average DGSV was 27 929.85 for amalgam, 5 798.54 for composite resin, and 5 885.47 for Cention N®. Although there is a variation in the VDEG of each material when the field of view is modified, this difference was not statistically significant.
