Abstract: The aim of this study was to evaluate the accuracy of cone beam computed tomography (CBCT) for measurement of the volume, area and bone density of periapical lesions.50 CBCT-images from patients with endodontic treated teeth with periapical lesions were examined. The software for the images which was used is Planmeca Romexis. The results showed that the root canal filing quality is extremely important and influences both volume of the lesion and bone density.
