Abstract: The objectives were: (1)test accuracy of CT in detection of vertical root fracture and (2) investigate the influence of the metallic post in detection of vertical root fracture. Four teeth with vertical root fractures were selected and tested in four conditions determined by the presence or absence of metallic post and location of fracture. Two teeth without fracture were used as controls, one receiving metallic post. These teeth were inserted into a jaw and underwent a CT scan. The results were interpreted by ten radiologists by the presence or absence of fractures. The results showed an inconsistency in interpretation of fractures, having been found a greater number of false-positive results (10%) and false negatives (53.3%) that the accurate diagnosis of fractures (37.6%). Can still be seen less accurate diagnosis of these fractures in teeth that had metallic posts than in teeth that did not. © 2011 Sociedade Portuguesa de Estomatologia e Medicina Dentária.
