OBJETIVE: Assess the use of computed tomography for the diagnosis of vertical root fractures. METHODS: Ten extracted human teeth with vertical root fractures without separation of the fragments were used. The teeth were washed with a 5% sodium hypochlorite solution and cleaned with periodontal curettes to remove dirt. Root cracks were made according to the methodology described by Fachin & Aun¹ and Aun & Silva². The teeth were then placed in a dry skull for taking the periapical radiographs using the parallel technique. For the radiograph using the parallel technique, a Hanshin mounting frame for radiographic films was attached to the skull with an adhesive tape. The tooth was then subjected to computed tomography. The images were analyzed by three endodontists and two radiologists for comparison of the techniques. RESULTS: Assessment of root radiographs allowed detection of only one of the fractures. On the other hand, fractures were detected in all teeth when computed tomography was used. CONCLUSION: Computed tomography is not only widely used in implantology, but is also the method that best allowed the diagnosis of vertical root fractures. In addition to detecting the fractures, it was also possible to determine their location and size.
