,, Ĭonventional and digital periapical radiography (DPR) and panoramic radiography are typically used to diagnose radicular changes. Clinical signs and symptoms of VRF are not pathognomonic of the condition and its prognosis is poor.

, The diagnosis of VRF is difficult and imposes a challenge for the treatment planning. Compression on lingual and/or buccal aspect leads to separation of the root into two or more fragments. VRF are caused by impact of great strength. Early imaging diagnosis is essential since the stimulus that causes resorption must be removed as soon as changes are observed. ERR in the permanent dentition usually results of trauma, orthodontic movements, tumors, and eruption of teeth. , ĮRR has a complex etiology and its classification depends on the location and stimuli that induce its development. Usually an iatrogenic and undesirable incident, RP may occur at any stage of endodontic treatment and represent 10% of endodontic failures. Root perforation (RP) is a communication between the root canal system and the external root surface. However, despite the advancements in the area, the diagnosis of some radicular changes, such as root perforation, external root resorption (ERR) and vertical root fractures (VRFs), can still be a difficult task for dentists. , ĭental radiology offers several imaging methods to examine anatomical and pathological details during treatment planning. The diagnosis of radicular changes is a challenge in dentistry, one that requires imaging techniques that allow observation not only of the tooth in question but also of the adjacent bone structures. Comparison of diagnostic accuracy of root perforation, external resorption and fractures using cone-beam computed tomography, panoramic radiography and conventional & digital periapical radiography.

So for, RP indicate the conventional periapical radiography because CBCT has a higher radiation dose. CBCT and conventional periapical radiography obtained similar results for the evaluation of RP. The diagnosis of ERR was the least accurate, panoramic radiography being not appropriate for its diagnosis. The worst Az values for RP, ERR, and VRF (0.718, 0.494, and 0.611, respectively) were for panoramic radiography.Ĭonclusions: CBCT showed the best results in the diagnosis of ERR and VRF. Results: Receiver operating characteristic (ROC) revealed that CBCT showed the highest area under the ROC curve (Az) values for RP, ERR, and VRF (0.903, 0.950, and 0.849, respectively). The images were evaluated by 6 dentomaxillofacial radiologists. RPs were performed using diamond burs, ERRs using spherical carbide burs, and RFs using a universal machine EMIC-DL 1000. Materials and Methods: The sample consisted of 40 extracted human teeth and 10 macerated human mandibles. Is it worth doing CBCT despite the radiation dose?Īims: To evaluate and compare the diagnostic accuracy of CBCT, panoramic radiography, and conventional and DPR in the diagnosis of root perforation (RP), ERR, and VRF. This study aims to facilitate it by comparing the diagnostic accuracy of cone-beam computed tomography (CBCT), orthopantomography, and conventional and digital periapical radiography (DPR) in the diagnosis of such problems.
