Due to the short-comings of current dental imaging methods, represented by conventional radiographs, the researchers were looking for more efficient ways for dental evaluation. The Cone-beam computed tomography (CBCT) is now considered to be a next major achievement in dental imaging, with a wide range of indications at a lower cost and radiation dose compared to conventional computed tomography. The aim of our study is to evaluate the importance of CBCT scans in the assessment of endodontic pathology by comparison with the conventional radiography. The examinations were carried out on 27 patients with 35 root filled teeth in which the quality of the root filling, missed canals or persistence of apical periodontitis were recorded. The results showed a higher percentage of healed periapical lesions when the evaluation was carried out by conventional radiographic examination compared to CBCT (p <0.05). CBCT proved extremely efficient in endodontic therapy regarding the identification of anatomic variations and number of lesions per root canal (p < 0.05). CBCT examinations must be taken into consideration for cases in which the benefits of this investigation overcome the risks, offering additional information compared to conventional radiographic examination..
