In the practice of dentistry, cone beam computed tomography (CBCT) has been used in the indication of implants and maxillofacial surgery. In endodontics its use has already begun, because of the possibility to learn the three dimensions of the tooth. The aim of this study was to determine the frequency of various conditions that are the most prevalent in endodontics, using CBCT, for which they were identified and quantified radiographic findings of endodontic connotation in 128 CBCT in Chilean patients between 7 and 78 years old, of both sexes, evaluating a total of 1213 teeth. The images were obtained by SkyView 3D Panoramic CBCT Imager^® 12 bits (MyRay, Imola, Italy), with an exposure of 90 Kvp, 10 mA and observed by software Skyview viewer manager ver 1.2.0.6 MyRay by two previously calibrated observers. Teeth were observed in the sagittal, coronal and axial axes with a cutting interval of 0.5 mm. The data was introduced into" SPSS Statistics package for Windows, version 17.0) (SPSS Inc., Chicago, IL) for analysis. The findings of endodontic connotation were: apical lesion, endodontic therapy performed, taurodontism, accessory canals, dilacerations, open apices, internal resorption, cervical and apical external resorption). Significant association between the presence of endodontically treated teeth and apical lesions (p= 0.00) was found.
