Evaluation of the periapical condition of endodontically treated teeth by cone beam computed tomography

Resumo

Cone Beam Computed Tomography has become an important part of endodontic practice as it allows the visualization and manipulation of three-dimensional images. The present study aimed to evaluate the periapical condition of endodontically treated teeth through the analysis of computed tomography scans. This is a retrospective cross-sectional study in which 707 teeth were analyzed. The different dental groups, the presence of an intraradicular retainer, coronary restoration, root fracture, and root resorption, as well as the apical and lateral limits of the filling and the quality of the filling, were evaluated. The data were tabulated and then statistically treated through descriptive analyses and associations. The Kolmogorov-Smirnov and chi-square tests were used, and the significance level was 95% (p≤0.05). Of the total number of teeth analyzed, the maxillary incisors were the most prevalent (27.7%), followed by the maxillary premolars (18.8%) and the mandibular molars (15.1%). Significant associations were observed between the presence of alterations in the periapex and the apical limit (p=0.001), the lateral limit of the filling (p=0.000), the quality of the filling (p=0.030) and the presence of root resorption (0.000). It is concluded that unsatisfactory filling of root canals is a relevant factor for the presence of periapical diseases.
