A cone beam computed tomographic evaluation of root canal treatment quality using periapical and endodontic status scale

Background: Cone beam computed tomography (CBCT) is a three-dimensional digital imaging which provides an image that can be viewed in multiple planes thus providing a better understanding of the anatomy of the root canal. Aim: This study aimed to evaluate the endodontic treatment quality of root-filled teeth and to determine the relationship between endodontic technical errors and complications. Materials and Methods: One hundred and fifty-two root canals were evaluated by CBCT from December 2017 to January 2019. Three endodontists assessed the root canals for the presence of technical errors and treatment complications using the periapical and endodontic status scale. Chi-square test and descriptive analyses were performed. Results: Sixty-one (40.4%) root canals had periapical radiolucency followed by 45 (29.8%) root canals with short obturations. Sixty-nine root canals (45.7%) and 45 (29.8%) root canals had nonhomogenous root canal filling and coronal seal (CS), respectively. Statistically significant association was seen with the length of the root canal filling, homogeneity, CS, and complications (P
