Descripció:This study aimed to assess the relationship of periapical (PA) radiolucencies with the quality of root canal treatment (RCT) using cone-beam computed tomography (CBCT) scans of an Iranian population. This cross-sectional study was conducted on 200 endodontically-treated teeth on CBCT scans retrieved from a radiology clinic in Qazvin, Iran. The sagittal, coronal, and axial views were evaluated by an endodontist and a trained senior dental student for root canal procedural errors and presence/absence of PA radiolucency in the respective teeth. The association of PA lesions with age, gender, jaw, tooth type, presence/absence of coronal restoration, and RCT quality was analyzed by the logistic regression model (alpha=0.05). The frequency of poor-quality RCT was 75.3% in teeth with a PA radiolucency, and 15.5% in teeth without it. A significant association was found between the quality of RCT and PA radiolucencies (P<0.001). Absence of coronal restoration also had a significant association with the presence of PA radiolucencies (P<0.001). Of the procedural errors, perforation, under- and over-obturation, low obturation density (voids), and canal transportation were significantly associated with the presence of PA radiolucencies (P<0.05). The RCT quality had a significant association with development of PA radiolucencies, such that procedural errors and absence of coronal restoration were associated with a significantly higher frequency of PA lesions.
