Summary: | Objective: This study evaluated the quality of root canal treatment (RCT) and determined the prevalence of apical periodontitis (AP) in Al-Madinah Al-Munawwarah, Saudi Arabia. Materials and Methods: Panoramic radiographs of 630 patients (316 males and 314 females) who attended clinics at the Dental College of Taibah University seeking dental care for the first time between 2010and 2013 were assessed for the adequacy of RCT and presence of AP. Results: RCT of at least one tooth was found in 52.8% of the patients, with a significantly higher prevalence in females (28.4 vs. 24.4%; P = 0.012), and AP was found in 53.5% of the patients, with a significantly higher prevalence in females (31.9 vs 21.6%; P = 0.000). Conclusions: There was a significant correlation between AP and inadequate endodontic treatment. This study reveals the importance of improving RCT in Al-Madinah Al-Munawwarah.
