Comparing Success of One-Visit Versus Two-Visit Non-Surgical Root Canal Retreatment for Endodontic Disease

What this Trial Is About

Researchers are evaluating the success rate of non-surgical root canal retreatment performed in one visit compared to two visits in patients with periapical disease who require retreatment due to endodontic failure. This randomized controlled study aims to determine if there is any significant difference in treatment outcomes over a follow-up period of up to 10 years. The study is led by Universitat Internacional de Catalunya and focuses on endodontic diseases including root canal infection and endodontically treated teeth. Participants will receive non-surgical root canal retreatment either in a single visit or two separate visits. The study groups are randomized and treatment is administered by dental professionals following standardized procedures. The study monitors patients immediately after treatment and at several intervals up to 10 years to assess both clinical signs and radiographic evidence related to periapical disease. During the study, participants will be assessed for post-operative pain at various times immediately, 4 hours, 24 hours, and 48 hours after treatment. Clinical symptoms and radiographic changes related to apical periodontitis will be evaluated at 1, 2, 4, 6, and 10 years. Researchers will also study correlations between prognostic factors and clinical outcomes. Safety and treatment success will be monitored over the long term, requiring participants to attend scheduled follow-up visits throughout the study period.
