Outcome of Nonsurgical Root Canal Retreatment of Teeth with Persistent Apical Periodontitis Treated with Foraminal Enlargement and 2% Chlorhexidine Gel: A Retrospective Cohort Study

CE Hours: 1.0

Description: Nonsurgical root canal retreatment (NS-RCRT) becomes necessary when primary endodontic procedures fail. This study evaluates the efficacy of NS-RCRT using 2% chlorhexidine gel and foraminal enlargement techniques, aiming to assess whether these approaches enhance periapical healing outcomes and success rates compared to traditional NS-RCRT techniques reported in the literature.

At the conclusion of this article, the reader will be able to: 

• Evaluate the impact of foraminal enlargement on periapical healing outcomes in nonsurgical root canal retreatment (NS-RCRT). 
• Discuss the clinical implications of using 2% chlorhexidine gel as the primary irrigant in NS-RCRT. 
• Identify factors influencing the success rates of NS-RCRT based on the findings from the retrospective cohort study.
