Non-surgical Root Canal Retreatment: A Retrospective Outcome Study

Journal Title: Meandros Medical and Dental Journal - Year 2020, Vol 21, Issue 1

Abstract

Objective: When the prognosis of a root canal treated (RCT) teeth is poor, retreatment (RT) of the former RCT is indicated. The aim of this study was to assess the long-term success rate of nonsurgical retreatment for five years. Materials and Methods: RTs were performed on 132 patients in 2013-2014; after drop-outs, 83 patients were enrolled clinically and radiographically after 5 years. The parallel-cone technique was used with a film holder, and radiographs were saved in JPEG format for further evaluation. In addition, intra-oral examinations were performed for RTs at 6 months and 1 to 5 years. Results: After 5 years of follow-up, only 83 of the 132 patients could be reached and assessed. Following RTs, 10.8% (n=9) of the patients were symptomatic on percussion, 6.2% (n=5) patients had sinus tracts with different diameters, 83% (n=69) of the patients were accepted as "healed teeth", and 17% (n=31) patients were accepted as "unhealed". When the quality of the root canal obturation after RT was evaluated, the number of root canal obturations short of the working length were evaluated. 84.3% of the root canals were accepted as "good" and 15.7% of the others were accepted as "short" root canals. Conclusion: Providing the proper working length may help to eliminate residual bacteria in the untouched regions and improve the quality of the new treatment for tooth survival in regard to better disinfection.
