Abstract

Introduction:Non-surgical retreatment is a conservative approach for managing recurrent endodontic infections requiring efficient removal of obturating material while preserving dentin. Retreatment file systems,through their design and function,plays a vital role in ensuring effective cleaning and minimal structural compromise.Methodology: Forty-five extracted mandibular molars were decoronated and obturated at a standardized root length of 16 mm in both mesial canals. Samples were divided into three groups (n=15): Group 1 – SoliteRS3, Group 2 – Dentsply Protaper Universal Retreatment Files and Group 3 – Neoendo Retreatment Files. Pre- and postoperative CBCT scans were used to assess remaining dentin thickness, canal centering ability and centering ratio.Data were analyzed using one-way ANOVA and post hoc Tukey tests (p<0.05).Results:There was a statistically significant difference among the three file systems in all evaluated parameters[pConclusion:SoliteRS3 files demonstrated superior dentin conservation and canal centering, making them a favorable choice for endodontic retreatment.
