“CBCT EVALUATION OF OBTURATING MATERIAL REMOVAL USING RECIPROC AND NEO-NITI RETREATMENT KIT IN ROOT CANAL AND EFFICACY IN REMOVING THE OBTURATING MATERIAL - IN VITRO STUDY”

Abstract

Aim: The Aim of the study is to evaluate the removal of obturating material removal using Neo NiTi, Reciproc Retreatment kit in root canal and Efficacy in removing the obturating material using CBCT.

Material & Method: Thirty extracted human single-rooted, verified radiographically teeth were selected and stored in a 0.1% thymol. Access cavity preparation was done and working length was determined by inserting a size 10 K file (Dentsply/Maillefer) into the root canal until it was visible at the apical foramen and subtracting 1mm from that length. Root canal preparation was done using ProTaper universal rotary files. All canals was prepared upto F4 ProTaper file. Irrigation was done after each instrument with 10mL of 2.5% NaOCl. Canals were then dried with paper point. The root canals were obturated with corresponding ProTaper gutta-percha cones with AH plus root canal sealer. The gutta percha was then removed using Reciproc retreatment files and NeoNiti files.

Result: There was significant difference in residual OM in the apical, middle and coronal areas between the two retreatment techniques (P<0.05).

Conclusion: Reciproc Blue retreatment instruments were more effective in the removal of filling material from the root canal than NeoNiti. However the difference was non significant. Reciproc Blue provided cleaner canals in the apical region when compared to NeoNiti.
