CBCT Evaluation of Obturating Material Removal Using Reciproc And Protaper D Retreatment Kit in Root Canal and Efficacy In Removing The Obturating Material - In Vitro Study
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2019, Vol 4, Issue 7
Abstract
Aim: The Aim of the study is to evaluate the removal of obturating material removal using Protaper D, 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 Protaper D Retreatment 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 Protaper D Retreatment file. However the difference was not significant. Reciproc Blue provided cleaner canals in the apical region when compared to Protaper D.
