Abstract

Aim:The aim of this study is to evaluate the cleaning efficiency of two rotary retreatment instrumentation techniques and Hand instrumentation technique (H file with solvent) in removing obturating material from the root canal walls, during retreatment procedure using scanning electron microscope.

Material and Methodology: A total of 45 human mandibular Premolar teeth with straight root canals were selected and the coronal one third enlarged with one flare. The biomechananical preparation of the teeth were done till F1 size ProTaper universal rotary file and gutta-percha and AH Plus sealer is used for obturation performed by lateral condensation technique. The samples were divided into three groups according to the retreatment system Group I- H File with solvent, Group II- ProTaper universal retreatment file system and Group III-WaveOne gold primary File. For the evaluation of residual materials, the buccolingually sectioned tooth samples were observed under scanning electron microscope. The statistical analysis of the data was obtained using one way ANOVA and Independent t- test.

Result: The highest amount of remaining filling materials was observed in the apical third followed by middle third and coronal third. WaveOne Gold primary file which works in reciprocating motion showed superior cleaning efficiency than ProTaper universal rotary system which works in continous motion and manual H file with solvent.

Conclusion: None of the system was able to remove obturating material completely. The efficiency of reciprocating files shown to be superior in removing the filling material compared to continuous retreatment system. The least cleaning efficiency is exhibited by H file with solvent group in removal of root canal filling material.
