The efficacy of different instruments combined with Nd:YAP in endodontic retreatment.

ABSTRACT:

Background

To evaluate the efficiency of endodontic retreatment using different instruments and observe whether the Nd:YAP laser can assist.

Methods

Eighty premolars were selected, of which the root canals were prepared, and were filled with both gutta-percha and AH plus. The teeth were randomly divided into eight groups, respectively using and not using the Nd:YAP laser with the use of H files, Reciproc files, Mtwo R files, and Mtwo R + H files to remove the root-canal filling material. The retreatment time of each sample was recorded, and the amount of residual gutta-percha was calculated by Image J.

Results

(I) In the four no-Nd:YAP laser groups, the Mtwo R group and Reciproc group took the least time, and there was no statistical difference between them (P>0.05).
