Comparison of Retreatability of two endodontic sealers, AH plus resin based and AH plus BC Sealer: a micro-computed tomographic comparison.

Abstract

Aim and Objectives: Aim of this study was to compare and evaluate the retreatment 
efficacy of two endodontic sealers, resin based and calcium silicate based: Micro Computed 
tomographic comparison.
Materials and Methods: Fifty-six extracted human maxillary incisors were 
instrumented and randomly divided into 4 groups of 14 teeth: 
1. Subgroup 1A, gutta-percha, AH Plus resin based sealer retreated with chloroform.
2. Subgroup 1B, gutta-percha, AH Plus resin based sealer retreated without chloroform.
3. Subgroup 2A, gutta-percha, AH plus bioceramic sealer retreated with chloroform.
4. Subgroup 2B, gutta-percha, AH Plus bioceramic sealer retreated without chloroform.
