Comparison of Retreatability of AH Plus Sealer and Bioceramic Sealer with Solvent, Retreatment Files and Diode Laser: A CBCT and SEM Analysis.

Abstract

Aim: The present study evaluated the retreatability of canals obturated using AH Plus sealer and Bioceramic (BC) sealers, employing Cone beam computed tomography (CBCT) and Scanning Electron Microscope (SEM).

Methodology: A group of 90 extracted premolars was classified into two main categories based on whether they were sealed with AH Plus or BC Sealer. Each of these categories was then divided into two subcategories according to the retreatment technique applied. CBCT and SEM were used to assess the residual filling material within the canals.

Results: The findings showed that there was no marked statistical variation in the retreatment success of canals sealed with BC and AH Plus sealers.

Conclusion: The diode laser was the most effective modality for eliminating root canal filling materials in the least amount of time. None of the retreatment modalities used removed the obturating material completely.
