Capacidad de adhesión y penetración del AH Plus ® vs BioRoot® visto con microscopía electrónica de barrido.

Abstract

The success of endodontic treatment depends on the preparation chemo-mechanical preparation and obturation of the root canal system. An ideal obturation must have a correct adaptation: fill the entire root canal system in a homogeneous and three-dimensional way. Objective: To determine the adhesion and penetration of Bioroot® cement compared to AHPlus® in endodontically filled teeth seen with scanning electron microscopy. Methodology: Quasi-experimental in vitro study consisting of 20 uniradicular teeth, which were prepared with Wave One Gold files, irrigating with 5.25% NaOCl between each instrument. The final irrigation was performed with NaOCl followed by 17% EDTA; For filling, 10 teeth were randomly selected for Group1: AH Plus® and single cone and 10 for Group 2: BioRoot® and single cone. The samples were sectioned at 4 and 8 mm and were observed under SEM Tescan Lyra. The images were measured with AutoCAD 2019. Results: BioRoot® presented higher penetration than AH Plus®. Being decreasing in the apical crown direction in both cements. Voids were observed at the dentin-cement interface, being smaller for AH Plus®. Conclusion: BioRoot® presented satisfactory penetration and adhesion, which makes it suitable for use in endodontic obturation.
