Apical microleakage comparison using various sealers and different obturation techniques- An in-vitro study

Abstract

The aim of the study is to compare the apical microleakage of two Bioceramic sealers Ceraseal, MTA Fillapex and an Epoxy resin sealer (AH Plus) with two different obturation techniques single cone and thermoplastic obturation techniques using dye extraction method. 80 mandibular single rooted premolars were decoronated, & biomechanically prepared. The samples were randomly divided into eight groups with ten samples (n=10). Group (A1) contained roots samples obturated with Ceraseal sealer and a single cone Gutta percha. Group (A2) constituted samples obturated using Ceraseal sealer and thermoplastic obturation. Group (B1) samples were obturated with MTA Fillapex sealer with a single cone. Group (B2) contained roots which were obturated using MTA Fillapex sealer with a thermoplastic obturation. Group (C1) contained roots samples obturated using AH Plus sealer with a single cone. Group (C2) samples were obturated using AH Plus sealer with thermoplastic obturation. Group D and Group E served as positive and negative control. Apical leakage was assessed using dye extraction method. Warm or cold obtuartion technique using sealers with different composition does not totally eliminate apical microleakage.
