INTRODUCTION Bioactive endodontic sealers have been developed to improve the quality of root canal obturation. EndoSequence Bioceramic (BC) Sealer is amongst calcium silicate-based materials recently developed for permanent root canal filling. The objective of this study was to evaluate the bioactivity of BC Sealer and its micro push-out bond strength to dentin compared to AH-Plus (AH) sealer. ...

in order to deermine the effect of root canal cealer on microleakage of obturated root canal by lateral condensation technique(LCT) with and without tug-back(TB).seventy exteracted single root canal teeth were examined.after preparation of root canal with step-back technique,teeth were divided to six groups as follows:5 teeth as positive control group that obturated by LCT with gutta-perch itho...

INTRODUCTION Sealers based on tricalcium silicate cement aim at an interaction of the sealer with the root canal wall, alkalinity with potential antimicrobial activity, and the ability to set in a wet field. The aim of this study was to characterize and investigate the properties of a new tricalcium silicate-based sealer and verify its compliance to ISO 6876 (2012). METHODS A new tricalcium s...

Aim: The purpose of the study was to compare the apical seal produced by Zinc oxide eugenol sealer, calcium hydroxide based sealer (Metapex), Glass ionomer root canal sealer (Ketac Endo) and epoxy resin root canal sealer (AH Plus). Materials and methods: Biomechanical preparation using step back technique and irrigation with 5.25% sodium hypochlorite was done on 120 extracted, single rooted, no...

The purpose of this study was to observe the influence of coronal leakage on the behavior of periapical tissues after root canal filling and post space preparation. Forty root canals of dogs' teeth were instrumented and filled by the lateral condensation technique with gutta percha points and the cements Sealer 26 and Roth. After post space preparation, the remaining filling material was either...

Introduction: This study aimed to compare the fracture resistance using a bioceramic sealer and an epoxy resin-based sealer. Materials Methods: One hundred maxillary central incisors were randomly assigned three experimental groups: AH Plus single-cone technique, lateral compaction SureSeal Root sealer, two positive negative control groups. Then of prepared tooth roots was determined. The data ...
