INTRODUCTION The aim of the present study was to investigate and compare the apical sealing ability of Resilon/Epiphany-filled root canals with those that were obturated with gutta-percha/AH-Plus endodontic sealer. MATERIALS AND METHODS A total of 60 extracted human single-rooted teeth were selected; 25 teeth for each test group and five for each control group. After conducting conventional e...

Background/Aim. The ability to effectively and consistently penetrate into dentinal tubules is considered as a favorable factor of root canal sealers RCS). aim the study was assess penetration depth three RCS combined with four obturation techniques. Methods. Mesial canals 66 extracted human mandibular molars were endodontically prepared randomly allocated 12 experimental groups depending on se...

This in vitro study compared the ultrastructural quality of the apical seal achieved with Resilon/Epiphany and gutta-percha/AH Plus. Single-rooted extracted human teeth were prepared using a crown-down technique, debrided with NaOCl and EDTA, and obturated with either Resilon/Epiphany or gutta-percha/AH Plus. They were examined for gaps along canal walls using SEM, and for apical leakage using ...

The sealing of the root canal system is of fundamental importance for successful endodontic treatment. To obtain an adequate apical seal, many factors must be considered such as the presence of smear layer and the sealer applied. After canal preparation, this layer must be removed because it prevents close contact between the dentinal walls and the sealing material. The goal of this study was t...

background: endodontic sealers usually come in contact with adjacent tissues and their biocompatibility is key in a successful treatment. the purpose of this study was to assess the cytotoxicity of three resin-based sealers, namely ah plus, endorez, and epiphany in set and fresh states on an l929 cell line. materials and methods: in this in vitro experimental study, the materials were mixed acc...

The objective of this study was to compare the sealing ability of ActiV GP/glass ionomer (GI) sealer (Brasseler USA, Savannah, GA), Resilon/Epiphany (Pentron Clinical Technologies, Wallingford, CT), and gutta-percha (GP)/AH Plus (Dentsply Maillefer, Tulsa, OK). Seventy-three human single-rooted teeth were randomly divided into three test groups (20 canals each) and two control groups (5 positiv...

Aim of the study was to evaluate cytotoxicity of five root canal sealers at different intervals of time on HEK-293 (human embryonic kidney epithelial cells) and Vero cells (African green monkey kidney epithelial cells). Endomethasone N, EndoREZ, Acroseal, RoekoSeal and AH Plus were mixed according to manufacturer’s instructions. MTT assay was used to evaluate cytotoxicity of freshly mixed and s...


 Aim: The aim of this study is to evaluate the dislocation resistance three different resin-based root canal sealers from radicular dentin -An ‘in vitro’ study.
 Methodology: Sixty extracted human maxillary canines were sectioned transversally below cement-enamel junction obtain 2-mm-thick disks that randomly divided into groups (n = 20) for treatment with one root-canal (AH Plus [De...
