introduction: a desirable quality of any endodontic sealer is its ability to be tooth color friendly. therefore the aim of the present study was to evaluate the tooth discoloration potential of a nano zinc oxide-eugenol (nzoe) sealer. methods and materials: in order to evaluate tooth discoloration, the pulp chamber of 60 human maxillary central and lateral incisors were filled with one of the s...

The most-popular root canal filling materials for primary teeth are zinc oxide eugenol (ZOE), iodoform paste, and calcium hydroxide. Root canal filling materials need to be biocompatible with the periapical tissue. There are few papers which indicate the mechanism of cellular change of root canal filling materials. The purpose of the present study was to evaluate the cellular changes of a ZOE w...

Introduction: Airtight sealing of the root canal is foremost desirable result any treatment, but getting perfect filling always problematic, which could be due to multiple reasons. One such majorly reason impacting obturation sealer utilized. Objective: The present study was done for evaluating microleakage in zinc oxide eugenol cement (ZOE) and epoxy resin-based (AH Plus) sealers using linear ...

introduction: the aim of this in vitro study was to evaluate the dissolving efficacy of eucalyptol and orange oil solvents associated with passive ultrasonic activation (pua) in zinc oxide-eugenol (zoe) based and epoxy resin-based root canal sealers. methods and materials: seventy samples of each sealer were prepared and then randomized according to the solvent and the time of the ultrasonic ac...

  Aim: The aim of this study is to evaluate the retreatability bioceramic sealers (Endosequence BC, Totalfill MTA-Fillapex) used with single cone obturation technique. Materials and methods: Root canal forty rooted human mandibular premolar teeth were prepared ProTaper Next rotary system up X3 obturated technique (n=10) using endosequence BC (A), Totallfill (B), MTA-Fillapex (C) Zinc oxide...

Introduction: Optimal radiopacity is one of the properties required for a root canal sealer that helps the distinction between the sealer and surrounding anatomic structures and evaluation of the quality of root filling. So, the purpose of this study was to evaluate the radiopacity of six root canal sealers at different focal distances. Materials and Methods: In this in vitro study, six endodo...

Using the agar diffusion method, this study evaluated the in vitro antimicrobial activity of the commercial endodontic sealers Acroseal and Epiphany, a castor-oil based experimental sealer, Polifil, and a primer agent (Epiphany self-etching primer), against Enterococcus faecalis. Zinc oxide and eugenol cement (ZOE) served as control. Five wells per dish were made at equidistant points and immed...

Background and Purpose Root canal therapy is the primary method for the treatment of an infected pulp in modern dentistry. The main aim of endodontic treatment is the elimination of bacteria and their products from infected root canals. In this study, we attempted to investigate the antimicrobial activity of three root canal sealers against oral pathogens. Materials and Methods The antimicrob...

AIM To evaluate the outcome of root canal treatment in primary teeth using three root canal filling materials - RC Fill, Vitapex and Pulpdent root canal sealer. METHODOLOGY The study was a single-centre, double-blind, randomized controlled trial carried out on 129 primary mandibular molars with necrotic pulps or irreversible pulpitis in 4- to 9-year-old children. Participants were selected ba...

INTRODUCTION The aim of this in vitro study was to evaluate the cytotoxicity of a new nano zinc-oxide eugenol (NZOE) sealer on human gingival fibroblasts (HGFs) compared with Pulpdent (micro-sized ZOE sealer) and AH-26 (resin-based sealer). METHODS AND MATERIALS The Pulpdent, AH-26, and NZOE sealers were prepared and exposed to cell culture media immediately after setting, and 24 h and one we...
