Newly available materials for retrograde obturation should have their sealing properties evaluated. The goal of this study was to evaluate the sealing ability of Endo CPM sealer, an MTA-based endodontic cement. Single-rooted extracted human teeth were endodontically treated. After apical sectioning, retrograde cavities were prepared. Teeth were divided into five experimental groups (n=12), in w...

BACKGROUND Sealing ability is one of the most important features of endodontic sealers. The purpose of this in vitro study was to compare the sealing ability of a resin-based sealer with a mineral trioxide aggregate-based sealer. MATERIALS AND METHODS A total of 60 single-rooted extracted human teeth were randomly divided into two experimental groups (n = 25) and two control groups (n = 5). A...

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. ...

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...

INTRODUCTION Three-dimensional obturation of the root canal system is the final objective of root canal therapy. Greater penetration of sealer in root dentine lesser will be the voids at the dentine-sealer interface. Hence, analysis of the dentin/sealer interface allows the determination of a filling technique which could obturate the root canals with least gaps and voids. Therefore, the aim of...

Abstract Although mineral trioxide aggregates (MTA) have been adopted as an endodontic sealer because of excellent sealing effect and bioactive property modified with improvement its characteristics, the developed MTA sealers not yet satisfied all ideal requirements sealers. The aim this study was to assess characteristics elastin-like polypeptide (ELP)-incorporated for use compare them those c...

Aim of the study is to compare quality apical seal offered by a zinc-eugenol and tricalcium-silicate-based sealer, both used with single-cone or continuous wave condensation technique. Forty central incisors were divided into four groups (n = 10), according two sealers obturation techniques under investigation, their outer surface was isolated nail varnish. After endodontic treatment, samples i...

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...

PURPOSE To investigate the sealing properties of root fillings with resin-coated gutta-percha cones and a methacrylate-based resin endodontic sealer with and without an accelerator component in root canals subjected to immediate or delayed post space preparation. METHODS Forty-eight extracted human teeth with single straight root canals were treated endodontically. Specimens were then assigne...

Endodontic sealers that possess both optimum flow ability and antimicrobial properties may theoretically assist in the elimination of microorganisms located in confined areas of the root canal system. The antimicrobial effects and the flow rate of the following sealers were investigated and compared: Kerr Pulp Canal Sealer EWT, Grossman's Sealer, ThermaSeal, Sealer 26, AH Plus, and Sealer Plus....
