OBJECTIVES A variety of root canal sealers were recently launched to the market. This study evaluated physicochemical properties, biocompatibility, and sealing ability of a newly launched resin-based sealer (Dia-Proseal, Diadent) compared to the existing root canal sealers (AHplus, Dentsply DeTrey and ADseal, Metabiomed). MATERIALS AND METHODS The physicochemical properties of the tested seal...

INTRODUCTION The aim of this in vitro study was to evaluate the effect of canal dryness on the push-out bond strength of two resin sealers (AH-Plus and Adseal) and a bioceramic sealer (Endosequence BC sealer) after canal irrigation with sodium hypochlorite (NaOCl) and chlorhexidine (CHX). METHODS AND MATERIALS A total of 18 extracted human premolars were used. Canals were prepared and were di...

Background and Aim: Tooth discoloration induced by endodontic sealers is an un-desired outcome of endodontic treatment that affects the esthetic appearance of the teeth, which is important especially in the anterior region. The aim of the present study was to compare the coronal discoloration caused by two frequently used resin-based sealers namely EasySeal and AdSeal. Materials and Methods: F...

OBJECTIVES This study evaluated the efficacy of Endosolv-R and Xylene in softening epoxy resin based sealer after 1 to 2 min exposure. MATERIALS AND METHODS Sixty Teflon molds (6 mm × 1.5 mm in inner diameter and depth) were equally divided into 3 groups of 20 each. AH 26 (Dentsply/De Trey), AH Plus (Dentsply/De Trey), Adseal (Meta-Biomed) were manipulated and placed in the molds allotted to ...

Introduction: Growth and proliferation of the remaining microorganisms within the root canals may destroy the surrounding tissue of the root and leads to periapical lesion. Consequently, the complete elimination of microorganisms from the root canal is a n important goal of endodontic therapy. Endodontic sealers do not provide complete seal in root canal system, and micro spaces have always rem...

Since the setting characterization of a root canal sealer has an impact on its biological behavior final obturation, this study evaluated mineral trioxide aggregate MTA-Fillapex versus MTA-Bioseal compared with epoxy resin (Adseal) sealers. Freshly mixed was inserted into mold (n = 10). The initial and times were using Vicat needle then statistically analyzed by one-way ANOVA at p < 0.05. ra...

INTRODUCTION Microleakage can result in failure of endodontic treatment. An important characteristic of endodontic sealer is sealing ability. The aim of this experimental study was to compare the apical leakage of teeth obturated with gutta-percha and three different sealers (resin- and zinc oxide eugenol-based) with/without smear layer (SL). MATERIALS AND METHODS In this study, 100 single-ro...

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...

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...
