Background: It is difficult to identify a potential sealant with penetration depth until practically analyzed. A scanning electron microscopy (SEM) overview could better describe the internal picture of the materials sealed to the tooth surface on in vitro experimentation since it being a vital procedure for successful obturation. Hence, this study was undertaken to compare the penetration dept...

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 ...

AIM To evaluate the efficacy of the ProTaper Universal rotary retreatment system for gutta-percha (GP) removal from root canals. METHODOLOGY Root canals of 60 extracted human maxillary anterior teeth were prepared and filled with laterally condensed GP and AH Plus sealer. Teeth were divided into three groups: group A--GP removal completed with the ProTaper Universal rotary retreatment system ...

Coronal leakage is an important factor affecting the outcome of endodontic therapy. This study evaluated the microbial leakage (ML) and the apical inflammatory response (AIR) in dog's teeth after root canal filling with three endodontic sealers, post preparation and exposure to the oral environment, testing the hypothesis that there is a positive correlation between these two histological param...

INTRODUCTION The aim of the present study was to evaluate the physicochemical properties of a bioceramic root canal sealer, Endosequence BC Sealer. Radiopacity, pH, release of calcium ions (Ca(2+)), and flow were analyzed, and the results were compared with AH Plus cement. METHODS Radiopacity and flow were evaluated according to ISO 6876/2001 standards. For the radiopacity analysis, metallic ...

INTRODUCTION The aim of this study was to evaluate the effect of intra-canal calcium hydroxide (CH) remnants after ultrasonic irrigation and hand file removal on the push out bond strength of AH-26 and EndoSequence Bioceramic sealer (BC Sealer). METHODS AND MATERIALS A total of 102 single-rooted extracted human teeth were used in this study. After root canal preparation up to 35/0.04 Mtwo rot...

background and aims. with availability of hydrophilic sealers, drying of the canals before endodontic obturation is still a matter of debate. the aim of this study was to compare the apical micro-leakage of ah26, excite dsc, mta fillapex, and zoe sealers in dry and moist root canals. materials and methods. this experimental study was performed on 90 extracted maxillary central incisors. rotary ...

AIMS The aim of the study was to compare the antimicrobial property of newly introduced EndoSequence BC sealer with commonly used zinc oxide-eugenol-based sealer (Zical) and epoxy resin-based sealer (MM-Seal) against Candida albicans, Lactobacillus, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. MATERIALS AND METHODS The agar diffusion test was done to measure the antimi...

This study compared halothane and chloroform used with hand or ultrasonic instrumentation to remove gutta-percha and sealer from root canals. Apically extruded debris, residual debris, time for filling removal, and amount of solvent used were determined. The differences in extruded apical debris and radiographically visible residual debris were not significant (p greater than 0.05). Ultrasonic ...

AIM To evaluate whether application of a total-etch/separate adhesive layer can enhance the bond of a UDMA-based sealer to dentine. METHODOLOGY The root canals of 20 decoronated maxillary premolar teeth with two canals were prepared to size 35-45, 0.04 taper using rotary NiTi instruments. The canals of each tooth were treated with application of either a total-etch/separate adhesive or the ma...
