INTRODUCTION: The aim was to compare the solubility, radiopacity, and setting times of a tricalcium silicate-containing (BioRoot RCS; Septodont, St Maur-des-Fossés, France) and a mineral trioxide aggregate-containing sealer (MTA Fillapex; Angelus, Londrina, Brazil) with an epoxy resin-based sealer (AH Plus; Dentsply DeTrey, Konstanz, Germany). METHODS: Solubility in distilled water, radiopacity, and setting time were evaluated in accordance with ISO-6876:2012. The solubility was also measured after soaking the materials in phosphate-buffered saline buffer (PBS)...

BACKGROUND: The aim of this study was to evaluate the bond strength of AH plus, Acroseal, and Adseal to the root canal dentin. METHODS: A total of 36 single-rooted, mandibular premolar teeth were used. Root canal shaping procedures were performed with ProTaper rotary instruments (Dentsply Maillefer) up to size F4. The prepared samples were then randomly assembled into 3 groups (n = 12). For each group, an ultrasonic tip (size 15, 0.02 taper) which was also coated with an epoxy resin based sealer and placed 2 mm shorter than the working length...

AIM: To compare the amount of apically extruded debris and of remaining filling material during the removal of root canal filling material using three rotary NiTi retreatment instruments or Hedström files. METHODOLOGY: Ninety-six severely curved human molars of both jaws were selected. The root canals were prepared to size X2 (tip size 25, .06 taper) using the ProTaper Next system (Dentsply Sirona, Ballaigues, Switzerland), filled with gutta-percha and AH Plus sealer (Dentsply De Trey, Konstanz, Germany) and were randomly divided into 4 experimental groups (n= 24 each) with two subgroups of maxillary and mandibular teeth each...

BACKGROUND: Complete removal of old filling material during root canal retreatment is fundamental for predictable cleaning and shaping of canal anatomy. Most of the retreatment methods tested in earlier studies have shown inability to achieve complete removal of root canal filling. Therefore the aim of this investigation was to assess the efficacy of three different rotary nickel titanium retreatment systems and Hedstrom files in removing filling material from root canals. MATERIAL AND METHODS: Sixty extracted mandibular premolars were decoronated to leave 15 mm root...

This study aimed to investigate the effect of epigallocatechin-3-gallate (EGCG) from green tea extract on the push out bond strength of an epoxy resin sealer to root dentin. Seventy single root canal premolars were decoronated and instrumented. The roots were randomly irrigated with different final irrigation protocols (n=16): 17%EDTA (EDTA), 17%EDTA followed by 2.5%NaOCl (EDTA+NaOCl), 17%EDTA followed by 1 mg/mL EGCG (EDTA+EGCG) and 1 mg/mL EGCG (EGCG). Other six root canals were received only 2.5%NaOCl as a control group...

This study tested the null hypothesis that the opacity of RealSeal SE (RSSE) sealer makes light-curing inefficient, while the degree of conversion (DC) is similar regardless of curing method. Fourteen uniradicular teeth were sectioned at 15 mm from the apex. Root canals were instrumented using the Reciproc file system, bulk-filled with RSSE, and divided randomly into two groups (dual-cure or self-cure). DC was determined by micro-Raman spectroscopy at 24 h, 48 h, and 1 week after filling, at 6, 9, and 12 mm from the coronal end...

OBJECTIVES: This study assessed the outcome measures of single-visit root canal retreatments and frequency of periapical complications considering preoperative, intraoperative and postoperative factors. MATERIALS AND METHODS: Between November 2011 and December 2012, in 173 patients, a total of 234 endodontically treated teeth were retreated in a single appointment by one experienced endodontist. Five teeth were extracted and 119 teeth were lost to follow-up yielding to 110 teeth (47 %) to be examined by two calibrated examiners for the outcome of healing (periapical index score-PAI ≤2; no signs or symptoms) or non-healing (presence of apical periodontitis-PAI >2; signs or symptoms)...

In the field of endodontology, antibacterial activity of irrigants has been investigated many times. The influence of these solutions on the bonding of root canal sealers, however, has hardly been studied. The objective of this doctoral research was to determine the interactions between root canal sealers and root dentin, and to determine the influence of irrigants on these interactions. The various studies revealed that irrigants have an influence on the bonding of sealers based on epoxy resin, calcium hydroxide, silicones and calcium silicate...

INTRODUCTION: The present study aimed to rank the bond strength to root dentin of a new injectable pozzolan-based root canal sealer, EndoSeal MTA, as compared with MTA Fillapex and AH Plus. METHODS: Eighteen dentinal slices (1 ± 0.1 mm) were obtained from the middle third of 6 maxillary incisors previously selected. Three canal-like holes with 0.8 mm diameter were drilled perpendicularly on the axial surface of each slice. Then, a standardized irrigation was applied for all holes that were subsequently filled with 1 of 3 test root canal sealers...

INTRODUCTION: Root canal obturation is the most important step in the root canal treatment that aims to obtain a complete hermetic seal and to prevent the re-growth of microorganisms in the root canal system. To accomplish this, many endodontic obturation materials and sealers are being used. AIM: To evaluate and compare the apical microleakage of a resin based sealer; Adseal with Mineral Trioxide Aggregate (MTA) based sealers; Pro root MTA and MTA Fillapex. MATERIALS AND METHODS: Total 75 extracted human single rooted teeth were taken and decoronated at cemento-enamel junction...

Aim: Comparative analysis of the coronal microleakage of a self-etching priming dentin adhesive with the use of antioxidant (Sodium Ascorbate (SA) and herbal quercetin) after Sodium hypochloride (NaOCl) and hydrogen-peroxide (H 2O2) irrigation. Materials and Methods: Seventy single root canals were enlarged and seven different treatment protocols were applied throughout the root canal treatment. The groups 1, 2 and 3 were irrigated with NaOCl. Group 1 was used as the negative control with only NaOCl irrigation whereas in group 2, Sodium ascorbate was applied as an additional irrigation agent following NaOCl...
