INTRODUCTION The purpose of this in vitro study was to evaluate three common gutta-percha solvents' effectiveness in dissolving three different types of root canal sealers. MATERIALS AND METHODS The solubility of three different root canal sealers (AH Plus, Apexit Plus and Endoflas FS) was assessed in xylene, refined orange oil, tetrachloroethylene and distilled water (control). One-hundred t...

INTRODUCTION Antibacterial activity is one of the desirable properties of an ideal sealer. This study aimed to compare the antimicrobial effect of three different sealers, i.e. resin (AH26), calcium hydroxide (Apexit) and zinc oxide eugenol (ZOE) based sealers. MATERIALS AND METHODS Direct contact test with agar diffusion was used in this in vitro study. The freshly mixed sealers were AH26, A...

INTRODUCTION The antibacterial effectiveness of 7 different endodontic sealers, AH Plus, Apexit Plus, iRoot SP, Tubli Seal, Sealapex, Epiphany SE, and EndoRez against Enterococcus faecalis was studied in vitro. METHODS A modified direct contact test was used. Bacteria in suspension were exposed to the materials for 2-60 minutes by using sealers that were freshly mixed or set for 1, 3, and 7 d...

INTRODUCTION The purpose of the current study was to estimate the biocompatibility of endodontic sealers with different bases on L929 mouse fibroblasts permanent cell line using Multiscan EX Spectrophotometer. MATERIALS AND METHODS Endodontics sealers used in this study were GuttaFlow (Roeko) silicone based sealer, AH plus (De Tray-DENTSPLY) epoxy resin based, Apexit (Vivadent) calcium hydrox...

OBJECTIVE To histologically evaluate the behavior of the subcutaneous tissue of rats after placement of polyethylene tubes filled with calcium hydroxide-based root canal sealers (Sealapex, Apexit e Sealer 26). STUDY DESIGN The study employed 60 rats, which were divided into eight groups, being four experimental groups with 10 rats each, and four control groups with five rats. Analysis was con...

PURPOSE The purpose of our study was to compare the in vitro release of hydroxyl ions from several calcium hydroxide preparations used in endodontic treatment. MATERIAL AND METHODS Equal quantities of the materials--nonsetting (pure calcium hydroxide, Biopulp, Calcicure), setting--canal sealers (Sealapex, Apexit) and points were placed in dialysis tubes which were then immersed in deionized w...

introduction: the purpose of this in vitro study was to investigate the influence of 5.25% sodium hypochlorite (naocl) and 0.12% chlorhexidine gluconate (chx) use separately and combined as endodontic irrigants on the apical sealing ability of two endodontic sealers. materials and methods: eighty-six extracted maxillary central incisor teeth were used. the teeth were decoronated at the cej, acc...

The purpose of the study was to evaluate the effect of MTAD in comparison with EDTA as a final rinse on the shear bond strength of Kerr, Apexit and AH plus. Dentine surfaces of 135 extracted human non-carious maxillary premolars were divided into three groups (n = 45). Groups I and II were conditioned with 1.3% NaOCl for 20 min, followed by a final rinse of 17% EDTA for 1 min and MTAD for 5 min...

INTRODUCTION The function of root canal fillings is to seal the root canal system. The important physical property necessary for sealers to achieve this is low solubility. However, any therapeutic effect of calcium hydroxide-based sealers is dependent on the calcium hydroxide being in ionized form, which implies that the material must be at least partly soluble. OBJECTIVE The objective of our...
