AIM The aim of this in vitro study was to evaluate the apical seal obtained with four root canal sealers AH 26, Sealapex, Endoflas FS and AH Plus, with lateral condensation. MATERIALS AND METHODS Sixty root canals were prepared using the step-back technique. The specimens were divided into four experimental groups of 12 teeth and two control groups of 12 teeth. The experimental groups were ob...

introduction: the purpose of this study was to compare the subcutaneous tissue responses of freshly mixed or set endodontic root canal sealers ( i.e. roekoseal, ah26, ah plus) in wistar albino rats. materials and methods: seventy-two male albino rats weighing 200-250g were used. the animals were randomly divided into six groups of 12 rats each. root canal sealers were implanted in subcutaneous ...

introduction: vertical root fracture inevitably leads to tooth extraction. thus, root filling with obturating materials and sealers that can reinforce the tooth would be an ideal way to reduce fracture in root treated teeth. this study aimed to assess the fracture resistance of roots following the application of different sealers including epiphany, iroot sealer and ah-plus. methods and materia...

The aim of the present study was to compare the porosity characteristics of AH Plus Jet(tm) syringe-mix and the conventional hand-mixed AH Plus root canal sealers by three-dimensional quantitative high-resolution micro-computed tomography (micro-CT). Seven test specimens were prepared from each tested sealer by a single operator following the manufacturer's instructions and poured into pre-lubr...

UNLABELLED   INTRODUCTION The aim of this study was to examine and compare the apical sealing ability of AH26, AH Plus and AH Plus Jet using the fluid filtration model. MATERIALS AND METHODS In this experimental study, 70 single-rooted teeth were dissected from the cement-enamel junction. Canals were prepared with ProTaper rotary system and hand K-files and irrigated with 5.25% NaOCl and 17...

AIM The purpose of this study was to determine whether AH 26 and AH Plus have in vitro oestrogenic effects. METHODOLOGY MCF-7 breast cancer cells were trypsinized and plated in 24-well plates at initial concentrations of 10,000 cells per well in 5% FBS in DME. Cells were allowed to attach for 24 h; then the seeding medium was replaced with 10% CDHuS-supplemented phenol red-free DME. Different...

the aim of this study was to evaluate and compare the cytotoxicity induced by two resin-based sealers, 2seal and ah plus, in two osteoblast-like cell lines, mg-63 and saos-2. using sterile discs of both sealers in complete media, 24- and 72-h extracts were prepared. the extracts were exchanged with saos-2 or mg-63 cell culture media at 75% confluence, and after 24 h incubation, cell viability t...

The idea of using ozone to disinfect root canals is of recent origin. The wide acceptance of epoxy resin-based sealers lead us to investigate whether ozone can influence the adhesion to the dentin. In this study, we tested the shear bond strength of AH Plus and EZ Fill. Forty freshly extracted bovine teeth were randomly divided into 5 groups. 16 of these samples were treated with ozone for 60 s...

introduction: this study aimed to evaluate the dentin-sealer interface in three different sealers using scanning electron microscopy (sem). methods and materials: thirty extracted human single-rooted teeth were prepared using protaper rotary files and were randomly divided into three groups ( n =10) including bc sealer, ah-plus and dorifill. the root canals were filled with cold lateral condens...

INTRODUCTION Assessment of cellular cytotoxicity is a regular method for evaluating the biocompatibility of novel materials. In a recent study, 5% fluoride varnish (Duraflur) has shown reasonable sealing ability and coverage of root canal walls when used as a sealer. The aim of the present study was to compare the cytotoxicity of Duraflur varnish with two popular commonly used root canal sealer...
