The aim of this study was to evaluate the effect of an epoxy resin-based (AH-Plus), a zinc oxide eugenol containing (Pulp-Canal-Sealer) and two calcium silicate containing (MTA-Fillapex and BioRoot-RCS) sealers on primary human osteoblasts (hOB) in freshly mixed and set state. All sealers were mixed strictly according to the manufacturers´ instructions and identically samples were produced. In ...

Microbes are considered as the primary etiologic agents in endodontic diseases. The ways of reducing these agents are: root canal debridement, antimicrobial irrigants and antibacterial filling materials. But the complexity of the pulp canal system presents a problem for chemo mechanical preparation. One of the factors determining the success of endodontic treatment is the sealing material with ...

This study evaluated the cytotoxicity, antimicrobial and physicochemical properties of root canal sealers incorporated with phytotherapic Uncaria tomentosa (UT). Unmodified AH Plus (Dentsply, DeTrey, Germany) MTA Fillapex (Angelus, Londrina, Brazil) were used as controls. UT was into Fillapex, at concentrations 2% 5% total weight these (w/w). Flowability, setting time, solubility following ISO ...

BACKGROUND/AIM Endodontic sealers (ES) for obturation are usually prepared with a slight variation of their components both on purpose or unintentionally. Considering that fact, as well as a frequent use of compaction techniques with the applied force to gutta-percha and ES of 1-3 kg, the aim of this study was to investigate the flow of two zinc-oxide eugenol ES in regard to the applied force a...

Introduction Coal tar is derived from crude coke oven tar that is a by-product of the combustion of coal in steel manufacturing. The crude coke oven tar is then refined, through...

Aim: of this study was to assess and compare, the radiopacity nanoparticle-based (NPB) root canal sealers with Epoxy Resin Based(ERB) sealer using an aluminium step wedge in accordance ISO 6876/2012 standards. Materials methods: The specimens, which were made each material, had a 10mm diameter 1mm thickness. creation metallic matrices, used fabrication impressions, done light-bodied silicone-ba...

Abstract New methodologies using micro-CT to evaluate solubility besides dimensional and morphological changes of endodontic materials are proposed. However, there is no standardization in the methods. The aim this study was assess effect different dimensions test samples on volumetric change evaluation materials. AH Plus, FillCanal Sealapex root canal sealers, Biodentine, IRM MTA root-end fill...

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 MATERI...
