Aim: The aims of this study were to analyze the chemical constitution and the presence of heavy metals in MTA Fillapex and AH Plus sealers. Methods: The main components of the sealers were analyzed by using a Scanning Electron Microscopy equipped with Energy Dispersive X-ray analysis (SEM/EDX), and the concentration of 11 heavy metals (arsenic, bismuth, cadmium, calcium, copper, chromium, iron,...

The aim of this study was to compare the in vitro cytotoxicity of white mineral trioxide aggregate (MTA), MTA Fillapex® and Portland cement (PC) on human cultured periodontal ligament fibroblasts. Periodontal ligament fibroblast culture was established and the cells were used for cytotoxic tests after the fourth passage. Cell density was set at 1.25 X10 4 cells/well in 96-well plates. Endodonti...

Human dental pulp stem cells (HDPSCs) are of special relevance in future regenerative dental therapies. Characterizing cytotoxicity and genotoxicity produced by endodontic materials is required to evaluate the potential for regeneration of injured tissues in future strategies combining regenerative and root canal therapies. This study explores the cytotoxicity and genotoxicity mediated by oxida...

Introduction: This study aimed to compare Guttaflow bioseal, MTA-Fillapex, and AH plus with regards their adaptability on dentin surface. Methods: Thirty (n=30) single rooted human teeth were instrumented divided into three groups according the type of sealer used (each n=10). All root canals obturated lateral compaction technique. Roots cut longitudinally evaluated for using scanning electron ...

introduction: mineral trioxide aggregate (mta) as an alternative material to gutta-percha for obturation of root canal in special cases has several drawbacks. the purpose of this study was to compare the apical sealing ability of a new mta-based sealer versus mta. materials and methods: a total of 36 canals of extracted maxillary central incisors were instrumented and randomly divided into 3 ex...

  Aim: The aim of this study is to evaluate the retreatability bioceramic sealers (Endosequence BC, Totalfill MTA-Fillapex) used with single cone obturation technique. Materials and methods: Root canal forty rooted human mandibular premolar teeth were prepared ProTaper Next rotary system up X3 obturated technique (n=10) using endosequence BC (A), Totallfill (B), MTA-Fillapex (C) Zinc oxide...

statement of problem: adhesion to root canal dentin is one of the necessary characteristics of endodontic sealers. mta fillapex (angelus, londria, pr, brazil) is one of the recently introduced mta-based sealer. only a limited number of studies have evaluated the bonding of this sealer to the dentin, with conflicting results. objectives: the purpose of this study was to evaluate the bond strengt...

INTRODUCTION The retreatability of recent calcium silicate or mineral trioxide aggregate (MTA) sealers has not yet been assessed. The aim of this study was to evaluate the removal of 2 MTA-based sealers (MTA Fillapex [Angelus Soluções Odontológicas, Londrina, PR, Brazil] and MTA Plus [Prevest-Denpro, Jammu City, India]) using a rotary retreatment system, considering an epoxy resin sealer (AH Pl...

INTRODUCTION The aim of this study was to evaluate the retreatability of root canals obturated with gutta-percha (GP) and three different endodontic sealers [iRoot SP (bioceramic sealer), MTA Fillapex (MTA-based sealer) and AH-26 (epoxy resin-based sealer)] using the ProTaper Universal Retreatment (PTR) system. METHODS AND MATERIALS Forty extracted single-rooted human teeth were prepared with...

The physical properties of sealers were evaluated for flow, setting time, radiopacity, dimensional stability, PH change, and solubility. Thus, the aim this study was to compare a new calcium silicate-based sealer (Ceraseal) with 2 well established root canal (MTA Fillapex & AH Plus) based on their alkalinity Three already Fillapex, Ceraseal assessed solubility among 40 samples. For flow eva...
