OBJECTIVE The aim of this study was to compare the cytotoxic effects of endodontic cements on human tooth germ stem cells (hTGSCs). MTA Fillapex, a mineral trioxide aggregate (MTA)-based, salicylate resin containing root canal sealer, was compared with iRoot SP, a bioceramic sealer, and AH Plus Jet, an epoxy resin-based root canal sealer. MATERIAL AND METHODS To evaluate cytotoxicity, all mat...

INTRODUCTION The aim of this in vitro study was to evaluate the effect of MTA-based sealer (MTA Fillapex), eugenol-based sealer (Dorifill) and an epoxy resin sealer (AH Plus) on the bond strength of fiber posts cemented with a self-etch adhesive. MATERIALS AND METHODS The root canals of 72 maxillary incisors were prepared using the step-back technique after removing/cutting off the crowns. Th...

OBJECTIVE The aim was to evaluate the apical sealing ability of tricalcium silicate-based (MTA Fillapex®) and resin-based (AH Plus®) sealers at 24 h, 7 days and 4 weeks. MATERIALS AND METHODS Thirty-four extracted human upper anterior teeth were used. All the teeth were sectioned to leave the root 15 mm long, and then all the roots were instrumented using a set of ProTaper® rotary instruments...

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...

INTRODUCTION The cytotoxicity of 2 novel calcium silicate-containing endodontic sealers to human gingival fibroblasts was studied. METHODS EndoSequence BC (Brasseler, Savannah, GA), MTA Fillapex (Angelus Indústria de Produtos Odontológicos S/A, Londrina, PR, Brazil) and a control sealer (AH Plus; Dentsply DeTrey GmbH, Konstanz, Germany) were evaluated. Human gingival fibroblasts were incubate...

BACKGROUND The aim of this in vitrostudy was to examine and compare the effect of photodynamic therapy and solution containing nano particles Ag/ZnO on adhesion of endodontic sealers to dentinal walls of human root canal. MATERIAL AND METHODS Ninty single-rooted human teeth were selected and their clinical crown was cut from the cemento-enamel junction zone. Canals were prepared by RaCe rotar...

UNLABELLED Crown discoloration can be induced by root canal sealer remnants following root canal treatment. OBJECTIVE The aim of this study was to evaluate chromatic alterations in human tooth crowns induced by a Mineral Trioxide Aggregate-based sealer (MTA Fillapex®) and a commonly used ZnOE-based sealer (Roth-811). The tested null hypothesis was that the application of the materials did not...

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,...

Objectives: This study aimed to assess tooth discoloration at 6 months following the use of 5% fluoride varnish (Duraflur), AH 26, zinc oxide eugenol (ZOE)-based sealer and mineral trioxide aggregate (MTA)-based sealer in extracted premolars. Materials and Methods: In this in vitro, experimental study, 75 freshly-extracted human premolars with completely formed roots underwent root canal treat...

BACKGROUND Sealing ability is one of the most important features of endodontic sealers. The purpose of this in vitro study was to compare the sealing ability of a resin-based sealer with a mineral trioxide aggregate-based sealer. MATERIALS AND METHODS A total of 60 single-rooted extracted human teeth were randomly divided into two experimental groups (n = 25) and two control groups (n = 5). A...
