Mineral trioxide aggregate with anti-washout gel – properties and microstructure

ABSTRACT INTRODUCTION: One of the problems encountered clinically when using mineral trioxide aggregate (MTA) as a root-end filling material is washout immediately after placement. A novel MTA is supplied with an anti-washout gel that replaces the mixing water. The aim of this research was to characterize and assess the properties of a novel MTA mixed […]

The setting characteristics of MTA Plus in different environmental conditions

ABSTRACT INTRODUCTION: Characterization and assessment of the hydration reaction of mineral trioxide aggregate (MTA) Plus exposed to different environmental conditions. METHODS: The specific surface area, surface morphology and characterization of un-hydrated MTA Plus (Avalon Biomed Inc. Bradenton, FL, USA) were investigated. The specific surface area was compared with that of ProRoot MTA (Dentsply International, Tulsa […]

Push-out bond strength of MTA with antiwashout gel or resins

ABSTRACT INTRODUCTION: This study’s aim was to make an assessment of the push-out bond strength of four MTA-based formulations for use as root-end filling materials. METHODS: MTA Plus mixed with (i) water (‘MTA-W’); (ii) a proprietary water-based antiwashout gel (‘MTA-AW’); (iii) Superbond C&B chemically curing resin (‘MTA-Chem’); and (iv) Heliobond light-curing resin (‘MTA-Light’) was tested.

Biocompatibility and mineralized nodule formation of Neo MTA Plus and an experimental tricalcium silicate cement containing tantalum oxide

ABSTRACT INTRODUCTION: The aim of this study is to evaluate the biocompatibility and mineralized nodule formation of an experimental tricalcium silicate cement with tantalum oxide (TSC/T2aO5) as radiopacifier, Neo MTA Plus (Avalon Biomed Inc., Bradenton, FL, USA) and MTA (Angelus, Londrina, PR, Brazil) on human osteoblast-like cells (Saos-2). METHODS: Biocompatibility was evaluated by 3-(4,5-dimethyl-thiazoyl)-2,5-diphenyl-tetrazolium bromide […]

Staining Potential of Neo MTA Plus, MTA Plus, and Biodentine Used for Pulpotomy Procedures

ABSTRACT INTRODUCTION: Mineral trioxide aggregate (MTA) used for pulpotomy procedures in immature permanent teeth can reduce treatment to 1 session as opposed to classic calcium hydroxide therapy, which necessitates multiple appointments. The main disadvantage of MTA use is crown discoloration after treatment. The aim of this study was to characterize 3 materials that are used […]

Mineral trioxide aggregate with anti-washout gel – Properties and microstructure

Abstract Introduction:Calcium aluminosilicate cements are fast-setting, acid-resistant, bioactive cements that may be used as root-repair materials. This study examined the osteogenic/dentinogenic potential of an experimental calcium aluminosilicate cement (Quick-Set) by using a murine odontoblast-like cell model. Methods: Quick-Set and white ProRoot MTA (WMTA) were mixed with the proprietary gel or deionized water, allowed to set completely […]

A quantitative method for determining the anti-washout characteristics of cement-based dental materials including mineral trioxide aggregate

Abstract: Aim: To introduce and assess a novel method for measuring washout resistance of cement-based dental materials, including mineral trioxide aggregate (MTA), to qualitatively verify the results with a clinical simulation and to evaluate the washout resistance of a new root-end filling material. Methodology: A method for assessment of washout resistance of root-end filling materials was developed by adapting the CRD-C 661-06 […]
