Bone tissue reaction, setting time, solubility, and pH of root repair materials

PURPOSE This study aims to compare the bone tissue reaction, setting time, solubility, and pH of NeoMTA Plus, Biodentine (BD), and MTA Angelus (MTA-A). METHODS Initial and final setting times (n = 7) and solubility up to 7 days (n = 11) were evaluated in accordance with ASTM C266–15 and ANSI/ADA Specification No. 57, respectively. pH (n = 10) was measured […]

Comparison of the sealing ability of apical plug materials in simulated open apices: An in vitro study

PURPOSE The aim of this study was to evaluate the microleakage of apical plugs made of four different materials in simulated immature teeth. METHODS Ninety extracted single-rooted teeth were selected and randomly divided into six groups according to the materials used: NeoMTA, EndoSequence Bioceramic Root Repair Material Fast Set Putty (BC RRMFS), Biodentine, Endo Repair, […]

Shear Bond Comparison between 4 Bioceramic Materials and Dual-cure Composite Resin

ABSTRACT INTRODUCTION: Bioceramic materials have shown biologic and physical properties favorable for regenerative treatment. A key to treatment success is an adequate restoration to prevent microleakage; however, research is limited regarding the bond strength between restorative and bioceramic materials used in regenerative procedures. This study compared the bond strength between 4 bioceramic materials and a […]

Physical and chemical properties of new-generation endodontic materials

ABSTRACT INTRODUCTION: Mineral trioxide aggregate (MTA), white and gray, has many uses in endodontic therapy but is limited by its difficult handling characteristics. This study compared the physical and chemical properties of white MTA (WMTA) with three experimental root-end filling materials: Capasio (Primus Consulting, Bradenton, FL), Ceramicrete-D (Tulsa Dental Specialties/Argonne National Laboratory, Argonne, IL), and […]

Biocompatibility and osteogenic potential of new generation endodontic materials established by using primary osteoblasts

ABSTRACT INTRODUCTION: Generex A and Generex B (calcium silicate based), Capasio (calcium-phospho-alumino silicate based) along with Ceramicrete-D (magnesium phosphate based) are being introduced as a new generation of endodontic materials with the potential to facilitate bone healing. The aim of this study was to evaluate the biocompatibility and osteogenic potential of these new materials by […]

Remineralization of artificial dentinal caries lesions by biomimetically modified mineral trioxide aggregate

ABSTRACT Fluoride-releasing restorative materials are available for remineralization of enamel and root caries. However, remineralization of dentin is more difficult than remineralization of enamel due to the paucity of apatite seed crystallites along the lesion surface for heterogeneous crystal growth. Extracellular matrix proteins play critical roles in controlling apatite nucleation/growth in collagenous tissues. This study […]

Effects of calcium silicate-based materials on the flexural properties of dentin

ABSTRACT INTRODUCTION: Prolonged exposure of root dentin to calcium hydroxide alters the fracture resistance of dentin. Calcium silicate-based materials (CSMs) used in endodontics release calcium hydroxide on setting. This study examined whether prolonged contact of dentin with CSMs adversely affects its mechanical properties. METHODS: Dentin beams prepared from extracted human molars (7 × 3 × […]

Effects of an experimental calcium aluminosilicate cement on the viability of murine odontoblast-like cells

ABSTRACT INTRODUCTION: Quick-setting calcium aluminosilicate cement with improved washout resistance is a potential substitute for calcium silicate cements in endodontics. This study examined the effect of an experimental calcium aluminosilicate cement (Quick-Set; Primus Consulting, Bradenton, FL) on the viability of odontoblast-like cells. METHODS: The biocompatibility of Quick-Set and white ProRoot MTA (WMTA; Dentsply Tulsa Dental […]

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 […]

Retreatability of 2 mineral trioxide aggregate-based root canal sealers: a conebeam computed tomography analysis

ABSTRACT 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 […]
