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 […]

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 calcium silicate-based materials on collagen matrix integrity of mineralized dentin

ABSTRACT INTRODUCTION: Calcium silicate-based materials (CSMs) are used in various endodontic procedures. The present study examined whether prolonged contact of mineralized dentin with recently commercialized versions of these materials adversely affects dentin collagen matrix integrity. METHODS: Dentin slabs prepared from extracted human third molars (7 × 3 × 0.3 mm) were divided into 3 groups […]

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 […]

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 […]

In vitro osteogenic/dentinogenic potential of an experimental calcium aluminosilicate cement

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 […]

In vitro biocompatibility and oxidative stress profiles of different hydraulic calcium silicate cements

ABSTRACT INTRODUCTION: MTA Plus is a new calcium silicate cement with unknown cytotoxicity characteristics. The objectives of this study were to examine the effect of MTA Plus on the viability, apoptosis/necrosis profile, and oxidative stress levels of rat odontoblastlike cells. METHODS: MDPC-23 cells were exposed to gray and white MTA Plus (GMTAP, WMTAP), gray and […]

Evaluation of compressive strength of hydraulic silicate-based root-end filling materials

ABSTRACT INTRODUCTION: Hydraulic silicate cements such as mineral trioxide aggregate (MTA) have many clinical advantages. Newer hydraulic silicate materials have been developed that improve on the limitations of mineral trioxide aggregate such as the long setting time and difficult handling characteristics. The purpose of this study was to examine the effect of saline and fetal […]
