Pulpal responses after direct pulp capping with two calcium-silicate cements in a rat model.

Bioactivity of Bio-MA, a calcium chloride accerelator-containing calcium-silicate cement, as a pulp capping material was evaluated on mechanically exposed rat molar pulp. Sixty maxillary first molars from Wistar rats were mechanically exposed and assigned to two capping materials: Bio-MA or white mineral trioxide aggregate (WMTA), and three periods: 1, 7, or 30 days. Nine molars were exposed and covered with polytetrafluoroethylene tape, as positive controls.

Biocompatibility and Osteogenic/Calcification Potential of Casein Phosphopeptide-amorphous Calcium Phosphate Fluoride.

Introduction: Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and CPP-ACP with fluoride (CPP-ACFP) have been shown to provide bioavailable ions to promote mineralization. Hence, the aim of this study was to evaluate the materials' biocompatibility and osteogenic/calcification potential for endodontic applications.

Methods: Human and mouse osteoblast-like and fibroblast-like cell lines were incubated with 0.

The effect of working time on the displacement of Biodentine beneath prefabricated stainless steel crown: a laboratory study.

Objective: To investigate the displacement of Biodentine following cementation of stainless steel crowns (SSC) with glass-ionomer cement (GIC) on plastic deciduous teeth prepared for pulpotomy.

Methods: Twenty plastic teeth with prepared occlusal cavities were divided into four groups and had Biodentine placed as a mock pulpotomy agent. The pulp chamber was filled with freshly mixed Biodentine then a GIC-loaded SSC was seated on the tooth using a standardized seating force for periods of: 1 min (Group 1); 2 min (Group 2), 3 min (Group 3) and 6 min (Group 4) after mixing.

Push-out bond strength of CPP-ACP-modified calcium silicate-based cements.

This study evaluated the push-out bond strength of 0%, 0.5%, 1.0%, 2.

Fracture force of cantilevered zirconia frameworks: an in vitro study.

Statement Of Problem: Little evidence is available showing the effect of connector dimension and cantilever length on the ultimate fracture force of computer-aided design/computer-aided manufacturing (CAD/CAM) zirconia implant frameworks.

Purpose: The purpose of the study was to determine the impact of variations in the cross-sectional dimension of connector sites and variations in the effective cantilever length (load point) on zirconia implant frameworks. This would allow verification of the fracture force with 2 proposed mathematical models.

Effects of casein phosphopeptide-amorphous calcium phosphate remineralizing paste and 8% arginine desensitizing paste on dentin permeability.

Aim: To compare the effects of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste and 8% arginine paste on dentin permeability.

Methods: Sixteen human third molars were sectioned to remove the roots and expose occlusal dentin surfaces. The pulpal side was flattened to obtain 1 mm remaining dentin thickness.

Effect of CPP-ACP addition on physical properties of zinc oxide non-eugenol temporary cements.

Objectives: Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is a milk derivative which holds nanoclusters of calcium and phosphate ions. The presence of CPP-ACP has been found to reduce demineralization and enhance remineralization in subsurface enamel and in dentin. Incorporation of CPP-ACP into luting cements has not been investigated.
