“…AB is composed of a reactive, ionic resin (bis-2-(methacryloyloxy)ethyl phosphate) (Bis-2), polycarboxylic acid, and reactive glass. It releases and recharges beneficial calcium, phosphate, and fluoride ions [ 24 ], which facilitate remineralization and reduce demineralization of dentinal tissues [ 25 ]. In addition to the incorporation of elements for bioactivity, AB materials also contain a rubberized polyurethane-methacrylate-resin that increases fracture toughness and mimics the toughness of dentin [ 26 ].…”

The aim of this study was to synthesize and characterize a novel methacrylate-functionalized calcium phosphate (MCP) to be used as a bioactive compound for innovative dental composites. The characterization was accomplished by attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). The incorporation of MCP as a bioactive filler in esthetic dental composite formulations and the ability of MCP containing dental composites to promote the precipitation of hydroxyapatite (HAp) on the surfaces of those dental composites was explored. The translucency parameter, depth of cure, degree of conversion, ion release profile, and other physical properties of the composites were studied with respect to the amount of MCP added to the composites. Composite with 3 wt.% MCP showed the highest flexural strength and translucency compared to the control composite and composites with 6 wt.% and 20 wt.% MCP. The progress of the surface precipitation of hydroxyapatite on the MCP containing dental composites was studied by systematically increasing the MCP content in the composite and the time of specimen storage in Dulbecco’s phosphate-buffered solution with calcium and magnesium. The results suggested that good bioactivity properties are exhibited by MCP containing composites. A direct correlation between the percentage of MCP in a composite formulation, the amount of time the specimen was stored in PBS, and the deposition of hydroxyapatite on the composite’s surface was observed.

The aim of this study was to synthesize and characterize a novel Methacrylate- functionalized Calcium Phosphate (MCP) used as a bioactive compound for innovative dental composites. The characterization was accomplished by Attenuated Total Reflectance Fourier-Transform Infrared Spectroscopy (ATR-FTIR), X-Ray Diffraction Analysis (XRDA), Scanning Electron Microscopy (SEM), and EnergyDispersive Spectroscopy (EDS). The incorporation of MCP as a bioactive filler in esthetic dental composite formulations and the ability of MCP containing dental composites to promote precipitation of hydroxyapatite (HAp) on the surfaces of those dental composites was explored. The translucency parameter, depth of cure, degree of conversion, ion release profile, and other physical properties of composites were studied with respect to the amount of MCP added to the composites. Composites containing 3 Wt.%, 6 Wt.%, and 20 Wt.% MCP were evaluated at 7, 14, and 21 days. The progress of surface precipitation of hydroxyapatite on MCP-containing dental composites was studied by systematically increasing the MCP content in the composite and the time of specimen storage in Dulbecco’s phosphate-buffered solution with calcium and magnesium. It was found that there was a direct correlation between the percentage of MCP in a composite formulation, the amount of time the specimen was stored in PBS, and the deposition of hydroxyapatite on the composite’s surface

Objectives: This study was designed to develop and assess the ions release property of an innovative experimental bioactive fiber-reinforce composite as a new material for an intra-canal post. Study Design: An in vitro studyMaterials and Methods: Surface treated unidirectional E-glass fiber were impregnated and implanted with a triple cure, self-adhesive ACTIVA BioACTIVE resin cement to fabricate an experimental bioactive glass fiber post using hand lay-up moulding technique and polytetrafluoroethylene (PTFE) moulds, The cylindrical and rectangular form specimens were prepared, for each specimen, ensure 3min for self-cure setting, then light-cured for the 40s. The specimens were individually immersed in a deionized (DI) water, and sodium chloride solution to assess the fluoride ion release, and calcium-phosphate ions release sequentially. Virgin ACTIVA BioACTIVE cement was used as a reference group for all investigations.Statistical analysis used: Statistical analysis was achieved by means of independent variable t-test, oneway ANOVA, and Bonferroni Pairwise comparisons utilizing IBM-SPSS software.Results: Experimental material recognized a significant reduction in F -, Ca +2, and PO 4 3release after reinforcement compared to virgin ACTIVA BioACTIVE. Conclusions:The ACTIVA BioACTIVE cement's reinforcement process reduced the ion release intensity of the material but not affected the releasing pattern.
