Abstract
Recently, remineralization of artificial dentin lesion from exposure to a novel resin-based Ca-PO4 pulp capping or lining cement (RCPC) has been reported. This cement has moderate adhesion to dentin, presumably due to the presence of the acidic resin pyromellitic glycerol dimethacrylate (PMGDM). Dentin bonding agents placed between cement and dentin surface to enhance the adhesion severely compromised the remineralization. To aid in remineralizing the mineral-deprived surface after acid-etching used in bonding procedures or to improve the remineralization from RCPC via a bonding agent barrier, use of calcium phosphate-filled single solution bonding agents have been proposed.It was the purpose of this study to evaluate the effects of the resin composition (PMGDM vs. HEMA) and type and amount of the calcium phosphate filler on biaxial flexural strength and ion release from bonding agent specimens prepared without solvent. The composition with the highest calcium and phosphate ion release was further investigated in dentin bond tests varying the PMGDM to HEMA proportions, and the filler and solvent concentrations. With respect to the calcium and phosphate ion release and bond strength properties, the formulation with DCPA and the resin with a higher proportion of the acidic monomer PMGDM is advantageous.Proceedings Title
