Development of a simplified etch-and-rinse adhesive containing niobiophosphate bioactive glass
Source abstract
Abstract
Abstract Purpose The aim of this study was to evaluate radiopacity, degree of conversion (DC), Knoop hardness (KHN), ultimate tensile strength (UTS) and microtensile bond strength (µTBS) to dentin of an experimental adhesive containing micro-filler of niobium–phosphate bioactive glass (NPG). Materials and methods The NPG glass was produced by fusion of NbO5, Na2CO3, CaO, (NH4)2HPO4 at 1400 °C. After cooling, the glass was ground to a mean particle size Results The presence of glass particles made the adhesive system radiopaque. Addition of bioactive NPG glass particles to the adhesive system prevented decreases in bond strength; reduced the UTS and increased DC and KHN. All groups showed predominance of adhesive failure mode. Conclusion Addition of 40% NPG glass may be an alternative to obtain an adhesive system with adequate mechanical and bond strength to dentin properties.
