New Findings in Dentistry Described from Institute for Chemistry (Functionalizing a dentin bonding resin to become bioactive)

September 10, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Research findings on Dentistry are discussed in a new report. According to news reporting out of Zurich, Switzerland, by NewsRx editors, research stated, "To investigate chemo-mechanical effects of incorporating alkaline bioactive glass nanoparticles into a light-curable dental resin matrix. An unfilled Bis-GMA/TEGDMA material was infiltrated with up to 20 wt% of ultrafine SiO2-Na2O-CaO-P2O5-Bi2O3 particles."

Our news journalists obtained a quote from the research from Institute for Chemistry, "The unfilled and filled resins were investigated regarding their viscosity before setting and compared to commercially available materials. Set specimens were immersed for 21 days in phosphate buffered saline at 37 degrees C. Water uptake, pH, Knoop hardness, and degree of conversion of freshly polymerized and stored samples were investigated. Resin surfaces were viewed and mapped in a scanning electron microscope for the formation of calcium phosphate (Ca/P) precipitates. In addition, Raman spectroscopy was performed. Numeric values were statistically compared (p

According to the news editors, the research concluded: "A material with bioactive properties and similar hardness as the unfilled resin was obtained by incorporating 20 wt% of ultrafine SiO2-Na2O-CaO-P2O5-Bi2O3 particles into the resin matrix."
