|Title:||Development and evaluation of properties of a bioactive cement|
|Publisher:||JOURNAL OF POLYMER MATERIALS|
|Abstract:||The properties of a visible light cured bioactive cement developed using an organic resin binder bisphenol A-glycidyl methacrylate (BIS-GMA) and a fluoroaluminocalcium silicate glass have been studied. Bisphenol A-glycidyl methacrylate was synthesized by reacting diglycidyl ether of bisphenol A and methacrylic acid and characterized using infra red spectroscopy and high performance liquid chromatography. It was found to form a paste when incorporated with glass filler powder of 1 mu m particle size and could be cured into a hard cement when exposed to a light source of 440-480 nm wavelength for about 30-60 sec. Compressive strength, diametral tensile strength, transverse strength and Vickers microhardness have been measured for paste formulations containing 200 220 240 and 260 phr glass filler and compared. The concentration of photoinitiator has also been varied and its effect upon the properties studied.|
