Abstract
This study atlempted to develop a resin cement with high adhesive and compressive strength and low disintegration.Therefore, adhesive cyclophosphazene monomer was synthesized.Four kinds of cements were prepared the using the synthesized monomer, then the tensile adhesive strength between cement and bovine dentin or three kinds of dentin alloy as well as the compressive strength disintegration were measured.Among four kinds of cements, the best results for adhesive strength, compressive strength and disinitegration were obtained when the liquid composition consisted of 60wt% monomer, 38wt% HEMA and 2wt% polyacrylic acid.The adhesive strength between the synthesized monomer and bovine enamel and bovine dentin was 5.2MPa and 3.7MPa, respectively.It was 38.3MPa for Co-Cr alloy, 27.9MPa for Ag-Pd-Au alloy, 24.8MPa for 18 Karat gold alloy.Compressive strength and disintegration were 210MPa and 0.23%, respectively.
