Abstract

For improvement of film thickness of final cementation, 2 brands (Shofu HY-BOND GLASS-IONOMER CX and GC Fuji-I) of Glass Ionomer Cement were milled and the experimental fine particlepowder was produced. Ohmae et al. reported the retention, total film thickness, and physical properties in aprevious study. In this study, the setting characteristics of these experimental cements, specific surface areaof particle, and disintegration rate were investigated. The results were as follows: Peak time of reaction ofexperimental cements using a differential scanning calorimeter were shorter than normal GICs. The startingpoint of dissappearance of fluidity of experimental cements using a thermomechanical analyzer were shorteras the perticle size became smaller. The specific surface area of experimental particle increased as theparticle size became smaller. The disintegration rate of experimental cements increased compared to normal GICs.
