Abstract

An experiment using a gloss meter and a spectrophotometer was performed to elucidate the effects of surface texture on the glossiness and color stability of porcelains. Opaque porcelain (opaque), body porcelain (body), incisal porcelain (incisal) were used, and the effects of surface texture obtained by finishing with #150, #600, #2000 waterproof abrasive paper and by puff polishing with colloidalsilica having a particle size of 0.06 μm on glossiness and color stability were determined. The following conclusions were reached.<BR>1. The golssiness of the porcelain varied among opaque, body, and incisal, and increased as the surface texture became finer.<BR>2. As to the color stability of porcelains with surface texture obtained by various methods, L* and b* were the highest in opaque, followed by body, and then incisal, but no significant differences were noted for a*.<BR>3. As for the color stability of porcelain, L* decreased and b* increasedas the surface texture became finer in opaque, body, and incisal, but no significant differences were observed for a*.
