Recently, shade matching between the teeth and dental porcelain has been investigated in the field of esthetic dentistry. This study compared two types of spectrocolorimeters, a precise machine (HITACHI color analyzer 607) and simple machine (Dental color analyzer), for studying the color of Vita dental porcelain. Our conclusions are as follows : 1. X, Y, Z values of porcelain after baking dentin were larger than those after baking enamel in the case of using color analyzer 607, while X, Y, Z values using Dental color analyzer recorded reverse order. 2. CIE color coordinates of porcelain after baking enamel were approached a neutral point. 3. It was difficult to decide color of C shade in the case of using Dental color analyzer. 4. CIE a^*b^* color coordinates recorded lower values after baking enamel than after baking dentin. 5. Dental color analyzer has high reliability and usability.
