Temporary cements are sold by many companies for use in cementing provisional prosthodontic appliance. However, as there is usually a color clifference between temporary cements and resin temporary crowns, the color of the semi-transparent resin is often affected by the temporary cement, making it difficult to make a good color match.In this study, we made photoelectric colorimetrical measurements of the colors of self-curing resin and eighteen kinds of temporary cements using a CIE L^*a^*b^* color system, and we evaluated the change of color after application of each cement to resin. The results were as follows ; 1. The color of resin temporary crowns was affected by all the temporary cements. 2. Although all the temporary cements differed in color from each other, the colors of three of the temporary cements, Neodyne α, Hy-Bond temporary cement (soft) and Impression paste, differed especially from the rest. 3. Opotow Temporary cements, Propack, and Nogenol Tetnporary Cement showed the greatest color-difference values.
