Purpose. The purpose of this in vitro study was to analyze the influence of thermocycling on the color of CAD-CAM materials with underlying resin cement. . Material and methods. Seven different CAD-CAM materials, composite resins and glass-ceramics were cut into 0.7-mm and 1.2-mm thicknesses (n=10) and cemented with a dual-polymerizing resin cement, a light-polymerizing resin cement, and a preheated composite resin (N=420). Color values were measured by using spectrophotometry. Specimens were subjected to thermocycling (5 degrees C and 55 degrees C; 5000 cycles). The measured color difference (Delta E) data were analyzed by using descriptive statistics. Normality of data distribution was tested by using the Kolmogorov-Smirnov test. Three-way and 1-way ANOVA followed by the Scheffe post hoc test and unpaired 2-sample Student t test were computed to determine the significant differences among the tested parameters (alpha=.05). Results. Delta E values were significantly influenced by the CAD-CAM material (eta(2)(p)=0.85, P |
