Özet
We investigated the short-term (4 weeks) color stability of light-cure and dual-cure resin cements. Sixty disk-shaped test specimens of adhesive resin cement (10 x 1 mm) were prepared. One feldspathic porcelain test specimen (12 x 14 x 0.8 mm) was prepared from a prefabricated ceramic block. The feldspathic sample was placed on the resin cement disk and all the measurements were performed without cementation. Specific color coordinate differences (Delta L, Delta a, and Delta b), and the total color differences (Delta E) were calculated after immersion in distilled water for different periods. Data were compared using one-way analysis of variance (ANOVA) (alpha = 0.05). The test results revealed that different chemical structures and curing modes affected the Delta E values (P < 0.05). The highest Delta E values were obtained for RelyX Unicem dual-cure cement (2.14 +/- 0.40), and the lowest for NX3 light-cure cement (0.78 +/- 0.34). Third generation adhesive resin cement free of tertiary amines and benzoyl peroxide showed relatively slight color change in both test groups (light-cure and dual cure resin cement).
