Abstract

ABSTRACT: Purpose: To investigate colour agreement between different shades of Panavia V5 resin cement and their try‐in pastes under zirconia‐reinforced lithium silicate ceramics. Methods: Forty‐four zirconia‐reinforced lithium silicate ceramic specimens were prepared at 0.8 ± 0.01 mm thickness. Composite resin tooth‐shaded background specimens were obtained in two shades. Resin cement specimens were fabricated at 0.1‐mm thickness. Colour difference values (Δ E ) between Aquagel and both the try‐in paste and resin cement were calculated using the CIE‐Lab system. The CIEDE2000 (ΔE00) colour formula was used to determine colour differences. The three‐way ANOVA test and a multiple comparisons test were used for statistical analysis ( α = 0.05). Results: A statistically significant difference was found between the ΔE00 values obtained from the cement shade colour measurements for all specimens ( P < 0.05). According to the three‐way ANOVA test, lower ΔE00 values were observed in the try‐in paste group compared to the resin cement group. The ΔE00 values were significantly affected by the cement shade and tooth‐shaded background ( P < 0.05). Conclusions: The colour agreement between the try‐in pastes and the corresponding resin cement differed, and the try‐in pastes could not mask the dark dental background as much as the corresponding resin cement.
