Final esthetic result of ceramic restorations cemented with different colors of cement

Abstract

Objective The purpose of this study is to evaluate the color changes of lithium disilicate ceramics when cemented with different brands of cement by varying the thickness of the ceramic. Materials and Methods Forty ceramic discs, shade A2, were fabricated with 0.5 and 0.8 mm thickness. Forty composite resin discs, shade A3, were also produced. The ceramic samples were cemented to the composite resin discs, with two colors of resin cement, Neutral and Warm. A spectrophotometer evaluation was made. Translucency and color change analysis was performed by calculating the ΔE. A two‐way analysis of variance test and multiple comparisons were performed using the Bonferroni method with a 95% confidence interval. Results There are statistically significant differences between the two ceramic thicknesses with different brands of cement (p < .001). In addition, using the translucency analysis it was found that there are statistically significant differences between the two ceramic thicknesses in both types of cement (p < .001). Conclusions The use of different cementation materials on lithium disilicate ceramics appears to have little visible influence at the clinical level. Different ceramic thicknesses have a clinically visible influence on the final restoration color.

Color Assessment of Feldspathic Ceramic with Two Different Thicknesses, Using Multiple Polymeric Cements

“…Furthermore, these results suggest that the ceramic’s thickness variation influences the final color of the restoration. These clinical detectable differences are in agreement with Xing et al [ 67 ], Pires et al [ 47 ], Igiel et al [ 21 ], Czigola et al [ 69 ], Tamam et al [ 44 ], Carrabba et al [ 41 ] and Gomes et al [ 70 ].…”

“…This suggests that there is a clinically visible color change when varying the cement, as Xing et al [ 67 ], Pires et al [ 47 ], Dede et al [ 68 ], Pissaia et al [ 27 ], Czigola et al [ 69 ], Gugelmin et al [ 54 ], Hoorizad et al [ 49 ] and Carrabba et al [ 41 ] stated. In a previous study conducted by our team, Gomes et al [ 70 ] concluded, like Tabatabaei et al [ 71 ], that there is a clinically detectable difference between cements.…”

Color stability of dual‐cured and light‐cured resin cements: A systematic review and meta‐analysis of in vitro studies

“…Then, 44 studies remained for full-text evaluation. From these, 17 studies were excluded because of several reasons (Table S2): (11) there was no comparison between light-cure and dual-cured resin cements, [14][15][16][17][18][19][20][21][22][23][24] (3) the full-text of the manuscript could not be retrieved, [25][26][27] (2) did not use any aging method, 28,29 and (1) was in Chinese. 30 The qualitative analysis was performed on a total of 27 articles.…”
