“…[ 10 11 ] These changes can be evaluated by spectrophotometers, equipment that eliminates subjective interpretations by the naked eye,[ 11 17 ] and by CIE L*a*b* system, used to evaluate the color of dental materials.

Objectives:The objective of the study is to incorporate the nanostructured silver vanadate (AgVO3) decorated with silver nanoparticles at endodontic sealers AH Plus, Sealapex, Sealer 26, and Endofill, at concentrations of 2.5%, 5%, and 10%, and to evaluate physical-chemical properties.Materials and Methods:The study was to evaluate the radiopacity using digital radiography (n = 5), the tooth color change in 48 incisors (n = 3) for 7, 30, 90, and 180 days in a spectrophotometer, and the topographic distribution in a confocal laser (n = 5). The radiopacity was analyzed by Kruskal–Wallis test and the permutation (α = 0.05) and the color and topographical distribution by descriptive statistical analysis.Results:The AgVO3 had no effect on the radiopacity of Endofill and Sealapex (P > 0.05) and at 2.5% concentrations increased the radiopacity of Sealer 26 and AH Plus (P < 0.05). The Endofill 10% showed less color change, and the major changes were the modified groups in 180 days. The AgVO3 showed a circular topographic distribution in areas of the sealers.Conclusion:It was found that the addition of AgVO3 did not affect the radiopacity of Endofill and Sealapex however, increased the radipacity of Sealer 26 and AH Plus. For modified groups, the greatest color change was promoted after 180 days, except for Endofill with 10%. Topographic distribution of nanomaterial affected the color change of theevaluated sealers.

“…Invitro study by Çağrı Ural et al 2016 showed that the color change of both light cure and dual cure adhesive resin cement were within clinically accepted level also, third-generation adhesive resin cements with free tertiary amines and benzoyl peroxide underwent smaller color changes than the light-and dual-cure resin materials 3 Marchionatti et al 2017 concluded that The light-and dualpolymerizing modes presented similar color changes for all evaluated periods (2, 6, 12, and 24 months). 20 Also, Ah-Rang Kim, et al 2015 said that the color change of selfcure and dual cure adhesive resin cement caused by the amine group 21 Also, Evren Kilinc et al 2011 concluded that all resin cements did not cause a noticeable color change on the ceramic, which also showed that even a significant color change of the resin cement may be unnoticeable when covered by the ceramic. 2…”

Statement of the problem The increased thickness of ceramic laminate veneer with butt joint design at the incisal edge reduce the amount of light reaching the cement layer and therefore compromise photo-activation of the luting material However, an adequate cure of the resin-based cement is an important prerequisite for the stability and biocompatibility of the restoration. 57 Dual-cure resin-based cements have been recommended for luting ceramic laminate veneers to compensate for the attenuation of the curing light effected by the thickness of restoration and to allow complete polymerization of the luting material even at the incisal area of laminate veneers where access for the curing light is limited, but the yellowish discoloration due to ageing of conventional dual-cure resin based cement was the problem. Purpose : The aim of this study was to evaluate color stability of e-max CAD veneers cemented with light cure and dual cure amine free adhesive resin cement (Base line), (After 2 months), (After 4 months), (After 6 months),(After 8 m) Materials and methods: A total of 22 ceramic laminate veneers restorations(11 e.max cad cemented with light cure adhesive resin cement and 11 e.maxcad cemented with dual cure adhesive resin cement) were included in the study and completed by one operator (the researcher) who followed a meticulous clinical procedure and the ceramic laminate veneers were fabricated by one experienced dental technician. The operator followed the five phases of laminate veneers fabrication: diagnosis, preparation design, provisionalization , construction of the material and bonding ,Follow up sessions were done every two month for each patient using operator vision to evaluated change in color and then confirmed with easyshade in the baseline, 24 hours post cementation and in the postoperative follow-up according to the modified USPHS (United States Public Health Service) criteria. This was performed by an experienced, blinded investigator. Data were recorded, tabulated, and statistically analyzed using the Chi-square test and the significance level was set at P ≤ 0.05. Results: There was no statistically significant difference between (Group I) and (Group II) where (p=1) as both groups showed (100%) Alpha in all time periods. Conclusion: Both E.max CAD laminate veneers cemented with light cure and E.max CAD laminate veneers cemented with dual cure amine free adhesive resin cement revealed high successful survival rate in terms of the stability of the color.

“…However, especially for veneers, the use of purely light curing flowable composites was described, because a chemical initiating system used in the dual curing products was claimed to have a tendency for discoloration over time. However, recently no difference was found in a clinical study related to color stability between a light cured resin composite and a dual curing luting material [40]. If veneers are luted with light curing only materials, the optimal quality of cure (polymerization) has to be guaranteed.…”

Color stability of ceramic laminate veneers cemented with light-polymerizing and dual-polymerizing luting agent: A split-mouth randomized clinical trial

Abstract: The color stability of ceramic laminate veneers was similar for both of the polymerizing modes for all evaluated periods. Marginal discoloration increased over a 2-year period for both the light- and the dual-polymerizing modes.
