Popis: Objective: Mouthwashes containing chlorhexidine can cause discoloration in restorative materials when used for the long-term. To prevent staining of a restorative material, several protective materials are used. The aim of this in vitro study was to evaluate the impact of a surface sealant on the color stability of a nano-hybrid composite resin material immersed in different mouthwashes.Methods: A total of 42 composite resin discs (10 x 2 mm) were prepared with a nano-hybrid composite resin (Herculite XRV Ultra) using Teflon moulds. The composite specimens were first divided into two groups (with or without a surface sealant) then into three subgroups (n = 7) according to the mouthwashes (Gengigel, Oderol, and Klorhex). After SS application to 21 specimens, all the discs were subjected to baseline color measurements using a spectrophotometer according to the CIE L*a*b* system. The specimens underwent thermal cycling. Following immersion in different mouthwashes for 24 hours, the color measurements were repeated. The ΔE data were assessed using Kruskal-Wallis one-way ANOVA. Mann-Whitney U test was performed for different immersion mouthwashes (p0.05) between the sealed and unsealed composite specimens in terms of the color changes.Conclusion: The application of a low viscosity liquid surface sealant material did not show the expected effect on the color stability of a nano-hybrid composite resin in terms of three different mouthwashes.Keywords: Color change, mouthwash, surface sealant, composite resin, thermal cycling
