Effect of mouthwashes on the color change of a self adhesive composite resin

Objective: Introduction of self-adhesive composites has greatly simplified the clinical procedural steps for composite restorations. Color stability is an important factor affecting the success of composite restorations. This study aimed to assess the color change of a self-adhesive and a conventional composite following immersion in mouthwashes. Methods: This in vitro, experimental study was performed on 48 discs fabricated of Grandio Flow (n=24) and Vertise Flow (n=24) composite resins. The baseline color parameters were measured using a spectrophotometer according to the CIE L*a*b* system. Samples of each composite were divided to three subgroups based on the types of study solutions, so they were immersed in chlorhexidine (CHX) mouthwash, fluoride mouthwash and distilled water (as the control group) for 24 hours. After that the color parameters of samples were measured again to determine the color change (?E). Data were analyzed using two way ANOVA and post-hoc Tukey tests at P=0.05 level of significance. Results: All samples showed color change but it was within the clinically acceptable range (?E<3.3) in all groups. The interaction effect of the type of composite and the type of solution on the ?E values was not significant (P=0.98). No significant differences were noted based on composite type (p=0.16) and staining solutions (p=0.79) regarding color change. Conclusions: The color change of Vertise Flow and Grandio Flow composites following immersion in CHX and fluoride mouthwashes for 24 hours, corresponding to 2 years of daily use of mouthwashes, was comparable to that in the control group (distilled water) and all of them were within the clinically acceptable range.
