Effect of pediatric mouthwashes on the color stability of dental restorations with composite resins. In vitro comparative study

BackgroundTo evaluate in vitro the effect of three pediatric mouth rinses on the color stability of three different composite resins. Material and MethodsOne hundred thirty-two disc-shaped samples (n = 132) were prepared, with 44 for each type of composite resin (n = 44), and the initial color values were measured with a spectrophotometer. Eleven (n= 11) samples were placed in each immersion substance, and 3 types of pediatric mouthwashes were used with distilled water as a control. The samples were placed in an incubator at 37°C for one hour (equivalent to 1 month of mouthwash use). and color measurement was performed. Color change values (ΔE*) were obtained and the results were statistically analyzed. Kruskal Wallis and Mann-Whitney U tests were used to compare the values between groups (P
