Abstract

Background: To evaluate in vitro the effect of three pediatric mouth rinses on the color stability of three different composite resins. Material and Methods: One 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<0.05). Results: All composite resin samples showed color changes after immersion in the different solutions studied. The ΔE* showed that pediatric mouth rinses produced significant changes in color of the composites tested. The group of nanohybrid resins presented lower levels of change in color stability (ΔE * = 4.63), followed by bulk resins (ΔE * = 5.70) and, finally, nanoparticle resins presented greater effects in color stability. (ΔE *= 5.84).
