Effect of toothbrushing on color changes of esthetic restorative materials.
OBJECTIVE
The aim of this study was to evaluate the effects of various drinks and toothbrushing on the color changes of esthetic restorative materials used in pediatric dentistry.


METHODS
Forty specimens were prepared from each of three restorative materials (compomer [Dyract AP], glass ionomer cement [Ionofil Molar AC, Voco], composite resin [Filtek Z 250]). Specimens were divided into four groups for immersion in three different staining solutions (cherry juice, cola, chocolate milk) and distilled water. Each group was subdivided into brushing and non-brushing groups. The specimens in the brushing subgroups were brushed with toothpaste once a day using an electric toothbrush. Color was measured using a colorimeter, and color changes were calculated between baseline and 1, 7, 30, 60 days. Data was analyzed using Kruskal-Wallis, Mann-Whitney U, Wilcoxon, and Wilcoxon Signed Rank tests.


RESULTS
All the solutions evaluated yielded color changes, and these changes were significantly greater for composite resin than for glass ionomer cement or compomer (p < 0.006). Brushing significantly decreased the color changes of restorative materials (p < 0.004).


CONCLUSIONS
Brushing significantly influenced the color stability of esthetic restorative materials. The results of this study also showed that glass ionomer cements and compomers had higher color stability than composite resins.


CONCLUSIONS
The color stability values after brushing may better reflect the discoloration of the esthetic restorative materials. Any color stability study model should consider the effects of toothbrushing that can remove the adsorbed colorants. The results of this study also showed that glass ionomer cements and compomers can be used in anterior restorations of children with their higher color stability than composite resins.
