Effects of different children health drinks on stainability of anterior tooth colored restorative materials-an in vitro study

The aim of this in vitro study was to evaluate the color stability of various anterior tooth-colored restorative materials by children′s health drinks. Totally, 168 spherical shaped specimens of dimension of 12 mm in diameter and 1.2 mm in thickness were prepared from compomer (Dyract), resin modified glass ionomer (Vitremer), resin composite (Filtek Z350). Each group of 56 specimens of each material were divided into seven subgroups. Each subgroup was stored in a different solution (distilled water, milk, milk with sugar and bournvita, milk with sugar and horlicks, milk with sugar and boost, milk with sugar and complan, milk with sugar and maltova) for 48 h. The color change measurement was done using spectrophotometer (Minolta, CM-3301d) both before and after staining. For each group mean values (ΔEFNx01) were calculated, and inter-comparison between health drinks and materials was done using one-way ANOVA. Intercomparison between materials was done with Tukey′s post -hoc test. The level of significance for all the tests was chosen as P < 0.001. Resin composite showed the highest resistance to staining, and resin modified glass ionomer showed the least resistance. For all the materials, exposure to bournvita and boost resulted in high rates of color change than exposure to complan, maltova, horlicks, milk, and distilled water. All the health drinks tested did not show any visible effect on any of the esthetic restorative materials taken for study.
