An In Vitro Staining Effect of Different Children's Health Drinks on Esthetic Restorative Materials

To evaluate the staining effect of different children's health drinks (Boost, Complan, and Pediasure) on esthetic restorative materials (giomer, nanohybrid composite, and ormocer). The specimens consist of giomer, nanohybrid composite, and ormocer. Before the discoloration process, 80 disks of each material were fabricated, each measuring 5 mm in diameter and 2 mm in thickness. These disks were then measured for lightness*red/green*blue/yellow (L*a*b*) values. Around 10 samples from each subgroup were then submerged in each of the four staining solutions. Analysis of discoloration levels was done at baseline and 48 hours after immersion in the staining solution. Each specimen's staining effect was evaluated using a spectrophotometer.Each specimen's L*a*b* values were measured three times by placing it on the measurement head. The internal energy (ΔE) unit, which expresses resistance to the staining effect, was derived using each specimen's L*a*b* values. All the tested materials showed a color change. However, giomer showed greater ΔE values compared to nanohybrid composite and ormocer. Of all the immersion media used, Boost samples resulted in the highest color change, followed by Complan, Pediasure, and milk. Out of the three restorative materials used in the study, ormocer showed more resistance to color change than nanohybrid composite and giomer with all the tested media.
