Özet

Aim: The aim of this study is to determine the effect of resin-based coating agent on the color change of high viscosity glassionomer cement (HVGIC) in four different pediatric drugs.

Materials and Methods: A high viscosity glass-ionomercement restorative material and a nanofilled resin-basedcoating were studied. Disc-shaped specimens (2x5 mm) wereprepared and divided into two groups, noncoated and coated(n=24). Then the specimens were subdivided into four groupsaccording to their storage media; antibiotic, analgesic, vitamin and a herbal cough syrup (n=6). Specimens immersed in storage media for two min 3 times a day for 1 week. Betweenimmersion periods, the samples were stored in distilled water. Baseline color values were calculated based on theInternational Commission on Illumination (CIE) L*a*b* system, by using a spectrophotometer. After 7 days, ΔE valueswere calculated. Twoway ANOVA test was used for dataanalysis.

Results: The mean color changes (ΔE) varied in the range of averaged 1.48–3.74 for all groups. Among the coated anduncoated groups, only the ΔE value of the coated-group, which was kept in antibiotics, was found to be statisticallysignificantly higher (p = 0.004). When the difference betweenthe drugs used in the same group (coated/ uncoated) wasevaluated, it was observed that while there was no significant difference in the uncoated group, the color change in theantibiotic group with coat was significantly higher than that of vitamins and cough syrup.

Conclusion: The application of coating agent on HVGIC had no significant effect on color stability. It has been shown thatcolor changes due to drug groups may also depend on the size and structure of the coloring particles, apart from the pH of thedrug.
