Effect of Common Drinks on the Color Stability of Microhybrid and Nanohybrid Composites in Children
Journal Title: مجله دانشکده دندانپزشکی مشهد - Year 2013, Vol 37, Issue 2
Abstract
Introduction: In spite of numerous developments in resin composites products, their color stability is still a major problem particularly in pediatric dentistry, since frequent visits of children is of great importantance due to their behavior management, regardless of the problems pertaining to aesthetic and additional expenses. The purpose of this study was to evaluate the effect of common children drinks on the color stability of nanohybrid and microhybrid resin composites. Materials & Methods: In this experimental study, 80 disk samples (with diameter of 10 mm and depth of 2 mm) of microhybrid (point4 Kerr) and nanohybrid (Herculite XRV Ultra Kerr) resin composites were prepared. (categorized in 2 groups of 40).Then the samples of each group were divided into five subgroups of eight and were immersed in five different solutions (orange juice, red grape juice, fanta coke, chocolate milk) and distilled water as the control group for 4 hours daily for a period of 10 days. The color of samples was measured by a spectrophotometer at the beginning of the study and after staining using CIE lab system. The data were analysed by 2-Way ANOVA test. Results: 2-Way ANOVA showed that there was no significant statistical difference between the microhybrid (P4) and nanohybrid (HCU) resin composites with respect to the degree of staining in the mentioned solutions (P=0.29). Moreover 2-way ANOVA showed that type of the drink has a significant effect on the degree of staining of materials (P< 0.001). Conclusions: It doesn’t seem that the new nanocomposites have any considerable advantage to microhybrid resin composites regarding staining. Also regarding these results, colored drinks especially red grape juice and chocolate milk are not recommended in the first days after composite filling.
