Effect of Water Absorption on Color Stability of Different Resin Based Restorative Materials in Vitro Study
International Journal of Composite Materials
This study was designed to evaluate the effect of water absorption of three resin based composite materials on their color stability Methods: using scanning spectrophotometer. A total of 45 disc samples were constructed from microhybrid resin composite, polyacid modified resin composite and giomer. It should be mentioned that the selected shade is A2. Then inserted in water for water absorption test. Using five different drink [mouth rinse (37•C) (Chlorohexidine containing mouthwash), tea,doi:10.5923/j.cmaterials.20120202.02 fatcat:r67y56sgujfd7k3jeufrexlbei
