Abstract
With the constant evolution of tooth-colored restorative materials, evaluation of the material properties serves as a bridge between the fundamental material sciences and clinical applications. Although dental materials have undergone significant improvements, today’s methacrylate-based composites still have shortcomings that limit their applications. Two main motifs of these limitations involve the wear phenomena and polymerization stress. During polymerization, shrinkage may stress the adhesively placed tooth-colored restoration while it functions within the complex oral environment through mastication and temperature fluctuations .With the passage of time, wear, fatigue, and internal stress–strain from thermal contraction and expansion may create plastic deformation and marginal leakage and subsequently increase the risks of cuspal deflection, secondary-caries formation, and pulpal inflammation. Efforts to improve clinical performance and to diminish recurrent caries formation.Results: - Although there was increasing developments in the glass ionomer technologies, water absorption, color stability and marginal integrity are still a great problem associated with all modified glass ionomer restorative material. In addition to different health hazards of the red wine intake, it is approved that even it has a deteriorating effect on the restorative materials. It is obvious that there is a direct relation between the degree of water sorption of different resrorative materials and either color stability and marginal integrity. All resin based compsites in the present study have improper mariginal integrity varies from filling excess, cohesive failure, adhesive failure.
