Abstract

The evaluation of the characteristics of a dental restorative material is based on several criteria such as the ability of the material to resist to potential degradation, its durability, the stress it exerts on the residual dental structures, its resistance to surface wear, and its resistance to fracture. All these important factors must be taken into account and tested when developing a new dental restorative material. Glass ionomer cements (GIC) possess unique properties, including adhesion to tooth structure, bioactivity and fluoride release. The objective of this study is to evaluate by analyzing the dynamics of the polarized speckle field how GIC samples, prepared according to two different methods and conserved in water at 35°C, deteriorate.
