摘要：

Glass-ionomer cements (GIC) belong to the class of materials known as acid-base cements. The drying process of these materials and the evolution of their physical properties play an important role in the quality and durability of dental care. Since monitoring these processes contributes to the improvement of the knowledge on these materials, we aim in our work to monitor in real-time hardening of GIC using dynamic speckle. Speckle images are temporally analyzed by computing the temporal correlation coefficient. The temporal correlation curves present a Lorentzian profile, which characteristics vary during GIC hardening process.
