Studies on optical properties of two commercial visible-light-cured composite resins by diffuse reflectance measurements.

abstract：:Earlier work revealed that creep of a particular dental amalgam can be described by the model F(t) = F0 exp (t/t0)m. Here F(t) is the creep compliance at time t, whereas F0, t0 and m are constants of the model. In the previous study only three alloys were used. It was the aim of this study to investigate the factor al...
