摘要: Light-activated composites are now among the most popular dental restorative materials. Nevertheless, concerns exist about so-called depth of cure. Infrared spectroscopy (FTIR) has traditionally been used to quantify this problem by evaluating degree conversion resins. However, Raman scattering provides an alternate method. This article describes advantages and limitations micro-Raman spectroscopy, as compared FTIR other techniques, for calculating local cure light-cured composites.
