Optical properties of composite restorations influenced by dissimilar dentin restoratives

High esthetic requirements present a challenge in restorative dentistry due to the complex structure of dental tissues. This complexity is reflected in the specific micro-morphology, variable thickness, anisotropic and polychromatic nature as well as different composition of enamel and dentin [1,2]. The characteristic layout of enamel prisms and dentinal tubules and different amounts of organic substance cause differences in the optical parameters of these two tissues. Optical properties of contemporary composite restorations and natural teeth, despite differences in chemical composition and micro-structure, contribute to excellent esthetic results [1 –4].
