Abstract
ObjectivesWe characterized the optical properties, such as absorbance and fluorescence, of dental resins containing quantum dots (QD). We also determined the doping level needed to obtain a broad and nearly flat emission spectrum that provides the perception of white color.MethodsThe samples studied were resin composites from Charisma (Heraeus Kulzer) prepared with CdSe/ZnS core–shell QD (0.05–0.77 mass%).ResultsThe results showed that the fluorescence of dental resin composites can be tailored by using CdSe/ZnS core–shell quantum dots.ConclusionQD core incorporation into dental resins allows the fabrication of restorative materials with fluorescence properties that closely match those of natural human teeth.
