Abstract
The fluorescence property of human teeth under UV light has long been studied in dentistry and is now used in the diagnosis of anomalies, such as dental decays. Its role in the appearance of teeth and dental restorations has also been demonstrated, and fluorescence, even under daylight, may sensibly modify the color of dental restorations. As such, dental resin composites used in aesthetic restorative dentistry include fluorescent agents which aim to reproduce the natural fluorescence of teeth. While several studies have measured the fluorescence properties of dental biomaterials and a few other studies have focused on predicting the color of samples, the influence of fluorescence on color prediction models remains to be assessed. In this paper, we propose a prediction model for the spectral emission of slices of a dental biomaterial as a function of their thicknesses, in reflection and in transmission modes, in order to improve color prediction models for these materials.
