Computational Prediction of Tooth Shades in Direct Restorations with Composite Resins

National audienceThe VITA shade guide is a dental instrument that allows accurate and secure determination of tooth color and shade, which constitutes one of the most important but still complex aspects of dental restorations in aesthetics dentistry. In this study, we survey the modern literature in color matching techniques and discuss a logistic regression approach for computational prediction and selection of tooth color in direct restorations using dental composite resins. Test cases were obtained at the school of dentistry of Universidad Central de Venezuela and were further analyzed in a personal computer through the capabilities of the Wolfram language's built-in machine learning package in Mathematica. Altogether, our results exhibit significantly high accuracy rates in front of the classification problem under study, thus emphasizing the impact of this sort of models in current aesthetics dentistry
