title: [Colorimetric and opacity percentage study of dental restorative resins].
abstract: A colorimetric and opacity percentage study was carried out to compare experimental prototypes of resin at different die and additive concentrations with commercial prototypes. A simple and reproducible method was used. Through this study the optimum die and optical brightener formulas for a new dental resin were found and compared with available commercial dental resins in the national market.
