Translucence parameters for 3 series of experimental hybrid composites were investigated using three-chromatic coordinates such as L* a* b* CHROMA technique using a type C illuminant geometry with the scope of 8o. The materials of each series contain in the same ratio different copolymers and a filler mixture (simple and mixed hydroxyapatite-ZrO2 or SiO2 powders and glass powders with barium oxide, respective strontium oxide, or quartz powder). The purpose was to determine the effect of filler composition of composites on translucence. The analysis shows that these materials have more or less translucence. CHROMA determinations indicate that for the composite that has as filler quartz microparticles anh hydroxyapatite nanoparticles, the translucence registered is higher. Results leading to the idea that chemical composition and the size of inorganic phase are important to obtain translucent composite materials that have very natural in appearance. Keywords: translucence, hybrid composites, CHROMA method.
