Principles of color science for appearance matching
This review will cover the major color science aspects that affect appearance matching, including calculation of color from spectral reflectance or transmittance, metamerism, translucency, technical differences in measuring equipment, effects of and interactions among mixed ingredients, and layering.
Attendees will understand the effects on visual appearance of basic optical properties of biomaterials being matched and will discuss the interactions of color science principles that affect an esthetic dental appearance.
Dr. Johnston is a Professor at The Ohio State University College of Dentistry and has research interests in the chemical and physical properties of dental biomaterials with an emphasis on the optical properties of esthetic biomaterials and the theoretical bases for determining optical characteristics.
