Disclosed herein are methods for creating opalescence in dental materials and restorations, compositions used in such methods, and the resultant dental materials and restorations. More particularly, the opalescence may be created by directly embedding opalescent particles into a matrix material. In some embodiments, photonic crystals are embedded in the dental material to achieve the opalescent effect. Photonic crystal particles may be embedded in dental materials matrices such as ceramics, composites, and polymers, and can generate opalescence in the materials. Some embodiments disclose compositions for applying the opalescence to a dental restoration.

A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.
