ABSTRACT:
A temporary cosmetic dental coating has a transparent resin matrix containing embedded glass microspheres. The refractive index of the microspheres is at least 0.03 greater than the refractive index of the transparent resin matrix. Incoming light is reflected back in the same direction as it was emanated, providing a lustrous dental coating that is cosmetically appealing and covers dental defects and discoloration. The transparent resin matrix with glass microspheres is formed by mixing together a methacrylate based liquid monomer of methyl methacrylate or BIS-GMA and glass microspheres coated with activators/catalysts. The user applies the mixed composition to the teeth to form a temporary cosmetic dental coating, which is readily removed using a dental pick. A lac resin dissolved in ethyl alcohol is optionally mixed with glass microspheres and applied to teeth surfaces. The coating is hardened by alcohol evaporation and removed by alcohol dissolution.
