ABSTRACT:
Dental composite filler materials comprise particles coated via an atomic layer deposition (ALD) process. The coating material has a different composition than the core particle. The difference in composition permits fine control over the refractive index of the coated particles, allowing good matching tooth enamel and to the binder materials used in the composite.
