[Effect of light cured sealants for occlusal surfaces on discoloration and plaque accumulation on removable partial dentures].
According to increased surface hardness and decreased solubility, as revealed in laboratory tests, an improved surface-quality of denture-base polymers after glazing with light-polymerized acrylic coating materials could be expected. However, in the present clinical study on 150 dentures half-side treated with light activated coating materials, already after 3 months of use the coated denture-halfs showed more frequently discolouration and increased plaqueaccumulation in comparison with the uncoated control-sides. Scanning microscopic examination revealed an increasing roughness of the glazed surfaces during period of use.
