Some properties of a denture acrylic coating

Abstract

The water sorption, solubility, hardness, and color stability of thin specimens of autopolymerized and heat-polymerized denture base polymers with and without a UV light-polymerized coating material were investigated. The specimens were saturated after storage in water for 24 h. The thin coating reduced the leakage of soluble ingredients from an autopolymerized denture base material. The coated materials had increased surface hardness compared with the uncoated, but the difference in hardness was reduced on water uptake. A continuous increase in yellowing of the auto-polymerized coated and uncoated specimens was observed when stored in water at 37°C.
