Abstract

The surface roughness of denture base fabricated with Acrylic resin is crucial in the maintenance of denture hygiene. Rough surfaces are found to accumulate microorganisms which can colonise the microirregularities leading to foul smell and also compromise the health of the oral tissues. This Study was aimed to measure the surface roughness and flexural strength of heat polymerised resin of 180 day use after its immersion in denture cleanser. Two types of heat polymerised acrylic resins Acryln – H and DPI were selected. 40

specimens were prepared out of each resins. Amoung 40 specimens 20 specimens are taken as a control from each of the resins. Then the specimens were immersed in distilled water and in denture cleansing tablet sodium perborate monohydrate. Surface roughness (RA) and flexural strength (S) was measured before and after immersion in denture cleanser solution.The surface roughness were increased in both Acryln-H and DPI heat cure acylic resin materials after immersion in denture cleansers. The flexural strength were much reduced in Acryln-H material on comparing with DPI after immersion in denture cleanser.
