The effect of denture cleansers on surface roughness and microhardness of stained light cured denture base material

الملخص EN

Background: Denture cleansing is the most widely used method by the patients to maintain clean and health denture but the prolonged use of such cleansers may affect the properties of the denture.

The aim of this study was to observe the effect of denture cleansers on surface hardness and surface roughness of the light cured acrylic resin after their immersion in tea solution.

Materials and methods: Light curing acrylic resin was prepared and immersed in four types of denture cleansers after staining with tea then surface hardness and surface roughness of the acrylic resin was measured.

Results: There is no change in the stained acrylic properties when the samples were immersed in the denture cleansers compared to that immersed in the distilled water.

Conclusions: The prepared denture cleanser solutions are satisfactory for the acrylic resin denture base.

It is recommended to use the denture cleanser for cleansing the prostheses which were cured by light curing method.

Key words: Denture cleanser, surface hardness and roughness, light cured resin.
