The effect of prepared denture cleansers on some physical properties of stained acrylic resin denture base material cured by two different techniques

Abstract

ABSTRACT
Background: The debris in the denture cause many problem to the patient and the use of the denture cleanser is the solution for this problem but this denture cleanser may affect the properties of the denture. The aim of our study was to observe the effect of prepared denture cleansers on some physical properties (water sorption, water solubility and color stability) of the acrylic resin after their immersion in the tea solution and also to compare the effect of those denture cleansers on heat and microwave cure acrylic resin.
Materials and methods: Heat curing and Microwave acrylic denture was prepared and immersed in four types of denture Cleansers after their staining with tea then the water sorption, water solubility and color stability of acrylic resin was measured .
Results: There were no changes in the stained acrylic properties when the samples were immersed in the prepared denture cleansers and in the alkaline peroxide cleanser compared to that immersed in the distilled water. Furthermore no significant differences were observed between microwave and water bath cured specimens in respect to color stability, sorption and solubility of the testing groups.
Conclusions: The prepared denture cleanser solutions are good and satisfactory cleanser materials for the acrylic resin denture base cured by two different techniques.
