Abstract
Background: Denture cleaner solutions are used extensively for the cleaning of prosthesis both plastic and metallic component .The chemical composition of cleaner solution are virtually important in defining their adverse effect on properties of acrylic part of prosthesis Aims of the study The present study carried out to study the effect of some cleaning solution on tensile strength and indentation hardness of both types of acrylic resin (hot and cold cured) and compare the effect on different types of denture materials. Materials and methods: Specimens of hot and cold cured acrylic resin were prepared according to ADA specification for both indentation hardness and tensile strength test. The specimen were immersed in distilled water for seven days then were left in containers containing one of the following denture cleaners, Staradent 1%H202, 5%HCL& vinegar solution. Each container contained five specimens of either heat cure or cold cure with one type of denture cleaners and they were left for seven days. Specimens were then tested for indentation hardness and tensile strength test. Results: The results showed that Vinegar solution has an deleterious effect on tensile strength and indentation surface hardness of hot cured acrylic resin as compared with control while for cold cure all specimens affected by all cleaning solutions.
