Research Paper (postgraduate) from the year 2012 in the subject Chemistry – Other, grade: 3, , language: English, abstract: Aims: To evaluate the effect of two prepared and commercial solution on surface roughness and tensile strength of highly impact acrylic denture base material Materials and Methods: The total number of specimens were one hundred and fifty. They were prepared from highly impact acrylic and subdivided into five groups for each solution (EDTA, Soda+H2O2, Lacalut, Corega and distilled water). Two laboratory tests were used for this research. Surface Roughness and tensile strength test. The surface roughness test specimens were constructed with dimensions (10×10×2±0.03mm) (length, width, and thickness respectively). According to ADA specification no.12 the tensile test specimens were constructed with dimensions 90×10×3±0.03mm (length, width, and thickness respectively). The immersion periods in this research are (2 day, 7 day and one month). ANOVA and Duncan multiple range test were used. The statistical results were considered significant at p ≤ 0.05. Results: the results showed that (soda+H2O2) has no significant change on the surface roughness and tensile strength of highly impact acrylic denture base material in (2d ay, 7 day, and 1 month) conclusion: (soda+H2O2) has the lowest effect on the surface roughness and tensile strength of highly impact acrylic denture base material in (2 day, 7 day, and 1 month)
Key words: denture cleanser, highly impact, lacalut
