The Effect of Newly Prepared Cleansing Agent on The Surface Roughness and Tensile Strength of Highly Impact Acrylic Denture Base Material

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)
