| Summary: | 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+HR2ROR2R, Lacalut, Corega and distilled water). Two la-boratory 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 con-structed with dimensions 90×10×3±0.03mm (length, width, and thickness respectively). The immersion periods in this research are (2day, 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+HR2ROR2R) has no significant change on the surface roughness and tensile strength of highly impact acrylic denture base material in (2day, 7 day, and 1month). Conclusion: (soda+HR2ROR2R) has the lowest effect on the surface roughness and tensile strength of highly impact acrylic denture base material in (2day, 7 day, and 1month |
