| Abstract | ||
| Objective: In order to evaluate the effect of different typed of Separating Medium on the roughness of the fitted tissue surface of acrylic denture base. Methodology: Chosen three types of separating medium (Group A Tin foil), (Group B Detery Isolant),(Group C Cold Mould Seal),used 30 samples of hot cure acrylic resin ,10 samples for each group, after complete curing of these samples , Profilometer device was used to measure the surface roughness of each sample in all groups. Results: Using One Way ANOVA Test and LSD test, the results were highly significant in differences among all groups. Although (Group A) showing lest roughness, (Group B) showing a satisfactory result of roughness, While (Group C) Showing the highest unsatisfactory surface roughness of acrylic denture base. Recommendations: make other studies on the effect of different separating medium on other properties of the fitted tissue surface of acrylic denture base such as hardness. | ||
