Abstract AR
الهدف : الهدف من هذه الدراسة هو تقييم الاكساء المحروق (investment) و الرمل الأسود على الخشونة السطحية لمادة الاكريلك الحار.
المنهجية : تم تحضير 60 عينة من مادة الاكريلك الحار ثم قسمت العينات إلى ثلاثة مجاميع : 20 عينة (عينات قياسية) لمعت بمادة ال pumice و الماء ؛ 20 عينة تم تلميعها باستخدام مادة الاكساء المحروق و الماء و 20 عينة لمعت بالرمل الأسود و الماء.
إن معدل الخشونة السطحية للعينات بعد عملية التلميع كانت قد حددت بواسطة جهاز فحص الخشونة بروفيلوميتر.
النتائج : أظهرت النتائج بوجود فرق معنوي عالي بين المجاميع الثلاثة.
التوصيات : يمكن الاستنتاج بأن السطح الأنعم للعينات تم الحصول عليه بواسطة مادة الاكساء المحروق كان أعلى جدا من مادتي الرمل الأسود و ال pumice لذا مادة الاكساء المحروق يمكن أن تستعمل كمادة تلميع الاكريلك الحار المستخدمة في صناعة قاعدة طقم الأسنان عوضا عن مادة ال pumice.
Abstract EN
Objective: The aim of this study was to evaluate the effect of pumice, burning investment material and black sand on the surface roughness of heat cure acrylic resin.
Methodology: Sixty specimens were prepared from pink heat cure acrylic resin, the specimens where grouped into; 20 specimens which polished with pumice and water (control group); 20 specimens which polished with investment material (after burning it) and water; and 20 specimens which polished with black sand and water.
The average surface roughness of specimens after polishing procedure had been determined by profilometer (surface roughness tester).
Results: Through the application of ANOVA and LSD tests, the result of this study showed that there was a highly significant difference among the three groups at (P<0.001).
Recommendation: it may be concluded that the smoother surface of specimens gained by burning investment material was significantly higher than that of black sand and pumice materials.
So that burning investment material can be used as a polishing material for heat cure acrylic resin denture base instead of pumice material.
