| Abstract | ||
| In order to evaluate the effect of disinfectant solution on the hardness of acrylic denture base, chosen two types(sodium hypochlorite &chlorhexiden) in which thirty samples of acrylic resin of the same dimension were made and divided into 3 equal group(A:immersed into distilled water 24 hours) (B:immersed into chlorhexiden for 4 hours, after that 20 hours in distilled water) (C:immersed in sodium hypochlorite for 4 hours, after that 20 hours in distilled water) this process repeated foe 7 days. After measuring the surface hardness by using Brinell hardness test the result were highly significant between groups(A&B), (A&C) where as the difference was significant between group(B&C). From these finding & under the conditions of this study can conclude that those two materials had negative effect on the surface hardness of acrylic denture base materials | ||
