    Author(s): Sundus Abdul Alhussain Jasim and Shorouq M Abass*

    Objective: The objective of the study was to investigate the effect of immersion in different disinfectant solutions, on hardness and surface roughness of a heat-cured acrylic resin. Materials and Methods: Specimens were immersed in distilled water, commercial alum in concentration 5%,10% and sodium hypochlorite1% for 60 hour and 180 hours (n=10). After periods of immersion, shore hardness and surface roughness were evaluated using shore D hardness tester (time TH210 shore D hardness tester) and roughness tester, respectively. The data were analyzed using one-way ANOVA and Tukey HSD test, at a level of significance of 5%. Results: The hardness mean values ranged from 82.856± 1.674 to 86.653 ± 1.226 and roughness main values from 0.177± 0.139to 1.923± 0.510. There is no difference in hardness and roughness between groups and times (p>0.05). Conclusions: W.. Read More»
