Abstract

Objective: The aim of this in vitro study was to evaluate the surface roughness of heat-cured acrylic resin after immersion in artificial saliva and different solutions. Materials and Methods: 70-disc shaped specimens 10mm in diameter and 2 mm in thickness were prepared from heat-cured acrylic resin. Then, divided into 2 groups. First group consist of 4 groups as follow: (control) immersion in distilled water, immersion in Zamzam water, immersion in diluted thyme oil and immersion in mouth wash (Listerine ®) with 10 samples each. The samples were immersed in their respective solution for 8 h per day during one month. The second group consist of 3 groups as follow distilled water, artificial saliva normal and acidic with 10 samples each. The samples kept in artificial saliva for 16h per day during one month. Profilometer was used to evaluate the surface roughness(µm). For analyzing statistically, the obtained data, one-way ANOVA and LSD test were used. P-value<0.05 was considered significant. Results: All solutions showed no statistically significant difference on surface roughness of specimens at 8h and 16h for one month. However, the Zamzam water group showed positively significant difference when immerse 8h for one month. Conclusion: The six solutions used in this study none produced increased in surface roughness compared to control group for two times of immersion Never the less, the best result as denture cleanser was obtained in Zamzam water which was showed the less value in surface roughness (µm).
