Effect of Denture Cleansers on Surface Roughness and Flexural Strength of High Impact Strength Acrylic Denture Base Materials: An In Vitro Study

Abstract

This study evaluated the effect of denture cleansers on surface roughness and flexural strength of high impact strength denture base material after successive immersions. A total of 50 specimens were fabricated and divided into 5 groups with 10 in each (n=10) based on the denture cleansing solution, Fittydent, Secure, Efferdent and Iodent. The specimens immersed in distilled water were considered as the control group. All the specimens were immersed in their respective cleansing solutions for 90 days. Surface roughness for all specimens before and after immersion was measured using surface profilometer and the flexural strength was measured after immersion for all specimens using universal testing machine. The collected data was analysed using one-way ANOVA with post hoc Tuckey test. All the specimens immersed in various denture cleansing solutions demonstrated more surface roughness compared to the specimens immersed in distilled water. A significant difference (p=0.0001) was observed among the groups after immersion for 90 days. The control group demonstrated more flexural strength compared to the specimens immersed in various disinfecting solutions for 90 days. However, no significant differences (p=0.9994) were observed in the flexural strength among the groups.
