ABSTRACT
Dentures are commonly fabricated from heat-cured acrylic resin because of their aesthetics, affordability, and ease of repair, but their porous nature predisposes them to plaque accumulation, denture stomatitis, and halitosis, making effective cleaning essential. This study aimed to evaluate the effect of mechanical cleaning with an electric toothbrush, chemical cleaning with 0.5% sodium hypochlorite (NaOCl), and their combination on the surface roughness of heat-cured acrylic resin denture bases. A laboratory experimental study with a pre- and post-test control group design was conducted using rectangular acrylic resin specimens divided into three groups: electric brushing, 0.5% NaOCl immersion, and a combination of both. Surface roughness was measured using a TR 220 surface roughness tester before and after treatment, and data were analyzed using normality, homogeneity, paired t-test, and ANOVA with post hoc LSD tests. All groups showed a significant increase in surface roughness after cleaning (p < 0.05). The combined method produced the highest increase in roughness, followed by chemical cleaning with 0.5% NaOCl, whereas mechanical cleaning with an electric toothbrush alone resulted in the lowest increase. Mechanical, chemical, and combined cleaning methods all increased the surface roughness of heat-cured acrylic resin denture bases, with the combination of electric brushing and 0.5% NaOCl causing the greatest change, indicating the need to carefully select cleaning protocols to preserve denture surface integrity.
