“…This result may be explained by the fact that immersion in hypochlorite solutions did not cause significant changes on surface roughness of acrylic resins (4,5,(13)(14)(15). The present results indicate that this property was not altered by this solution even when employed in association to brushing.…”

“…The main chemical method of denture cleansing consists in immersing the prosthetic devices in solutions with solvent, detergent, antibacterial and antifungal actions (3). Among the proposed solutions, sodium hypochlorite is widely indicated due to its antimicrobial characteristics and has been suggested as an effective denture cleanser (4)(5)(6).…”

This study evaluated the abrasiveness of mechanical and combined methods of denture hygiene, by the analysis of mass loss and surface roughness. Acrylic resin specimens (Plexiglass) were brushed by a tooth brushing machine (Mavtec) with a soft brush (Tek) and water (control) or four dentifrices (Sorriso, Colgate, Polident and Corega) (Experimental groups) for 50 min, representing one year of brushing (mechanical method). After brushing, the specimens were immersed in 0.5% sodium hypochlorite simulating a daily cleaning of 20 min for one year (combined method). Distilled water (23 ºC) was employed as control. The mass loss (g) was analyzed by an analytical balance and the surface roughness (μm) by a rugosimeter. Data were subjected to ANOVA and Bonferroni test (α=0.05). Polident dentifrice showed lowest values of mass loss for both methods (mechanical: -0.0072±0.0017, combined:-0.011±0.002) and the combined method resulted in greater mass loss than the mechanical, except for Corega. For the surface roughness, after the mechanical method, the lowest values were registered for water (-0.007±0.016) and Polident (0.402±0.378); for the combined method, water (-0.063±0.013) showed the lowest values; there was no statistically significant difference between methods. It was concluded that Polident was the less abrasive dentifrice and the association between chemical and mechanical methods increased the mass loss but did not change the surface roughness of specimens.

The aim of this study was to investigate the influence of denture cleansing solutions on micro hardness of a heat-cure acrylic resin.Materials and Methods: Fifty specimens (15 mm × 15 mm × 3 mm) were prepared with a heat-cure acrylic resin. Specimens were randomly distributed into groups and immersed in the following solutions: 0.5% sodium hypochlorite (NaOCl), 1% NaOCl, alkaline peroxide tablet solution and, 0.2% chlorhexidine gluconate. The control group was immersed in distilled water. An immersion was detected 20-minute for all solutions. The microhardness value of each specimen was obtained using the microhardness testing machine recording the Vickers hardness number before the beginning of the immersion cycles and after completion of 720 immersion cycles and compared. Data were imported to SPSS 15.0 software and were analyzed by paired t-test and One-Way ANOVA and Tukey HSD test were used for comparison among groups (p< 0.05). Results:The results show that alkaline peroxide tablet solution caused the statistically significant reduction of the microhardness of the acrylic resin. Other solutions tested in this study did not cause a significant effect on the microhardness of the acrylic resin.Conclusions: It was concluded that immersion in distilled water, chlorhexidine gluconate, 0.5% NaOCl and, 1% NaOCl solutions, simulating 720 days of 20 min daily soaking did not cause clinically significant adverse effects on the microhardness of the heat-polymerized acrylic resin, except for the alkaline peroxide tablet solutions.

“…NaOCl solution that also used in the present study in the concentration of 5%, dissolves mucin, organic substances and shows antimicrobial activity by the action of hydroxyl ions and chloramination 20,29) . Several studies have reported satisfactory results for the antimicrobial activitiy of NaOCl solutions with different concentrations on denture base materials [30][31][32] . However, NaOCl has some disadvantages on denture base materials such as discoloration and an increase in surface roughness, depending on the concentration and immersion time 17,[33][34][35] .…”

This study investigated the effect of denture cleansers on the surface roughness and Candida albicans adherence of surface sealant agent coupled denture base resins. One hundred and twenty specimens were fabricated from 2 polymethyl methacrylate (PMMA) (Meliodent; Acron MC) and 1 polyamide (Deflex) denture base materials, coated with a sealant agent (Palaseal) and divided into 4 groups (n=10) according to overnight cleaning procedures: distilled water (control), 5% sodium hypochlorite (NaOCl) and two different sodium perborate (Corega; Rapident). The surface roughness values were measured with a profilometer before (Ra0) and after 90 days immersion in denture cleaners (Ra1). Specimens were incubated with Candida albicans suspension and Candida colonyforming units (CFU) (Cfu/mm) were counted. Significant differences were found, between the Ra0 and Ra1 values of 5% NaOCl applied Acron MC, Deflex and also Rapident applied Deflex groups (p<0.05). Denture cleaning procedures had no significant effects on the quantitiy of Candida albicans.
