“…Although some studies have suggested that the adhesion ability of yeasts to polymeric surfaces is modulated by hydrophobic forces, others found no correlation between hydrophobicity and Candida adhesion (8)(9)(10). It has also been reported that an increase in surface roughness enhances C. albicans retention (11)(12)(13)(14) as it increases the surface area and/or shear forces (5), thus allowing easier microbial attachment and difficult detachment even when the prosthesis has been cleaned with antimicrobial agents (10). However, most of these studies focused on the adherence of C. albicans to rough denture surfaces (3,(11)(12)(13), but failed to investigate the efficiency of antimicrobial agents in removing yeasts from these surfaces.…”

Abstract:The aim of the present study was to compare the effects of some disinfectants, including ethanol extract of propolis (EEP), on the adhesion of Candida albicans to denture base resins. Seventy-two acrylic resin samples were prepared, half of which was polished and the other half was roughened. C. albicans strain ATCC 10231 was incubated on Sabouraud dextrose agar (SDA) at 37°C for 48 h. The adhesion period was completed by keeping the cells in this suspension for 90 min at 37°C. Specimens were then immersed in the following solutions: 1%, 2%, and 5% sodium hypochlorite; 4% chlorhexidine gluconate; and 10% EEP. Quantification of the antifungal activity of the chemical solutions was performed using the colorimetric MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assay test. One-way ANOVA and post-hoc Tukey tests were performed to evaluate the effectiveness of chemical agents. Polished and roughened surfaces were compared using independent sample t-test. The mean surface roughness value was 0.35 (±0.04) µm for the polished group and 1.2 (±0.2) µm for the roughened group. The contact angles of both surfaces showed statistically significant difference, and 10% EEP solution exhibited significantly less removal of adherent viable C. albicans cells in both groups. All forms of sodium hypochlorite solutions yielded higher efficiency than 4% chlorhexidine gluconate and EEP solutions (P < 0.05). (J Oral Sci 58, 431-437, 2016)

“…As most denture materials are porous acrylic resins, water is easily absorbed, so that when denture hygiene is neglected, the denture becomes stained and unpleasant-smelling, with resulting bad breath 8,9) . While the denture is being worn, bacteria easily proliferate between the mucous membrane and the denture 10) , and the denture plaque containing bacteria adheres more easily to a denture surface that is scratched due to an incorrect cleaning method 11) . We use Raverrack D (Sundental, Osaka, Japan) as the denture cleaner in our hospital.…”

Bactericidal efficacy of glycine-type amphoteric surfactant as a denture cleaner and its influence on properties of denture base resins

The bactericidal efficacy of 1.00-4.50% glycine-type amphoteric surfactant (Gly) was evaluated by measuring its microorganism removal rate in denture plaque. Physical and mechanical properties such as surface roughness, color difference, and bending strength of two different denture base resins were determined before and after cleaning in Gly solutions, a commercial denture cleaner, and tap water. The microorganism removal rates of all the Gly solutions were higher than those of a commercial enzymatic denture cleaner (Polident) (p>0.05). The removal rate of Candida spp. by Polident was not significantly different from the removal rate using water. Changes in the surface roughness and color difference among the specimens were slight. There were no significant differences in the bending strengths of the two resins for all concentrations of Gly solution (p>0.05). These results suggested that glycine-type amphoteric surfactant solution may be effective as a denture cleaner in conjunction with an ultrasonic cleaning device.

“…As the adherence of Candida albicans to denture surfaces is now recognized as an important phase in its colonization and pathogenesis, inhibiting the early adherence process would be a significant measure in the prevention of stomatitis 3) . The adherence of Candida albicans is influenced by many factors, such as surface roughness, salivary pellicle, surface free energy, and the type of denture base material [4][5][6][7] . Some researchers found that an increase in surface roughness promoted fungal adhesion 5,6,8) .…”

Atmospheric-pressure cold plasma was applied to process the surface of heat-polymerized acrylic resin. Changes to the physical properties and early adherence of Candida albicans were investigated. Alternating current cold plasma with Ar/O2 as working gas was used. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) were employed to study the possible mechanism. Experimental results showed that after plasma treatment, the contact angle of acrylic resin significantly decreased. There were no significant differences in roughness, flexural strength and elasticity modulus, but microhardness was significant improved in the treated group. More importantly, the early adherence of Candida albicans on the surface was reduced after plasma treatment. Cold plasma seemed to be a promising and convenient strategy of preventing the early adherence of Candida albicans on acrylic resins, which would greatly benefit potential dental applications.
