“…An aliquot of 300 μL of the precultured C. albicans was inoculated into 3 mL of TSBD. The number of C. albicans cells was approximately 1×10 6 to 1×10 7 CFU/mL. For the quantitative analysis of biofilms formed by S. mutans or C. albicans, ten samples of each alloy was immersed in the filtered pooled saliva overnight at 4ºC (Fig.…”

An analysis of the biofilms adhered to framework alloys using in vitro denture plaque models

The purpose of this study was to perform a quantitative and qualitative evaluation of the biofilms formed on framework alloys in vitro. The biofilms formed by unfiltered fresh human saliva or Streptococcus mutans and/or Candida albicans on commercially pure titanium and gold-copper-platinum demonstrated higher amounts than other alloy and resin samples. In contrast, the silverpalladium-copper-gold showed a significantly decreased level of biofilm formation. Although the adhesion level of Streptococcus mutans on cobalt-chromium was high, that of Candida albicans was less extensive. A T-RFLP analysis and qualitative PCR of the microbes in the biofilms were performed. In a cluster analysis of all T-RFLP profiles, the cobalt-chromium pattern was integrated into one cluster. On qualitative PCR, the existence of microorganisms related to caries, preriodontitis and aspiration pneumonia was observed. Our results showed that the biofilm formation on each framework alloy was different in terms of both the quantity and quality.

“…In the growing ranks of the elderly population, oral care is important for prevention not only of caries and periodontal disease, but also of systemic diseases such as aspiration pneumonia 1,2) . In particular, poor denture hygiene results in the accumulation of debris and bacterial plaque on the surface of prostheses, causing malodor and inflammatory changes to the adjacent mucosa 3) .…”

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

et al. 2009

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.

Background: The characteristics of tissue conditioners support microorganism development that can threaten the health of the dentures user.Purpose: The object of this study was to evaluate the effect on antimicrobial activity, roughness and wettability surface of a tissue conditioners material combined with the antimicrobial polymer poly (2-tert-butilaminoethyl) methacrylate (PTBAEMA). Materials and methods:Specimens of tissue conditioner (Coe Soft ® ) were divided into three groups, according to the concen tration of PTBAEMA incorporated (0, 10 and 25%). Antimicrobial activity was assessed by adherence assay of one of the microorganisms, Staphylococcus aureus, Streptococcus mutans and Candida albicans. Roughness measurements were made using a Mitutoyo SJ-400, and the mean arithmetic roughness values (Ra) obtained were used for the comparisons. The wettability properties were determined by contact angle measurements. Results:The group containing 25% of PTBAEMA inhibited totally the S. aureus and S. mutans biofilm formation. A significant reduc tion in the S. aureus (Kruskal-Wallis, p = 0,001) and S. mutans (Kruscal-Wallis, p = 0,001) count for 10% PTBAEMA group compared with respective control group. No significant difference was found for C. albicans among PTBAEMA groups and control group (ANOVA, p > 0,05). Incorporating 10 and 25% PTBAEMA increased surface roughness and decreased contact angles (ANOVA and Tukey's post hoc tests, α = 5%). Conclusion:Incorporating 10% PTBAEMA into tissue conditioner increases wettability and roughness of tissue conditioner surface; and decreases the adhesion of S. mutans and S. aureus on material surface, but did not exhibit antimicrobial effect against C. albicans. Significance:The PTBAEMA incorporated into tissue conditioner could prevent biofilm formation on elderly patient.

High correlation between the bacterial species in denture plaque and pharyngeal microflora

Abstract: Dentures should be considered an important reservoir of organisations which could colonise the pharynx, and the importance of controlling denture plaque for the prevention of aspiration pneumonia cannot be overemphasized.
