“…Verran and Maryan [34] demonstrated that surface roughness may also facilitate Candida albicans retention in silicon prostheses. Taylor et al [35] verified that an increase in surface roughness (0.15-3.53 m) enhanced Candida albicans retention. Although the values of roughness of both materials are low (Ra < 0.5 m) the roughness of HAP is higher than that of acrylic (Fig.…”

The aim of this work was to compare the ability of strains of Candida albicans and Candida dubliniensis to adhere to acrylic and hydroxyapatite (HAP). In order to interpret the adhesion results, the surface properties of cells and materials were determined. Surface tension components (polar and apolar) and hydrophobicity were calculated through contact angle measurement and the elemental composition was determined by X-ray photoelectron spectroscopy (XPS). The results showed no significant differences in the number of adhered cells of both species to acrylic and hydroxyapatite. This was corroborated by the similarities in their surface properties and elemental composition. For both species, the adhesion to acrylic increased in the presence of artificial saliva due to the increase in the electron-donor capacity of this material. In the absence of artificial saliva, the number of adhered cells to HAP was greater than to acrylic, on account of the higher number of electron-donor groups of HAP. Hydrophobicity played a minor role in the adhesion process of both candidal species. Conversely, Lewis acid-base interactions seamed to govern this phenomenon.

“…The more hydrophilic and rougher, the better for bacterial adhesion. 10,73 There are at least two phases of bacterial attachment to distinguish: reversible (non-specific) and irreversible (specific). The reversible adhesion relies on the non specific physical and chemical characteristics of the bacteria, as well as on the biomaterial and surrounding joint fluid.…”

In spite of its incidence decreasing to 1% nowadays, prosthesis-related infection remains a research, diagnostic, therapeutic and cost-related problem. It can be defined as a presence of bacteria in the artificial joint space, which is significantly associated with evident laboratory and/or tissue markers, and clinical signs of running infection. We believe that the more precise understanding of pathogenesis, the more effective preventative and therapeutic measures, and the lower infection rate. The implants are colonized by airborne, skin-, and/ or surgeon-related bacteria during surgery despite being operated in closely respected operating regime. Some prosthetic characteristics are advantageous and may play important roles in the process of bacterial adherence. After successful attachment on the biomaterial surface bacteria multiply and physiologically transform into a "biofilm" community, making them much more resistant to antibiotic therapy and host immunity. Bacterial resistance is a complex phenomenon influenced by intrinsic and extrinsic factors, including the cell configuration in the biofilm community. So the cure of periprosthetic sepsis without removing of all foreign bodies and necrotic bone fragments is often ineffective. Acute hematogenous sepsis is suggestive of a distortion of a previously aseptic joint space by invasion of bacteria through the vessels.operative cultures in the group of 29 preoperatively "aseptic" cases. 57

“…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)
