“…54 Although some reports have found that fluorine can enhance bacterial adhesion on the surface of biomaterials, 55,56 others have reported that fluorine shows antibacterial ability. 57,58 Our data indicate that the roughness of both TiO 2 nanotube surfaces was higher than that of the two control samples. We also found that the water contact angles on both TiO 2 nanotube surfaces, especially on the surface of the 80 nm TiO 2 nanotubes, were much lower than those of the two control groups, indicating that the TiO 2 nanotube surfaces had improved hydrophilic performance.…”

“…However, in another study, fluorine ions implanted on the PMMA surface did not change surface roughness. 37 Another approach to reduce the colonization of bacteria is via modification of surface free energy and chemistry. 37 Wettability decreased as contact angle increased.…”

Background: The current study objectives were to evaluate the influence of fluoridated glass fillers loading on the surface roughness, wettability, and adherence of candida and bacteria with and without saliva presence to a polymethylmethacrylate (PMMA) denture base material surface. Methods: Four concentrations of fluoridated glass fillers were added to PMMA: 1%, 2.5%, 5% and 10% by weight prepolymerization and 0% was the control. Discs of each concentration were fabricated (n = 5 for each variable). Surface roughness (R a ) was measured using atomic force microscopy (AFM). Wettability was assessed by measuring the contact angle of a sessile drop of water. Specimens were incubated with Candida albicans, or Streptococcus mutans with and without saliva coating. Adherence was presented as a percentage of the colonized surface area, counted using an optical microscope at x100 magnification. Results: The 10% group showed significantly greater roughness than the control and 1% groups; however, no significant differences in contact angle values were detected. The microbial adhesion was inversely proportional to the fluoridated glass fillers concentration where 10% concentration significantly decreased candidal and bacterial adhesion compared to others. Saliva coating significantly decreased microbial adhesion. Conclusions: It was concluded that fluoridated glass fillers could decrease microbial adhesion to acrylic denture base without adversely affecting surface properties.

ResumoNa medicina moderna, os biomateriais têm sido largamente utilizados como implantes. Dentre os biomateriais, o titânio de classe medicinal destaca-se pelo seu elevado grau de biocompatibilidade. Entretanto,órteses e próteses infectadas com microrganismos pós-implantadas requerem cirurgias e intervenções médicas que são dispendiosas e o tratamento pode levar meses. Para combater infecções associadas a implantes, a melhor estratégiaé prevenir que elas ocorram. Uma das estratégiasé a implantação deíons de prata no titânio. Neste trabalho,íons de prata foram implantados a baixas energias (4 keV) no titânio de uso medicinal com o objetivo de tornar a superfície do titânio bactericida e, assim, inibir a formação de biofilme. A implantação foi realizada em um equipamento do tipo Ion Plating. As amostras foram analisadas por espectrometria de Retroespalhamento de Rutherford (RBS), espectroscopia de emissãoótica por descarga luminescente (GD-OES) e difração de raios X (XRD). Os resultados obtidos mostram que a prata está implantada em profundidade de até 10 nm, corroborando com os dados da simulação realizada previamente. Além disso, a estratégia utilizada neste trabalho pode ser aplicada em escala industrial, devido ao tipo de equipamento utilizado para o tratamento da superfície. Palavras-chaveTitânio,Íons de Prata, Ion Plating, Implantação de Prata. Low Energy Ion Implanting of Silver Ion in Titanium AbstractIn modern medicine, biomaterials have been widely used as implants. Among biomaterials, titanium medical class is distinguished by its high degree of biocompatibility. However, orthoses and prostheses infected with post-implanted microorganisms require surgeries and medical interventions that are costly and treatment can take months. To combat infections associated with implants, the best strategy is to prevent them from occurring. One strategy is the silver ion implantation in titanium. In this work, silver ions were implanted at low energies (4 keV) in medical titanium with the goal to render bactericidal titanium surface and therefore, inhibit biofilm formation. The implantation was done using the Ion Plating equipment. After ion implantation, the samples were analyzed by Rutherford Backscattering Spectrometry, Glow-Discharge Optical Emission Spectroscopy and X-Ray Diffraction. The results show that the silver was implanted at depths up to 10 nm, corroborating simulation data. In addition, the strategy used in this work can be applied on an industrial scale due to the type of equipment used for the surface treatment. A prata, segundo a literatura, quando em baixa concentração em comparação com outrosíons de metais pesados, tem
