“…The mechanism by which plaque adheres to and forms on the surface of teeth and restoration materials has been extensively studied (3)(4)(5). Saliva-derived pellicles immediately form on the surfaces of thoroughly cleaned teeth and attract bacteria through chemical or electrostatic interactions or by antigens on the surfaces of bacterial cells (6).…”

We used a polymicrobial (PM) biofilm model to examine associations of bacterial adhesiveness with surface characteristics of various dental materials. Four types of dental materials (apatite pellet, zirconia, ceramic, and composite resin) with rough and mirror surfaces were used. Surface roughness, surface free energy, zeta potential, and colony-forming units (CFUs) of the biofilm formations were measured. Biofilms were cultured for 24 h under anaerobic conditions, plated onto blood agar medium, and anaerobically cultured for 4 days. After culturing, CFU per mm 2 was calculated, and samples were observed under a scanning electron microscope. Means and standard deviations of the experimental data were estimated, and one-way ANOVA and Tukey multiple comparison assays were performed. Pearson correlation coefficients were obtained for the CFU and surface characteristics. Surface roughness and surface free energy appeared to affect generation of PM biofilms on oral materials, and zeta potential was involved in generation of PM biofilms on mirrorground oral materials.

“…These findings are important because a change in the roughness of modified resin could increase the biofilm accumulation. In accordance with this, several studies have shown that a rougher surface favors the biofilm growth on restorative materials (18)(19)(20). In contrast, an experimental composite adhesive containing silver nanoparticles that also presented bactericidal property showed rougher surface than conventional adhesive (15).…”

The objectives of this study were to evaluate physical properties and antibacterial activity of a light-activated composite modified with silver nanoparticles. Discs were produced with unmodified resin (control group -CG) and modified resin with silver nanoparticles at two concentrations, 0.3% wt (MR03) and 0.6% wt (MR06). Streptococcus mutans and Lactobacillus acidophilus biofilms were induced in vitro by incubation of discs in a 20% sucrose medium, followed by sonication and counting of viable cells after 1, 4 and 7 days (n=9). The arithmetic roughness of all three groups was evaluated by atomic force microscopy (n=9). Compression assay was conducted in all groups to measure the compressive strength at failure and elasticity modulus (n=5). Data were subjected to ANOVA and Tukey's tests (α=0.05%). At all three time points the number of viable cells was statistically lower for MR03 and MR06 compared with CG, for both specimens. MR03 and MR06 showed no significant differences. Microscopic analysis demonstrated no significant differences for roughness among the three groups (p>0.05). The MR03 was stronger to compression than CG, and MR06 was statistically lower than CG and MR03. It was concluded that the MR03 were less conducive to biofilm growth, without compromising the strength in compression and surface roughness.

“…The surface characteristics of the solid substratum and the adhering bacteria can affect the adherence process 20 . Aykent et al 21 observed a positive correlation between surface roughness and S. mutans adhesion. Several studies shown the oral bacterial adherence on rough surfaces of dental implant biomaterials 22,23 .…”

The loss of a metallic implant can be caused by the presence of sessile bacteria, biofilm formation and infection. The aim of this study was to evaluate bacterial adhesion on pure titanium used in dentistry. The experiment was conducted in a liquid culture sésseis isoladas e agrupadas, compatíveis com a estrutura morfológica de cocos aderidos nas superfícies lisa e rugosa.A contagem das células viáveis foi semelhante para superfície lisa e rugosa, a nível 0,05 as médias não mostraram diferenças significantes. Comparando-se as superfícies lisa e rugosa (modificada por aplicação de feixe de laser de alta intensidade Nd:YAG) não foi observada redução significante no número de bactérias aderidas à superfície rugosa, o que sugere que a modificação física cria uma superfície favorável à aderência de S. mutans, a qual pode ser pré-requisito para o desenvolvimento de biofilmes em implantes dentários cirúrgicos e à patogênese da infecção.
