“…The antibacterial effect of Ag has been reported in various therapies, including Agzeolite in tissue conditioners, 27 gargles containing Agzeolite, 28 and resins containing Ag. 29 In this study, the antibacterial effect of Ag was greater in Aa than in Sm (Figure 4). This was related to the different bacterial sensitivity against Ag, and a further study will be needed.…”

Objective: To develop a hard coating for stainless surfaces based on silver (Ag)-platinum (Pt) alloys. Materials and Methods: Ag-Pt alloys, which have high degree of biocompatibility, excellent resistance to sterilization conditions, and antibacterial properties to different bacteria, are associated with long-term antibacterial efficiency. Approximately 1.03-mm to 2.34-mm-thick coatings, as determined by scanning electron microscopy, were deposited on stainless surfaces by the simultaneous vaporization of both metals (Ag and Pt) in an inert argon atmosphere. The coating was done by physical vapor deposition. Microorganisms and eukaryotic culture cells were grown on these surfaces. Results: The coatings released sufficient Ag ions when immersed in phosphate-buffered saline and showed significant antimicrobial potency against Streptococcus mutans and Aggregatibacter actinomycetemcomitans strains. At the same time, human gingival fibroblast cells were not adversely affected. Conclusion: Ag-Pt coatings on load-bearing orthodontic bracket surfaces can provide suitable antimicrobial activity during active orthodontic treatment. (Angle Orthod. 2012;82:151-157.)

“…15,25,26 Hernández-Sierra et al 27 evaluated the sensitivity of Streptococcus mutans to nano particles of silver (25 nm), zinc oxide (125 nm) and gold (80 nm) and indicated the higher antibacterial properties of nano silver than nano zinc oxide and nanogold; they attributed this results to smaller particle size of nanosilver than nano zinc oxide particles. Concerns exist about the adverse effect of nanoparticle additives on the mechanical properties of composite resins; however, previous studies have reported silver compounds added in 10% concentration or greater to dental materials would significantly reduce compressive strength, elastic modulus and tensile strength.…”

Aim:The aim was to evaluate the antibacterial properties of composite resin containing nanosilver against Streptococcus mutans (SM) and Lactobacillus (L). Materials and methods:Nanosilver was added to Z250 composite at 0.5 and 1% by weight. In order to confirm the homogenous distribution of the nanoparticles in the composite resin, SEM-EDX analysis was performed on one sample in each group. Z250 composite without nanosilver was used as control. Direct contact test was used to test the antibacterial properties of nanoparticle-loaded composites: 0.001 ml of 0.5 Mc Farland suspension of MS and L was placed on composite disks, and incubated for 1 hour in 5 to 10% CO 2 incubator at 37ºC. Samples were placed in 0.5 ml of sterile BHI broth and incubated for 2 hours in CO 2 incubator. Afterwards, 0.001 ml liquid from each medium was distributed on blood agar plates and incubated for 48 hours in CO 2 incubator. The numbers of bacterial colonies were counted visually. Data were analyzed using Two-way ANOVA and Tukey HSD test. Significance level was set at 0.05. Results:Addition of nanosilver to composite resin had a significant effect on reduction of the number of SM and L colonies (p = 0.000). The antibacterial properties of composite resins are different depending on the concentration of nanosilver (p = 0.014). Tukey test indicated that increase in the concentration of nanosilver caused the increase in antibacterial properties of composite resin. Conclusion:Addition of silver nanoparticles to Z250 composite could significantly inhibit the growth of Streptococcus mutans and Lactobacillus on the surface of this composite.Clinical significance: The addition of nanosilver to Z250 composite could inhibit the growth of SM and L on the surface of the restoration and therefore prevent the occurrence of secondary caries.

“…Antimicrobial activity of dental materials is conventionally evaluated by using agar diffusion tests (Attin et al, 2001) or determining minimum inhibition concentrations (Yoshida et al, 1999), which are based on water solubility and diffusion rates of antimicrobial agents. Therefore, the use of these assays in determining dental and medical materials with antibacterial properties is questionable (Beyth et al, 2008).…”

Secondary dental caries are one of the major reasons for restoration replacements. Incorporating antimicrobial properties into dental materials would limit the initiation and progression of dental caries. In the current study, dental composites having 1%, 5%, and 10% (w/w) sodium pentaborate pentahydrate were prepared and analyzed for their mechanical properties, degree of monomer conversion (DC) rate, antibacterial effects against Streptococcus mutans, and biocompatibility with human dental pulp stem cells (hDPSCs). Incorporation of boron into the composites significantly decreased flexural strength and DC in a dose-dependent manner, but the value for 1% boron-containing composite still remained within acceptable levels. Compressive strength and diametral tensile strength were not found to be different from those of controls. Although no inhibition zone was detected in an agar-well diffusion assay for any materials tested, significant bacterial growth inhibition was obtained in a direct contact test for boron-containing composites. Immunocytochemical and lineage-specific gene expression analysis revealed that composites with boron content increased the osteogenic and odontogenic capacity of hDPSCs. Boron-containing dental composites showed promising results for future clinical applications, displaying nontoxic, osteogenic, and odontogenic-inducing characteristics with remarkable antibacterial activity against S. mutans, and are hence potentially able to prevent secondary caries.
