“…These antibacterial compounds include the use of benzalkonium chloride, quaternary ammonium salts, and synthesized nanoparticles from silver, zinc oxide, cooper oxide, titanium dioxide, and others ( 9 - 13 ). On the other hand, the addition of antibacterial agents to orthodontics resins seems to decrease the bond strength to enamel, this effect is correlated to the concentration of the antibacterial agent ( 14 ).…”

Background To evaluate the antibacterial property of a modified orthodontic resin with different concentrations of silver-nanoparticles (AgNPs), and quantify its preventive effect on the formation of white spot lesions (WSLs). Material and Methods An orthodontic resin (Transbond XT) was modified with four concentrations of AgNPs (1%, 0.5%, 0.1%, and 0.05%), the orthodontic resin without AgNPs was used as control. Polymerized resin discs (n=80) were submitted to Agar diffusion test on Petri dishes inoculated with Streptococcus mutans and Lactobacillus acidophilus . In addition, resin discs of each group (n=40) were placed in 96-well plates with bacterial suspensions to evaluate the colony-forming-units (CFU). For the WSLs prevention test, brackets were bonded with the experimental orthodontic resins on 45 premolars (n=5), and were subjected to a microbiological caries induction method for 9 days. Photographs were taken before and after the test, and the images were evaluated with the Image J software to calculate the area of WSLs. The data were analyzed using ANOVA and Tukey-HSD test, Student´s t-test and Kruskal-Wallis test (α=0.05). Results The 0.5% and 1% AgNPs modified resin inhibit the growth of S. mutans and L. acidophilus . All the modified resins showed significantly less CFU, when compared to the control ( p <0.05). 1% AgNPs resin promote the higher prevention of WSLs formation. There was no significant difference between the control group and the 0.1% and 0.05% groups. Conclusions 0.5% and 1% of AgNPs modified orthodontic resin exhibit an important antibacterial activity against S. mutans and L. acidophilus , and prevent the formation of WSLs. Key words: White spot lesions, antibacterial, orthodontics, adhesive, Silver-nanoparticles.

“…Con el objetivo de eliminar el factor de colaboración del paciente, diversos reportes han propuesto la incorporación de agentes antibacterianos en los cementos ortodónticos como sales de amonio cuaternario, cloruro de benzalconio, nanopartículas sintetizadas a partir de metales o productos naturales (Reddy et al, 2016;Sodagar et al, 2017;Torres-Garcia et al, 2019;Yassaei et al, 2020). Todas estas estrategias han sido efectivas en controlar e inhibir el crecimiento de bacterias asociadas con la formación de las LMB.…”
