Resumo
Many authors have been trying to develop materials with antimicrobial activity and apply
them to different segments of Dentistry. Biocompatibility and significant antimicrobial
activity encourage the use of silver nanoparticles in biomaterials. The aim of this study was
to develop an experimental resin composite based on Bis-GMA and TEGDMA filled with
silver nanoparticles at a concentration of 100ppm in order to verify its antibacterial activity
againstStreptococcus mutans. Synthesized silver nanoparticles were characterized by UV-vis
(Visible Ultraviolet Spectroscopy), DLS (Dynamic Light Scattering), TEM (Transmission
Electron Microscopy), microbiological test, and XRD (X-ray Diffraction) techniques. Final
experimental composites were characterized by TGA (Thermogravimetric Analysis), FTIR
(Fourier Transform Infrared Spectroscopy), RAMAN (Raman Spectroscopy), and a direct
contact antibacterial test. Results showed nanoparticles with approximately 5 nm and
crystalline orientation. Silver nanoparticles interfere in the polymerization process affecting
the thermal stability of the material.
