Scanning electron microscopy and microbiological approaches for the evaluation of salivary microorganisms behaviour on anatase titanium surfaces: In vitro study

Implantology research framed the implant surface as a key element for a good and sustainable osseointegration of an implant fixture. The aim of this study was to analyze the antibacterial properties of anatase-coated titanium healing screws through microbiological and scanning electron microscopy. The comparison of the bacterial colonies growth between the anatase-coated titanium healing screws and non-coated titanium healing screws showed comparable antibacterial properties, without significant statistical differences. The scanning electron microscopy observations confirmed the microbiological study. These data, also considering previous reports on the positive effects on osteoblasts genetic expressions, might suggest a use of the anatase-coated titanium healing screws to preserve the tissues surrounding implants from microbial attacks.
