Resumen:
Implant infections can cause severe problems from malfunctioning to dangerous sepsis affecting the health of the patient. For many years, titanium has been the most common material used on dental implants due to their mechanical and biocompatibility properties. Recent studies suggest that amorphous carbon (a-C) films can be possible candidates for coating dental implants, improving some important features like biocompatibility and bone formation. In the oral cavity, the risk of an implant infection is high due to multiple species are capable to colonize this site and these biofilm infections can limit the use of these medical devices. The purpose of this study was to evaluate the influence of the surface chemistry, roughness, and culture media in the bacterial colonization process. To achieve this, a-C and Ti films were deposited on rough and smooth surfaces and cultured with different microorganisms belonging to the oral microbiota with mycoplasma medium (MM) or human saliva (HS).
