Abstract (AI)
Both surface roughness and wettability may influence the adhesion properties of bacteria on biomaterials; in this context, the predominant factor is dependent on the bacterial species. Wettability was the predominant factor for S. epidermidis and surface texture for S. sanguinis. Zirconia did not show any lower bacterial colonization potential than titanium. Arithmetical mean roughness values R <sub>a</sub> (measured by stylus profilometer) are inadequate for describing surface roughness with regard to its potential influence on microbial adhesion.
Key Findings
1
Arithmetical mean roughness values Ra (measured by stylus profilometer) are inadequate for describing surface roughness with respect to its influence on microbial adhesion.
2
Surface texture was the predominant factor influencing initial adhesion of Streptococcus sanguinis on implant surfaces.
3
Wettability was the predominant factor influencing initial adhesion of Staphylococcus epidermidis on implant surfaces.
4
Zirconia did not exhibit lower bacterial colonization potential than titanium under the tested conditions.
