Attachment of Porphyromonas gingivalis to Corroded Commercially Pure Titanium and Titanium‐Aluminum‐Vanadium Alloy

Abstract

A higher degree of corrosion on the titanium surface may promote increased bacterial attachment by oral pathogens.

Biofilm formation on polyetheretherketone and titanium surfaces

“…This may be related to the bacterial surface properties and sensitivity to Al or V components in the alloy. Barão et al (2014), observed higher attachment of Porphyromonas gingivalis to cp-Ti than Ti6Al4V. They suggest that the reduced attachment of P. gingivalis on Ti6Al4V could be explained by the antimicrobial effect of vanadium, as reported by Tousley, Wren, Towler, and Mellott (2012).…”

Increased Levels of Dissolved Titanium Are Associated With Peri‐Implantitis – A Cross‐Sectional Study

“…Irrespective of the etiologic factor for initiation of titanium corrosion, the resulting corroded surfaces of dental implants may offer amenable niches for colonization by bacteria. Porphyromonas gingivalis has shown increased attachment to corroded titanium disks compared with non‐corroded titanium disks, indicating that a corroded surface may promote increased bacterial colonization 13 . In addition, lipopolysaccharides from Gram‐negative bacterial cell walls have demonstrated a high affinity to titanium, while also promoting dissolution of the TiO 2 layer in pH 4.0 to 7.0 which is found in the oral environment 7 .…”

Bond strength and interactions of machined titanium-based alloy with dental cements

“…Once set, the cylinder pairs were incubated in a water bath at 37 C for 7 days. The cemented cylinders for each test cement (n=12) were subjected to a shear bond test, with the testing setup reported in a previous study, 16 and the peak shear force was recorded. The debonded surfaces of the Ti alloy disks were examined under a light microscope (BX51 TRF; Olympus Corp) at ×10 magnification to record and compare the mode of failure.…”

“…Color change has been associated with corrosion of the titanium alloy, 14 which may account for the higher than expected bond strength values. Although this may be of benefit mechanically, 15 the corrosion effects have been linked to implant failure 16 and an increase in pathogenic microbial adherence to the alloy. 17 Also, fluorinated acidic dental cements increase titanium corrosion susceptibility.…”
