Evaluation of a biofilm formation by Desulfovibrio fairfieldensis on titanium implants

Abstract

Desulfovibrio fairfieldensis is one of the most relevant sulphate-reducing bacteria of the human oral cavity suspected to be involved in peri-implantitis and implant corrosion. This study demonstrates for the first time that Des. fairfieldensis is able to initiate the formation of a biofilm-like structure on the microstructured titanium coupons used in dental implants and that it improves its resistance to antibiotic treatment. It gives new insight to understand the capacity of this opportunistic pathogen to colonize implant surfaces and to resist to biocide treatments.

Bacterial adhesion and biofilm formation on yttria-stabilized, tetragonal zirconia and titanium oral implant materials with low surface roughness - an in situ study

“…In future studies, to evaluate the effects of ginigival fluid on microbial adhesion, pretreatment of the implant materials with fetal bovine serum, which mimics gingival fluid (Jorand et al, 2015), should be conducted prior to the main microbiological assays.…”

A comprehensive review of the local risk-factors associated with the etiology of peri-implant diseases

“…One of such features is poor oral hygiene maintenance. The dental plaque is the core etiological factor that causes the development of oral biofilm around the teeth and dental implant surfaces [30][31][32][33][34] . In the study by Serino and Ström 35 , most of the implants with a diagnosis of peri-implantitis were associated with no accessibility and/or capability for appropriate oral hygiene measures.…”

Initial stage of the biofilm formation on the NiTi and Ti6Al4V surface by the sulphur-oxidizing bacteria and sulphate-reducing bacteria

“…The improvement of safety and efficiency of the metal alloys usage in certain specific environments requires taking into account numerous factors of abiotic and biotic origin [ 1 – 3 , 6 , 7 ]. Amongst them, the susceptibility to the fouling of the implants made of Ti-containing alloys due to the adhesion of microorganisms and the biofilm formation is very significant [ 8 – 13 ], especially in the context of an inflammatory state induced by implants contaminated by bacteria [ 10 ]. The implants’ corrosion influenced by bacteria is also an important problem [ 10 , 12 , 13 ]—although titanium alloys are characterized by high corrosion resistance in natural and most industrial environments [ 1 – 3 ].…”
