The effects of Mg‐ion implantation and sandblasting on Porphyromonas gingivalis attachment

Abstract

Chemically modified surface increase the attachment of a major periodontopathic bacterium, P. gingivalis.

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

“…Microorganism colonization is initialized by the adhesion of pioneer species such as Streptococcus oralis , Streptococcus sanguinis, and Actinomyces naeslundii through interaction with the saliva pellicle 19 . The first colonizers promote a favorable environment for the attachment of late colonizers 20 including Porphyromonas gingivalis, a periodontal pathogen that adheres to matured biofilms 16 . Increased serum immunoglobulin G titers to P. gingivalis, Staphylococcus aureus, and Tannerella forsythia have been noted in individuals with failed implants 18 …”

“…4 It has been shown that the surface roughness of a Ti material affects bacterial affinity in the oral cavity. [12][13][14][15][16] Pereira da Silva et al, 12 in an in vitro study, noted increased bacterial cell attachment with the increased surface roughness of Ti material (surface roughness ranging from 0.17 to 3.17 mm). Similar results were reported by other studies.…”

Effect of bleaching agents and soft drink on titanium surface topography

“…8 In this current study the great surface roughness promoted by the bleaching agents on the Ti materials may be an important aspect for bacterial attachment to dental implants. It has already been proved that the implants' surface roughness plays a role on the microbial adhesion, [40][41][42] and consequently for the progression of peri-implantites and mucosites. [43][44][45] Additionally, a positive correlation between biofilm formation and implant failure has been noted.…”

Periodontal and peri‐implant diseases: identical or fraternal infections?

“…When failed implants in individuals with no history of smoking or diabetes were microscopically examined, surface roughness of the implant abutment and restoration were significant contributors to the microbial composition. Meanwhile, several in vitro investigations have revealed that P. gingivalis , Streptococcus pyogenes , S. mutans , Actinomyces naeslundii , Fusobacterium nucleatum , and Lactobacillus salivarius adhere significantly more effectively to roughened titanium, either acid‐etched or sand‐blasted surfaces (Grossner‐Schreiber et al ., ; Amoroso et al ., ; Frojd et al ., ; Almaguer‐Flores et al ., ; Kim et al ., ; Badihi Hauslich et al ., ). However, below a “threshold roughness” of < 0.2 μm, bacterial adhesion is not significantly affected (Bollen et al ., ).…”
