Enhancing the antibacterial properties of implant surfaces is a promising way to reduce the occurrence of inflammations. In this in vitro study, the antibacterial potential of two nanocomposite surfaces were investigated, as possible new materials for implantology.The structural and photocatalytic properties of the TiO2 and Ag-TiO2 (with 0.001 wt% plasmonic Ag content) photocatalyst containing polymer based composite layers were also studied and compared to the unmodified standard sandblasted and acid etched Ti discs (control). The presence of visible light induced reactive oxygen species was also verified and quantified by luminol based chemiluminescence (CL) probe method. The discs with adhered Streptococcus mitis were illuminated for 5, 10 and 15 min. The antibacterial effect was determined by the metabolic activities of the adhered and proliferated bacterial cells and protein assay at each time point.The Ag-TiO2 containing surfaces with obvious photocatalytic activity eliminated the highest amount of the metabolically active bacteria, compared to the control discs in the dark, after 15 min illumination.The plasmonic Ag-enhanced and illuminated surface exhibits significantly better antibacterial activity under harmless visible light irradiation, than the control Ti or TiO2 containing copolymer. The studied surface modifications could be promising for further, more complex investigations associated with dental research on infection prevention in connection with oral implantation.}, keywords = {NANOPARTICLES; ANTIMICROBIAL ACTIVITY; Photocatalysis; Peri-implantitis; Pioneer colonizer}, year = {2020}, eissn = {1879-1506}, orcid-numbers = {Venkei, Annamária/0000-0002-1893-7526; Eördegh, Gabriella/0000-0002-3707-3583; Janovák, László/0000-0002-2066-319X; Zsoldiné Urbán, Edit/0000-0002-9602-7552} } @article{MTMT:31240664, title = {A simplified in vitro model for investigation of the antimicrobial efficacy of various antiseptic agents to prevent peri-implantitis}, url = {https://m2.mtmt.hu/api/publication/31240664}, author = {Venkei, Annamária and Eördegh, Gabriella and Turzó, Kinga Mónika and Zsoldiné Urbán, Edit and Ungvári, Krisztina}, doi = {10.1556/030.2020.01080}, journal-iso = {ACTA MICROBIOL IMMUNOL HUNG}, journal = {ACTA MICROBIOLOGICA ET IMMUNOLOGICA HUNGARICA}, volume = {67}, unique-id = {31240664}, issn = {1217-8950}, abstract = {The biofilm formation by oral bacteria on the implant surface is one of the most remarkable factors of peri-implant infections, which may eventually lead to bone resorption and loss of the dental implant. Therefore, the elimination of biofilm is an essential step for the successful therapy of implant-related infections. In this work we created a basic in vitro model to evaluate the antibacterial effect of three widely used antiseptics.Commercially pure (CP4) titanium sample discs with sand blasted, acid etched, and polished surface were used. The discs were incubated with mono-cultures of Streptococcus mitis and Streptococcus salivarius. The adhered bacterial biofilms were treated with different antiseptics: chlorhexidine-digluconate (CHX), povidone-iodine (PI), and chlorine dioxide (CD) for 5 min and the control discs with ultrapure water. The antibacterial effect of the antiseptics was tested by colorimetric assay.According to the results, the PI and the CD were statistically the most effective in the elimination of the two test bacteria on both titanium surfaces after 5 min treatment time. The CD showed significant effect only against S. salivarius.Based on our results we conclude that PI and CD may be promising antibacterial agents to disinfecting the peri-implant site in the dental practice.}, keywords = {TITANIUM; Peri-implantitis; Streptococcus salivarius; Antimicrobial agents; Streptococcus mitis}, year = {2020}, eissn = {1588-2640}, pages = {127-132}, orcid-numbers = {Venkei, Annamária/0000-0002-1893-7526; Eördegh, Gabriella/0000-0002-3707-3583; Zsoldiné Urbán, Edit/0000-0002-9602-7552} } @{MTMT:3419127, title = {In vitro modellek tesztelése felületmódosított titán felszínek antibakteriális hatásának vizsgálatán keresztül}, url = {https://m2.mtmt.hu/api/publication/3419127}, author = {Venkei, Annamária and Turzó, Kinga Mónika and Zsoldiné Urbán, Edit and Ungvári, Krisztina}, booktitle = {Magyar Arc-, Állcsont- és Szájsebészeti Társaság XXII.
