However, the oxide layer issensitive to corrosive ions such as fluoride (F) and hydrogen peroxide(H2O2) which are normally found in human mouth. Commercially produced toothpastes, mount rinses and cariostatic gels contain between0.1% and 1% content F concentration. Furthermore, H2O2 can be secreted during inflammatory reactions by bacteria in oral environment.The corrosion of dental implants and components can cause failure ofdental implant treatment. The aim of this study was to analyse the effects of different F and H2O2 concentrations on different treated Ti alloy(Ti6Al4V) in surfaces. Material and Methods: The effects of different F (0.5%, 2.5%) and H2O2 (0.1%, 10%) concentrations on differenttreated Ti6Al4V surfaces [electro-polished, roughed, fine-roughed andsodium titanate-treated (NaTi)] were analysed. Scanning electron microscopy and inductively coupled plasma with optical emission spectrometer provided quantitative bulk elemental composition for Tisamples. Results: Median corrosion values of Ti (mg/L) and V (mg/L)corrosion levels in 10% H2O2 and 2.5% F solutions were significantlyhigher than 0.1% H2O4, 0.5% F and control solutions. Median Ti corrosion values observed in electro-polished, roughed and fine-roughedgroups were statistically higher than NaTi treated surfaces. Conclusion: This study shows that low ion release on NaTi surfaces causesthe least amount of corrosion. Consequently, NaTi coating should beconsidered as the best alternative for protecting Ti surfaces from corrosion.eninfo:eu-repo/semantics/openAccessDiş HekimliğiArticle271899710.5336/dentalsci.2020-77759454300
