ABSTRACT
 Objective: Titanium (Ti) and Ti alloys are suitable options as implant material because they are biocompatible and form a corrosion protective titanium oxide layer. However, the oxide layer is sensitive 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 between 0.1% 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 of dental 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 different treated Ti6Al4V surfaces [electro-polished, roughed, fine-roughed and sodium titanate-treated (NaTi)] were analysed. Scanning electron microscopy and inductively coupled plasma with optical emission spectrometer provided quantitative bulk elemental composition for Ti samples. Results: Median corrosion values of Ti (mg/L) and V (mg/L) corrosion levels in 10% H2O2 and 2.5% F solutions were significantly higher than 0.1% H2O4, 0.5% F and control solutions. Median Ti corrosion values observed in electro-polished, roughed and fine-roughed groups were statistically higher than NaTi treated surfaces. Conclusion: This study shows that low ion release on NaTi surfaces causes the least amount of corrosion. Consequently, NaTi coating should be considered as the best alternative for protecting Ti surfaces from corrosion.

ÖZET
 Amaç: Titanyum (Ti) ve Ti alaşımları biyouyumlu olmaları ve korozyon koruyucu titanyum oksit tabakası oluşturmaları sebebi ile implant malzemesi olarak uygun seçeneklerdir. Bununla birlikte, oksit tabakası diş hekimliğinde kullanılan koruyucu solüsyonların aşırı kullanımına ve florür (F) ve hidrojenperoksit (H2O2) gibi insan ağzında bulunabilen aşındırıcı iyonlara karşı duyarlıdır. Diş macunları ve ağız gargaraları %0,1-%1 içerik F konsantrasyonu içerir. Ayrıca H2O2 oral alanda bakteri tarafından inflamatuar reaksiyonlar sırasında salgılanabilir. Dental Ti implantların ve bileşenlerinin korozyonu dental implant tedavisinin başarısız olmasına neden olabilir. Bu araştırmanın amacı, farklı F ve H2O2 konsantrasyonlarının farklı muamele edilmiş Ti yüzeyleri üzerindeki etkilerini analiz etmektir. Gereç ve Yöntemler: Farklı F (%0,5, %2,5) ve H2O2 (%0,1, %10) konsantrasyonlarının, farklı şekillerde hazırlanmış Ti yüzeyleri [elektroliz ile parlatılmış, kumlanmış, ince kumlanmış, sodyum titanat (NaTi) ile kaplanmış] üzerindeki etkileri, taramalı elektron mikroskobu ve endüktif olarak eşitlenmiş plazma optik emisyon spektrometresi ile analiz edilmiştir. Bulgular: %10 H2O2 ve %2,5 F çözeltilerinde Ti (mg/L)] ve V (mg/L) elementlerinin ortalama korozyon değerleri, %0,1 H204 ve %0,5 F ve kontrol çözeltilerinden anlamlı derecede yüksek bulunmuştur. Ayrıca elektroliz ile parlatılmış, kumlanmış ve ince kumlanmış gruplarda gözlemlenen ortalama Ti korozyon değerleri, NaTi ile işlenmiş yüzeylerden istatistiksel olarak anlamlı derecede daha yüksek bulunmuştur. Sonuç: Elde edilen verilere göre düşük iyon salınımı göstermesi sebebi ile NaTi yüzey kaplaması, Ti yüzeyleri korozyondan korumak için en iyi alternatif olabilir.
