Assessment of Effect of Fluoride on Titanium Dental Implants

Background: Titanium has always been the material of choice for dental implants. The present study was conducted to assess effect of fluoride on titanium dental implants. Materials and Methods: Forty samples of pure titanium and Ti–6Al–4V were tested in an electrochemical cell. Results: Ecorr/V of titanium implant in artificial saliva was −0.42, and in artificial saliva, +0.25% NaF was −0.63. Ecorr/V of Ti–6Al–4V in artificial saliva was −0.56 and in artificial saliva +0.25% NaF was −0.60. Conclusion: There was significant effect of fluoride on titanium implants in terms of corrosion.
