| Soares et al. 2021 [7] in vitro | Microstructured annealed Ti G4/CoCrMo | 0.9% NaCl and BB at 225 ppm of F2 at pH 6 and pH 2 Naturally airy. 24 HOCP3, ZRA4.0.2 | (i) The corrosion resistance of the different couples decreased in the mouthwash solution. |
| Acid-treated Cp Ti G4/CoCrMo | (ii) As the solution became more acidic, an increase in galvanic current values was observed. |
| Ti UFG1 / CoCrMo |
| Barros, camila 2020 [21] in vitro | Ti6Al4V/NiCr | (i) 0.9% NaCl at 227 ppm of F-, 2270 ppm F− and 12300 ppm F− | (i) The corrosion resistance of Ti6Al4V decreases with increasing fluoride concentration. |
| (ii) pH 5, 5 and 4, 0 | (ii) This decrease in resistance is more important in an acidic |
| (iii) OCP | (iii) Environment fluorinated except ppm 227 of F− at pH 5.5. |
| (iv) 15 days |
| (v) 1 |
| Mellado-valero et al. 2018 [2] in vitro | Ti G2/Au | (i) ASF pH 6, 5 and ASF pH3 | (i) In the ASF pH 6.5. |
| Ti G2/NiCrTi | (ii) The galvanic corrosion resistance has decreased compared to the results obtained in AS. |
| Ti G2/CoCr | (ii) OCP, CP5 and ZRA. | (iii) In the ASF pH 3. |
| Ti G2/CoCr-c | (iii) 30 min for OCP and 4 hours CP | (iv) The NiCr/Ti alloy loses its passivity and actively dissolves. |
| Ti G2/Ti6Al4V | (iv) 0.28: CoCr-c and NiCrTi | (v) The TiG2/Ti6Al4V couple shows a huge increase in corrosion rates. |
| (v) 5: CoCr, Ti6Al4V, AuPd | (vi) The Au alloy showed the most noble electrochemical behavior among all the materials studied. |
| Anwar, E.M. et al. 2011 [11] in vitro | Cp Ti/CM6 (NiCr) | (i) AS pH of 7.5 | The addition of fluoride caused a significant decrease in the corrosion resistance of various couples, mainly those of Ti6Al4V. |
| Cp Ti/CC7 | (ii) NaF added to AS: three different concentrations were tested: |
| Ti 6Al4V/CM (NiCr) | (iii) 0, 01 M, M 0, 05 and 0.1 M |
| Ti6Al4V/CC | (iv) OCP and EIS8 |
