Objective To investigate the corrosion behavior of titanium in artificial saliva with albumen. Methods Samples of titanium were prepared, and were treated with Fusayama artificial saliva (control group, n=3), Fusayama artificial saliva added with 0.01% bovine serum albumin (experiment group 1, n=3) and Fusayama artificial saliva added with 0.05% bovine serum albumin (experiment group 2, n=3) respectively. Tafel curve tests were performed with electrochemical methods, and the change of corrosion behavior of titanium in artificial saliva with albumen was analysed. Results Tafel curve tests indicated that the values of self-corrosion potential of titanium samples were (－349.1±19.6）mV,（－325.2±18.8） mV and (－218.2±12.5) mV respectively, and the values of self-corrosion current density of titanium samples were (3.57±0.52)×10^-2 A/cm², (3.52±0.29) ×10^-2 A/cm² and (3.64±0.70)×10^-2 A/cm² respectively in control group, experiment group 1 and experiment group 2. Statistical analysis revealed that there was no significant difference in the values of self-corrosion current density among three groups (P>005), and the value of self-corrosion potential in experiment group 2 was significantly higher than that in control group (P<0.05). Conclusion Artificial saliva with albumen may influence the corrosion behavior of titanium, which may be related to the change of self-corrosion potential of titanium.
