Abstract

Abstract:

Objective

To evaluate antibacterial activity of the titanium samples after the surface structure had been altered by electric discharging using laboratory electrolytic method.

Methods

Titanium samples with identical specifications were placed in different electrolyte solutions and connected to the DC anode. The composition of the sample surface was modified by placing a cathode afterwards and discharging towards the samples. Then， the common oral bacteria were cultured and effects of the processed titanium samples on bacterial proliferation were examined.

Results

The titanium steel samples processed in various electrolyte solutions showed distinct antibacterial activities. The chloride-containing （Ti-Cl） samples demonstrated stronger antibacterial activity when compared to unprocessed samples.

Conclusion

The titanium steel samples processed in chloride-containing electrolytic solution under laboratory conditions demonstrated stronger antibacterial activity against common oral bacteria.
