Abstract

PURPOSE:

To study the antibacterial activity of plasma sprayed silver-containing hydroxyapative(HA) coatings.

METHODS:

Silver-containing HA coatings were prepared on titanium substrated by vacuum plasma spraying (VPS). The samples were divided into 4 groups according to weight percent of the antimicrobial: group HA0 (0%),group HA1 (1%),group HA3 (3%) and group HA5 (5%). The antimicrobial properties against Streptococcus mutans were assayed with the pellicle-sticking method.

RESULTS:

When the weight percent of the silver was >3%, the silver-containing HA coatings exhibited significant anti-bacterial effects against Streptococcus mutans.

CONCLUSION:

The silver-containing HA coating has good inhibitory effect on Streptococcus mutans.
