title: [The preliminary study of incorporating tetrapod-like zinc oxide whisker on the antibacterial activity of soft denture liners].
abstract: OBJECTIVE
  To research the effects of incorporating tetrapod-like zinc oxide whisker (T-ZnOw) of different proportions on the antibacterial activity of different kinds of soft denture liners.
  
  
  METHODS
  The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of T-ZnOw against Saccharomyces albicans (S. albicans) were examined by the broth dilution test. Add T-ZnOw 0%, 1%, 2%, 3% to Silagum soft denture liners and soft denture liners respectively. The antimicrobial rate of S. albicans was determined by the membrane covering method.
  
  
  RESULTS
  The MIC of T-ZnOw against S. albicans was 78 microg mL(-1) and the MBC was 156 microg mL(-1). Comparing 1%, 2%, 3% T-ZnOw group with control group, the results showed significant difference (P<0.05). And as the T-ZnOw antibacterial agent added ratio increased, antibacterial increased significantly.
  
  
  CONCLUSIONS
  The soft denture liners incorporating with 1%, 2%, 3% of T-ZnOw can improve antibacterial activity. Following the increased proportions of T-ZnOw, antibacterial rate was significantly increasing.
