The antibacterial properties of Ca and Zn-containing coatings prepared with micro-arc oxidation

To prepare Ca and Zn-containing coatings using micro-arc oxidation on pure titanium surface and to investigate the coatings effect on S.mutans adhesion and morphology. Five groups including low Ca-containing (L-Ca), high Ca-containing (H-Ca), low Zn-containing (L-Zn), medium Zn-containing (M-Zn), hi...

Summary:To prepare Ca and Zn-containing coatings using micro-arc oxidation on pure titanium surface and to investigate the coatings effect on S.mutans adhesion and morphology. Five groups including low Ca-containing (L-Ca), high Ca-containing (H-Ca), low Zn-containing (L-Zn), medium Zn-containing (M-Zn), high Zn-containing (H-Zn) were prepared with micro-arc oxidation on titanium surface and machined commercial pure titanium (CP) was used as control group. Antibacterial properties of S.mutans on samples surface were appraised by the paster method and the change of bacteria was observed by SEM. SPSS 13.0 software package was used for all statistical analysis. The results showed that L-Ca and H-Ca groups had no significant difference in antibacterial property(P>0.05);Zn-containing groups had distinct antibacterial effect(P<0.01) compared with CP group,and there was significant difference between L-Zn and H-Zn group (P<0.05). Meanwhile,Zn-containing groups could affect adhesion and morphology of S.mutans by SEM. Zn-cont
