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

Purpose: 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.

Methods: 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.
