Notes:
The effect of Si doping on the bioactivity and characteristics of hydroxyapatite/TiO2 compositefilms was investigated. Pure titanium plates were treated to form Ca, P and Si enriched titania-based filmsby using micro-arc oxidation (MAO). Then, some specimens were undergone a further hydrothermaltreatment to produce a thin outermost layer of hydroxyapatite (HA). Experiments revealed that that thefilm, which was about 10μm thick, was composed of amorphous silicon dioxide, amorphous calciumphosphate, rutile and anatase. The film was porous and uneven, with the pore size of 1-4μm. No obviouscracks exist on the surface. In order to investigate the cytocompatibility of the films, periodontal ligament(PDL) cells were seeded onto the surface of the films. It was concluded that the Si ion did not influencethe characters of MAO film but Si enriched hydroxyapatite/ TiO2 composite coatings exhibited an effecton cell attachment
