Osteoblast adhesion on metallic titanium coated with anodic films was evaluated. The anodic oxidation treatment was carried out on commercially pure-titanium (cp-Ti) substrate under the following conditions: 1.0M H 2 SO 4 /150V and 1.0M Na 2 SO 4 /100V. Osteoblast cells were cultured onto the samples for 4 hours. The morphologies of both Ti anodic films and cells were observed by scanning electron microscopy (SEM). The oxide films are rough with porous structure. Statistical differences in

The oxide films prepared in H 2 SO 4 had greater contact angle, whereas there is no statistical significance between the values for the Ti anodic films produced in Na 2 SO 4 and the substrate surface. Despite the some differences in morphology, roughness and contact angle between the treated and nontreated samples, cell morphologies were similar on all surfaces after 4h of culture. Further, was not clearly observed a correlation between the surface characteristics with cell behavior.
