| Abstract | |
PURPOSE: The objective of this paper was to evaluate the biocompatibility of calcium phosphate cement in radius of rabbits. METHODS: For this experiment, calcium phosphate were implanted in the radius of 16 rabbits, divided in two groups (GI and GII), according to postoperative follow-up of 12 and 26 weeks, respectively. Reactions of these biomaterials on animal bone tissue were observed. X-ray, optical densitometry, optical microscopy and scanning electron microscopy analyses were performed. RESULTS: It was observed that calcium phosphate cement were partially resorbed during the 26-week follow-up, showing biocompatibility, with absence of inflammatory or other undesirable reactions due to the implants. CONCLUSIONS: Calcium phosphate-based cements did not cause inflammatory reactions when in contact with the osseous tissue, and were therefore biocompatible. Follow-up periods longer than 26 weeks are necessary to better evaluate the behavior of calcium phosphate-based cement. (AU) | |
