Tricalcium phosphate (TCP) synthetized by high temperature solid state reaction at 1400°C and three derived calcium phosphate cements (CPCs) prepared at liquid to powder (L/P) ratios of 0.33, 0.44 and 0.55 ml/g, respectively, were physicochemically characterized. Calcium deficient hydroxyapatite crystals were identified by scanning electron microscopy on CPC, and differences in crystal sizes were observed at different L/P ratios. Also, the biofilm thickness of two Staphylococcus Aureus (S.aureus) strains grown for 24 hours on the three CPC are reported. A dependence of the biofilm thickness with the specific surface area (SSA) of CPC was identified. They are directly proportional for non-extracellular polysaccharide substances (EPS) producing S.aureus and inversely proportional for EPS producing S.aureus. Non-proportional behavior between the SSA and mechanical strength of the CPC was observed as L/P ratio increases.
