Objective – The purpose of this study was evaluate in vivo the biocompatibility of the cements AH Plus, Acroseal and EndoREZ, after implantation in connective tissue of sixteen Wistar rats. Methods – The cements were put in the polyethilene tubs and implanted in specific areas in animal’s dorsal subcutaneous. The block of tissues was removed after 24 hours, 72 hours, 7 days and 21 days, histological processes was conducted and analyzed under optical microscopic observation. Results – The results indicated that all cements induced mild inflammatory reaction, that decreased with the experiment time. Conclusions – The Acroseal cement showed the best biological reaction, followed by AH Plus and EndoREZ.
