| ABSTRACTBackground: recently the ordinary Portland cement (OPC) has been analyzed and compared physically, chemicallyand biologically to mineral trioxide aggregate MTA and because of the similarity between OPC and MTA, So thePossibility of using Portland cement as a less expensive alternative to MTA in dental practice should be considered. Inview of this, the Present study is to evaluate the biological response of the jaw bone to intraosseous ordinary Portlandcement (OPC) implantation.Materials and Methods: fifteen local breed adult male rabbits divided into three groups of five rabbits, each rabbithas receive two intrabony defects in the mandible bone, one filled with white ordinary Portland cement (WOPC), theother left empty as a control The histological sections obtained after 1, 4 and 8 weeks postoperatively. Thehistomorphometric analysis including counting of bone cells (osteoblasts & osteoclasts) ,inflammatory cell andobservation of the degree of inflammation and the type of bone reaction to OPC material.Results there was no significant difference in inflammatory response between OPC group and control group at allperiod of time, , there was significant increase of osteoblasts number at one and four weeks interval of OPC groupwhen compare with the control groups but at eight week there were no significant difference of osteoblastsnumber between them, control group showed highly significant increase of osteoclasts number at four and eightweeks interval when compare to OPC groups. Most of OPC group and in all period of time showed bone depositionin direct contact with ordinary Portland cement (Type I bone reaction).Conclusions: As a result we can conclude that the OPC material show high degree of biocompatibility, induce bonehealing and act as bioactive material.Key words : Portland cement,intaosseos inplantation, bone biomaterial.
