Research Abstract

We developed a high functional apatite cement which have improved osteoconduction and release antibiotic continuously. Also, after we fabricated jaw osteomyelitis model using adult rabbit, we evaluated antibacterial effect on apatite cement containing antibiotic histologically. As a result, jaw osteomyelitis perfectly recovered by using apatite cement containing antibiotic. We concluded that apatite cement containing antibiotic was a good candidate for potential use as a DDS carrier that may be useful in jaw osteomyelitis treatment.
