<![CDATA[Introduction: Alveolar bone is the most affected of the periodontal diseases. Bone grafts such as autograft, allograft, xenograft and, alloplastic often are used, but they have limitations. So, the bone graft is still a major problem that continues to inspire the design of new bone materials. The purpose of this article is to review the clinical and biologic function, advantages, and disadvantages of dentin as an autograft and allograft bone in periodontal therapy. Review: Autograft is still the gold standard in bone augmentation because of its excellent osteoinductivity and osteoconductivity. Bone and dentin are mineralized tissues that have almost similar chemical compositions. Dentin matrix obtained from a tooth has to be demineralized before using it as a bone graft material. Dentin consists of 18% collagen, 2% noncollagenous proteins, 70% hydroxyapatite, and 10% body fluid. Matrix is a repository for growth factors, such as Bone Morphogenetic Proteins (BMP), Transforming Growth Factor-β (TGF-β), Insulin-like Growth Factor (IGF), and Basic Fibroblast Growth Factor (bFGF). Demineralized Dentin Matrix (DDM) is highly biocompatible and can support cell growth and proliferation, enhances the bone remodeling capabilities and autograft leads to the absence of antigenicity. Autograft DDM was further suggested to be an ideal scaffold for stem cells and bone growth factors, therefore autograft tooth could be recycled as the innovative biomaterial. Conclusion: The present results indicate that the autograft dentin materials can be used as a bone graft.]]>
