Alveolar bone deficiency is a major postoperative complication in the treatment of traumatic injuries, periodontal diseases and likewise. Hence, alveolar bone repair remains a major hurdle in tissue engineering. Autogenous bone can be wellthought- of as benchmark for bone grafting sans its limitations and complications. In order to overcome these limitations, there is an increased demand of bone graft materials that led to numerous studies on different techniques and materials for bone regeneration over the years. Dentin and bone having same biochemical similarities led to the idea of using it as a bone regenerative material. Demineralized dentin matrix (DDM), an organic material obtained from dentin has been shown to possess osteogenic capacity. Demineralized dentin matrix may prosper in future endodontic world as an apexification material and as a permanent root canal filling material as well. Quick in bone forming as compared to conventional bone graft, this material is a boon to the dental world in this era. This manuscript reviews various studies on different types of DDM as a bone grafting material, and also summarizes the suggested pathway of bone regeneration.
