Periodontal Regeneration Using the Mixture of Human Tooth-ash and Plaster of Paris in Dogs

The ultimate goals of periodontal therapy include not only the arrest of periodontal disease progression, but also the regeneration of structures lost to disease where appropriate. An appropriate periodontal regeneration should be restored original normal alveolar bone, periodontal ligament, and cementum which is destructed by the periodontal disease. Additionally, the periodontal ligament fibers must be anchored into the cementum. However, periodontal healing following a conventional periodontal treatment occurred junctional epithelial attachment. As a result, various materials such as bone replacement grafts, barrier membranes, and biologic modifiers currently used for the regeneration of periodontal tissue defects.1) GTR technique is for the periodontal tissue regeneration by inducing the fibroblast or progenitor cells originated from PDL not allowing epithelium and gingival connective tissue ingrowth. Non absorbable membrane has some problems in that early exposure of membrane and additional surgery for the removal of the membrane. It has been documented that bacterial infection caused by the early exposure of the membrane was one of the GTR failure factors and even if the GTR succeed, the amount of the tissue regeneration was decreased. To overcome these problems, bioresorbable membrane was used, but bioresrobable membrane had some disadvantages in maintaining the space for
