Brief description The regeneration of damaged dental tissues is an emerging area in oral health-based research and is increasingly becoming the forefront of medical-dental interdisciplinary investigations. This idea of repairing damage follows Dr Fiona Wood's unique concept of growing large amounts of specific cells in the lab and spraying them onto damaged tissue, which effectively assists in the repair of the damaged organ. This approach can be similarly used in the dental field by applying prosthetic implants with cells and growth factors, thus enhancing the regeneration of the damaged dental tissue. Artificial replacement of missing teeth has significant limitations when compared with the natural, original tissues in terms of function and appeal. Bridges and dentures have been used for centuries in dentistry but require periodic maintenance or even replacement after a period of time due to usage or loss of adaptation. Thus, if implants and bridgework can be eliminated, so too will be the problems and costs associated with them. This benefit is specifically aimed at the regional community and the public sector, as these patients are generally not in a financial position to restore missing teeth with bridgework, let alone implants. Our aims are: 1. Examine the function of two recently identified growth factors, Osteoclast-Derived Osteoblastic Factor and Emilin and Multimerin-2, through their effect on paradental in vitro cell regeneration. 2. To assess the role played by collagen bioscaffolds, together with explanted cells and growth factors examined during the in vitro studies, in the healing process by comparing teeth transplanted into an existing socket with those transplanted into a prepared site. 3. Evaluate the effect of growth factors, explanted cells and bioscaffolds on regeneration of tissues lost as a result of ligature-induced periodontal infection.
