Funded Activity Summary

Dental disease affecting the supporting structures of teeth (the periodontium), is prevalent in our society. Periodontal disease results in destruction of bone around teeth, loosening of teeth, compromised chewing function, and tooth loss. Over the last twenty years reports into the effects of prostaglandin E2 (PGE2) on the skeleton have been divided and controversial. While historically PGE2 has been reported to promote bone resorption, more recently it has been demonstrated that when PGE is placed in contact with mandibular bone, adjacent to erupted teeth, new bone and cementum formation occurs. The ability of PGE2 to induce new bone formation indicates a potential use for PGE2 in the management of bone loss associated with periodontal diseases, and the formation of new bone around dental implants, and around teeth following orthodontic movement. Growth factors are active in healing and have valuable applications in augmenting wound repair. Osseous and dental tissues are rich in growth factors, and these factors are involved with the regulation of bone metabolism as well as tissue repair, thus the action of PGE2 on the periodontium is most likely regulated via these factors. Since regeneration of the periodontium is a fundamental goal of dentistry, any treatment which leads to predictable formation of new connective tissues and their long term stability would be a major clinical advance.
