	abstract = {In cases of damaged oral tissues, traditional therapies, such as a root canal, replace the injured tissue with a synthetic material. However, while the materials currently used can offer structural replacement of the lost tissue, they are incapable of completely replacing the function of the original tissue, and often fail over time. This report describes a tissue engineering approach to dental pulp tissue replacement utilizing cultured cells seeded upon synthetic extracellular matrices. Human pulp fibroblasts were obtained and multiplied in culture. These cells were then seeded onto three different synthetic matrices: scaffolds fabricated from polyglycolic acid (PGA) fibers, a type I collagen hydrogel, and alginate in an effort to examine which matrix is most suitable for dental pulp tissue formation. In addition, methods previously developed for seeding and culturing pulp cells on PGA were optimized. Culturing cells on PGA resulted in a very high cell density tissue with significant collagen deposition. No cell proliferation was observed on alginate, and the growth of cells in collagen gels after 45 days was only moderate. These studies indicate dental pulp-like tissues can be engineered, and this may provide the first step to engineering a complete tooth.},
