Abstract:

Avulsion causes the immediate injury of the periodontium. Treatment for avulsion aims to restore the morphology and function of periodontal ligament. Tissue engineering is a technology which utilizes the seeding cells，growth factor and scaffold materials for repairing the damaged tissue in tissue regeneration. It is thought as a new approach to the periodontal ligament regeneration. In this paper，we highlight recent research and application progress in the treatment of periodontal ligament regeneration in tooth avulsion，involving the cell-free and cell-based tissue regeneration.

Key words: tooth avulsion, periodontal ligament regeneration, cell-based tissue regeneration, cell-free tissue regeneration
