Role of insulin-like growth factor in the orthodontic periodontal tissue remodeling / 中国组织工程研究

ABSTRACT

BACKGROUND:Orthodontic treatment is a mechanical force for tooth to cause the remodeling of periodontal tissue, produced by the tooth movement. The main aspect of orthodontic periodontal tissue remodeling is the alveolar bone. Insulin-like growth factor is an important factor in the remodeling of periodontal tissue, which plays an important role in the growth, differentiation and growth of the cels. OBJECTIVE:To review the role of insulin-like growth factors in periodontal tissue remodeling. METHODS: A computer-based retrieval of PubMed, CNKI and Guizhou Province Digital Library Database was performed to search articles related to the role of insulin-like growth factors in periodontal tissue remodeling. The keywords were “insulin-like growth factor; periodontal tissue; remodeling” in English and Chinese, respectively. RESULTS AND CONCLUSION: Insulin like growth factor belongs to the insulin family, a kind of peptides, which can promote the migration, proliferation, differentiation, colagen and matrix synthesis and alkaline phosphatase activity of osteoblasts, fibroblasts and mesenchymal cels in the periodontal ligament. It also plays an important role in the repair of injury. During orthodontic treatment, the use of suitable orthodontic force combined with insulin-like growth factor can promote periodontal tissue remodeling, accelerate the orthodontic tooth movement and shorten the treatment time for patients.
