| Outline of Final Research Achievements |
Enamel Matrix Derivative(EMD), which is commonly used as a material for periodontal tissue regeneration, a substance consistent with the partial sequence of amelogenin exon 5 was identified. We compare the experiment has compared the peptide with EMD from the view point of angiogenesis. Periodontal tissue defects were artificially prepared in the maxillary molar region of rats, and a new synthetic peptide or EMD was applied to the site of defect. Spicemens at this site were prepared 3, 5, and 7 days after surgery, and histopathologically and immunohistochemically examined using anti-type Ⅲ collagen antibody. Like EMD, novel synthetic peptide promoted the early wound healing process in the periodontal tissues compared to the control, suggesting that it has action accelerate periodontal regeneration.
