An In-Vivo Study of Effects of Platelet-Rich Plasma on Transforming Growth Factor-β1 and Matrix Metalloprotein 9 Expression in Traumatic Ulcers with Diabetes Mellitus.

Objective:  Diabetes mellitus is not only characterized by alterations in the wound healing process but also during oral ulcer healing. The platelet-rich plasma (PRP) can be used to stimulate the healing process. This study was performed to analyze the effect of PRP on traumatic ulcers with diabetes mellitus in an animal model by analyzing the expression of transforming growth factor β1 (TGF-β1) and matrix metalloprotein 9 (MMP-9).
