RESUMO
Concentrated growth factor (CGF) is a newer form of autologous platelet concentrate with an extra fibrin matrix and more growth factors than that observed with platelet-rich fibrin, due to its different centrifugation process. This case series evaluates the early wound healing with CGF membrane as a periodontal bandage after depigmentation. Three individuals were selected for a split-mouth study. After surgical depigmentation, the test site received CGF membrane. Both groups were covered by a periodontal pack. Participants were assessed on the 3rd and 5th days using a Visual Analog Scale and a Healing Index. Epithelization test was done with toluidine blue on the 5th day and tissue samples were taken for histological evaluation. The application of CGF membrane showed better healing and lesser inflammatory cells. Thus, a CGF membrane is helpful in protecting the raw wound region of depigmented sites, improving patient comfort, and for better healing.
