The process of wound healing after gingivectomy takes a long time. Fibroblasts are cells that takes an important role in the process of wound healing. One alternative treatment giving medication by applying Robusta coffee bean extract gel which acts as an anti-inflammatory and antioxidant in the wound healing process. The objective was to determine the potential and optimal concentration of Robusta coffee bean extract gel to increase the number of fibroblast cells in post-gingivectomy wound healing phase.
