Background and OverviewThere is insufficient literature on the lack of oral pigmentation in the esthetic zone. The aim of this case report was to illustrate the potential impact of loss of gingival pigmentation in the esthetic zone, describe its surgical treatment, and discuss the limited literature on this topic.Case DescriptionAn African American woman with high smile line had localized loss of gingival melanin pigmentation as a complication after implant failure and attempted guided bone regeneration in site 8. A highly pigmented free gingival graft was collected from the facial-attached gingiva of the maxillary posterior teeth and placed onto the previously de-epithelialized recipient bed in the maxillary front. Some pigmentation of the graft was preserved and was visible a few weeks after surgery; some pigmentation recovered over time. At 6 months after surgery, the patient was satisfied with the esthetics. Complete recovery of pigmentation took 12 months, at which time the patient was ready to proceed with the final prosthetic work.Conclusions and Practical ImplicationsGingival pigmentation can be restored using a free gingival graft from a highly pigmented area. When surgical procedures are performed in such cases, loss of gingival pigmentation should be part of the informed consent. However, further research, including histology, is needed.
