Presurgical evaluation revealed generalized melanosis of the buccal gingiva and a lack of keratinized tissue around implants at sites #4 and #13. No pigmentation was noted on the palatal tissues.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Thick free gingival grafts were harvested bilaterally from the non\u2010pigmented palate and secured to the recipient sites with bioabsorbable sutures. Hemostasis was achieved at the palatal donor sites with moistened gauze, and an acrylic stent was delivered for patient comfort.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Both palatal donor sites healed with spontaneous pigmentation. The pigmentation intensified with time but resulted in no adverse outcome.<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> Post\u2010surgical healing in patients with gingival pigmentation is not entirely predictable, as multiple studies have demonstrated widely inconsistent results in regards to gingival pigmentation upon healing. When performing periodontal plastic surgery in patients with pigmented oral tissues, it is important to discuss all possible outcomes, including spontaneous
