RESUMEN
BACKGROUND: Physiologic gingival hyperpigmentation (PGH) is a benign condition that results from increased melanin production and is prevalent among darker skin individuals. Although the use of lasers for PGH has gained popularity in recent years, the lasers being used are mostly ablative, and act through a non-selective tissue damage mechanism. AIMS: The objective of this study was to evaluate the use of a non-ablative 694-nm Q-switched ruby laser (QSRL) for the depigmentation of PGH. METHODS: A retrospective single-center study of patients diagnosed with PGH and treated with a QSRL Between March 2019 and November 2020. RESULTS: Four patients were treated with QSRL for 1-3 sessions, until complete depigmentation was achieved. The average follow-up was 11 months (range 7-18 months) with no patient exhibiting re-pigmentation. Adverse events included mild local tenderness and transient erosions in two patients. CONCLUSION: The 694-nm QSRL is a novel and promising safe and effective method for treating PGH with the advantages of being a non-ablative modality that minimizes tissue damage and optimizes the outcome.

Resorption of alveolar process generally occurs following tooth extraction, and this process may cause a variety of jaw deformities. Bone deformities in the aesthetic zone impair the appearance, quality, and prognosis of the definitive restoration. The rotated palatal flap is a surgical modality that can be used to reduce or prevent alveolar resorption and assist in the repairing of exisiting defects. This presentation demonstrates the application of the rotated palatal flap in a variety of clinical cases as a means of addressing such resorption.
