Abstract

Background: Gingival depigmentation is a treatment to remove the melanin hyperpigmentation of the gums, giving confidence in communication especially when smiling. Different methods have been used for this procedure are scalpel, autologous gingival graft, electrocautery, 90% phenol and 95% alcohol chemotherapy and bur grinding, co2 and diode, Er;Cr:YSGG, NdYag laser. Objectives: Evaluate the level of healing, gum color, swelling, pain, bleeding, of two diode laser and co₂ laser methods at Can Tho University of Medicine and Pharmacy Hospital. Materials and methods: 40 patients over 18 years old, with both upper and lower jaws having gingival hyperpigmentation from level 1 or higher, specifically the upper and lower jaw on the right side were treated with diode laser (diode 1 and diode 4); the upper and lower jaw on the left side were treated with Er;Cr:YSGG laser (Er;Cr:YSGG2, Er;Cr:YSGG3) at Can Tho University of Medicine and Pharmacy Hospital. Results: The diode laser method requires additional topical anesthesia compared to the Er;Cr:YSGG laser. The Er;Cr:YSGG laser method heals 0.5 days earlier and is less painful than the diode laser method. There is no statistically significant difference between the two methods in terms of post-treatment bleeding.
