Abstract

Background: Gum depigmentation is a treatment method to remove melanin hyperpigmentation of the gums, resulting in an aesthetically pleasing rosy smile. A variety of techniques have been used for gingival depigmentation to remove the pigmented layer (8). These include surgical procedures like Cryosurgery, which is followed by COnsiderable swelling and it is also acCOmpanied by increased soft tissue destruction, scalpel surgical techniques, electrosugery, abrasion with diamond bur, lasers. Neodymium-doped Yttrium-aluminum-Garnet (Nd-YAG), Erbium(Er:YAG), Carbon dioxide (CO2), and diode laser. Objectives: To evaluate the anesthesia, swelling, pain, bleeding, healing level, and gum COlor of two CO2 laser and diode laser methods at Can Tho University of Medicine and Pharmacy Hospital. Materials and methods: Study on 38 patients over 18 years old, with two jaws with gingival hyperpigmentation from grade 1 or higher, the upper jaw was treated with CO2 laser, the lower jaw was treated with diode laser at Can Tho University of Medicine and Pharmacy Hospital. Results: 37 cases spray and surface anesthesia, only 1 case of paraapical anesthesia. The diode laser method is more painful than the CO2 laser. Both CO2 and diode laser treatments are painless after 1 week, 4 weeks and 12 weeks of treatment. Wound healing after treatment, both methods were COmpletely epithelialized after 4 weeks of treatment. After 4 weeks, the effectiveness of treating gum hyperpigmentation is 100%, after 12 weeks the recurrence rate from grade 0 to grade 1 on the upper and lower jaw for CO2 laser is 10% and 5.5%, respectively, for diode laser is 11% and 5%.
