Abstract

Purpose: The current study aimed to assess the difference in the clinical outcome of the removal of gingival hyperpigmentation and patient satisfaction of different techniques used for gingival depigmentation, namely; scalpel surgical technique, laser therapy, and vitamin C injection. Subject and methods: A total of thirty patients with gingival hyperpigmentation were included in this study. They were randomly divided into three equivalent groups to be managed with different gingival depigmentation techniques. Group I (control group; n = 10) involved patients treated with the scalpel surgical technique using scalpel 15. Group II (test group 1; n = 10) involved patients treated with diode laser. Group III (test group 2; n = 10) involved patients treated through Ascorbic acid injections. All patients were followed up with for 3 months. Clinically, pain was evaluated for each patient by using visual analog scale (VAS), Calculation of surface area of gingival pigmentation and re-pigmentation was assessed. Calculation of darkness value of gingiva using Image J intensity was assessed. Results: Laser and Ascorbic acid groups showed less pain at the surgical site and with the follow up, all three groups showed no sign of re-pigmentation after 3 months. Conclusion: The aesthetic effects of these three alternative treatments were outstanding and comparable, according to the current study with significant difference statically in pain perception, intensity darkness value and insignificant difference statically in re-pigmentation after 3 months follow up.
