Abstract
Objectives: Gingival hyperpigmentation is an increase in pigmentation beyond normal levels of the gingival mucosa, which is primarily due to increased melanin pigmentation. This is a physiological condition, not a pathology, but greatly affects the aesthetics and psychology of the patient, especially patients with a gummy smile or excessive gum exposure. Treatment of gingival hyperpigmentation by diode laser has advantages such as easy manipulation of gingival reshaping, short treatment time, minimal heat damage, hemostatic effect, and less complications such as pain and inflammation. Infection after surgery. This study aimed to evaluate the results of treatment of gingival hyperpigmentation by Diode Laser.
Methods: Prospective description on 15 patients diagnosed with gingival hyperpigmentation and treated with Diode Laser at Hue University of Medicine and Pharmacy Hospital from 01/2022 to 03/3023.
Results: The bleeding rate after treatment: 40% mild bleeding, 60% no bleeding and the bleeding rate after 1 week: 6.67% mild bleeding, 93.3% no bleeding, no cases left bleeding after 1 month. There was only 1 case of mild swelling and pain immediately after treatment, no patient had any swelling or pain after 1 week and 1 month. The rate of mild pain during and immediately after the procedure: 93.33% and 73.33%, after 1 week the rate of complaints about mild pain: 20% and after 1 month no pain symptoms in all patients (p < 0.01). The degree of reduction in the area of gingival hyperpigmentation after treatment was also evaluated very well (93.33%) and good (6.67%). There was no statistically significant difference for the red change for hemoglobin R (> 0,05) before and after procedure , whereas, there was a statistically significant difference for green for cytoplasmic G (> 0,05), and for blue color for the melanin component B (p = 0.0001).
Conclusions: The use of a 445 nm Diode Laser was shown to be a safe and effective treatment modality that provides optimal aesthetics with minimal discomfort in patients with gingival hyperpigmentation
