Abstract

Background: Racial gingival hyper pigmentation is a common esthetic concern, which is aggravated in patients with excessive gingival display, laser ablation is recognized as the most effective and reliable easy handling technique.

Aim of the Study: The aim of this study was to evaluate the effect of the low level diode laser (LLDL) therapy versus surgical abrasion in the treatment of racial gingival pigmentation clinically by assessment of melanin pigmentation index (MPI), wound healing index (WHI) and visual analog scale (VAS).

Subjects and Methods: The present study is randomized, clinical split mouth design, twenty patients of both genders with age ranged from 20 to 40 years, all have racial gingival pigmentation score 2 were included in this study, all patients were non pregnant or lactating, free from systemic diseases, or any disease that cause oral pigmentation), all patients were non-smokers and had esthetic concern and good oral hygiene, forty sites in twenty patients were divided randomly into two groups (A and B), group A were treated by surgical abrasion at first was performed by large size round carbide bur started from the mucogingival junction toward the free gingival margin, including papillae, the wound covered by non-eugenol periodontal dressing, group B: were treated by LLDL without dressing post treatment, the treated site was irradiated for a single time, LLDL was delivered by a 600-μm diameter fiber, 808 nm ± 10 nm wavelength with output power 3 Watt.

Results: There was improvement in MPI in both groups through follow up periods with superiority of LLDL group.

Conclusion: Low level diode laser can be considered as a reliable mean for elimination of melanotic lesion of gingiva and is well tolerated by patients.
