Introduction:Intraoral soft tissue esthetics has become a significant aspect of dentistry and clinicians are faced with achieving acceptable gingival esthetics as well as addressing biologic and functional problems. Aim of study: was to evaluate the effect of diode laser irradiation on gingival depigmentation. Materials and methods: 3 watts continuous mode diode laser was used to remove gingival hyperpigmentation of dogs. Specimens were divided according to the follow up periods of (1, 2, 4 and 8 weeks) where the experimental specimens were contralateral to the control ones. Specimens were evaluated pre- and post-treatment histologically using H&E, histochemically using Masson Fontana and ultrastructurally by transmission electron microscope. Results:histological, histochemical and ultrastructural evaluation revealed a statistically significant decrease in melanin content in the follow up periods compared to the baseline. Meanwhile, the recurrence of melanin was observed more in groups of 4 and 8 weeks after laser irradiation yet did not reach the baseline.
