Gingival Depigmentation Using Diode Laser 940nm Versus 980nm

Gingival Depigmentation Using Diode Laser 940nm Versus 980nm: A Split-mouth Comparative Clinical Trial

is study aimed to evaluate the effectiveness of two diode lasers of different wave lengths 940nm and 980nm for the treatment of physiologic gingival melanin hyperpigmentation.

Inclusion Criteria:

• Patients of both sexes diagnosed clinically with physiologic gingival pigmentation.
• Pigmentation extending from canine to canine in either upper or lower arch.

Exclusion Criteria:

• Smokers.
• Patients with uncontrolled metabolic disease.
• Immuno-compromised patients.
• Patients with renal disease.
• Patients having coagulation disorders.
• Pregnant and lactating women.
• Evidence about the relation of pigmentation with malignancies.
• History of previous treatment of gingival pigmentation.
