Evaluation of the Efficacy of Blue Laser in the Management of Gingival Hyperpigmentation Using Contact vs. Non-contact Mode
Sponsor: Beirut Arab University
Summary
The goal of this clinical trial is to compare clinical and digital color parameter results of gingival depigmentation using blue laser in both contact and non- contact modes in patients with physiological gingival hyperpigmentation. The main questions it aims to answer are: * Which intervention will provide less pain? * Which intervention will provide better gingival depigmentation? Participants will undergo: * Mechanical plaque removal * Infiltration using Articaine 4% * Blue diode laser (445 nm) application to the gingiva either from a 2-mm distance in one group or directly to the gingiva in the other group.

Interventions
Gingival depigmentation using blue laser in non-contact mode
Infiltration anesthesia using 4% Articaine was given. Blue light laser (445 nm, 1.5 W) was applied to patients with physiologic hyperpigmentation using 300 µm fiber-optic tip at a distance of 2mm from the target area in constant movement until gingival blanching was observed.
Gingival depigmentation using blue laser in contact mode
Infiltration anesthesia using 4% Articaine was given. Blue light laser (445 nm, 1 W) was applied to patients with physiologic hyperpigmentation using 300 µm fiber-optic tip directly touching the target area until ablation was observed.
