Gingival depigmentation data set

OBJECTIVE: Physiologic gingival pigmentation may negatively impact smile esthetics, particularly in individuals with high smile lines. This randomized clinical trial aimed to compare the clinical effectiveness of three minimally invasive depigmentation techniques: microneedling with Triphala Curna, microneedling with vitamin C, and 445-nm diode laser ablation. MATERIALS AND METHODS: Eighteen systemically healthy patients with physiologic gingival pigmentation were enrolled and allocated into three groups (n = 6 each) via block randomization. Group 1 received microneedling followed by topical Triphala Curna application; Group 2 received microneedling with vitamin C; and Group 3 underwent diode laser depigmentation at a wavelength of 445 nm. In Groups 1 and 2, the procedure was repeated after two weeks. Clinical assessments were performed at baseline, 3 months, and 6 months for gingival pigmentation (Peeran Index), gingival thickness, and patient satisfaction (VAS scores). Statistical analysis included paired and independent t tests, chi-square tests, and descriptive statistics, with significance set at p
