Abstract

Objectives: The objective of this study was to compare efficacy of  810nm diode laser and scapel surgery in gingival physiologic melanin hyperpigmentation treatment. Materials and methods: Total 26 arches of 16 patients with bilateral physiologic melanin hyperpigmentaion were recruited in this study. Contralateral quadrants were randomly assigned to receive 810nm diode laser (test group) or scapel technique (control group). Clinical assessments included: pain perception on 1st day and 7th day postoperatively (PO) according to the VAS scale,  intensity of gingival pigmentation at baseline, 1 month and 3 months PO using DOPI (Dummett oral pigmentation index). Wilcoxon signed-rank test and Mann-Whitney one were applied to analyze these data. Results: Postoperative intensity of pain was mild, scapel group showed higher pain but no significant difference when comparing to laser group (p>0.05). At 1 month and 3 months PO, intensity of gingival pigmentation in both laser and scapel groups decreased significantly compared to baseline (p<0.00). However, no statistically significant difference was observed in term of PODI between two grous at both two time points PO (p>0.05). Conclusion: Both 810nm diode laser and scapel technique only cause mild pain and have similar efficacy in improving intensity of gingival pigmentation.
