Evaluation of Gingival Pigmentation Treatment Efficacy Using 980 Nm Diode Laser
Introduction: Pigmentation is associated with the production of melanin by melanocytes, which is a physiological state in the body. It makes an unpleasant appearance especially for those who have high aesthetic demand. Among different methods, lasers have many advantages in dentistry. Evaluation of gingival pigmentation treatment efficacy using 980 nm diode laser is the purpose of this study.
Material and Methods: 24 patients were qualified for inclusion in the study. Depigmentation was performed using a diode laser. The size of the pigmentation was measured by AutoCAD software before the intervention, 1, 3, and 6 months after the intervention in each patient. Data were analyzed using SPSS software (v.22), Paired t-test, Smirnov-Kolmogorov, and Friedman tests.
Results: The results demonstrated that the area and circumstance of the pigmentation significantly reduced after laser therapy. Also, repigmentation rate evaluation demonstrated that the rate has not changed in the first, third, and sixth months of follow up periods.
Conclusion: The outcomes demonstrated that 980 nm diode laser is effective in treating gingival pigmentation as well as restoring beauty and comfort to the patient.
