Abstract

This investigation has aimed to compare the efficiency of clinical depigmentation and repigmentation rate of erbium chromium–doped: yttrium, scandium, gallium, garnet (Er,Cr:YSGG) and diode lasers during a 1-year follow-up and to evaluate patient satisfaction. Twenty-two participants were divided into Er,Cr:YSGG laser and diode laser groups using computer-aided randomization. Dummett Oral Pigmentation Index (DOPI) and photographic assessment with ImageJ Software version 10.2 were performed at the preoperative period and postoperative 1st month, 6th month, and 12th month. Moreover, the study assessed intra- and postoperative intensities of pain and postoperative patient aesthetic satisfaction using the Visual Analog Scale in both groups. The median values of DOPI did not differ statistically between the groups according to time (p > 0.05). In the Er,Cr:YSGG group, the extension of repigmentation was less as compared to the diode group at 1-year follow-up (p = 0.045). In the Er,Cr:YSGG group, the patients felt less intraoperative pain and discomfort compared to the diode group (p = 0.007). No significant differences were found between the two groups in terms of patient aesthetic satisfaction at the 1st and 12th months. The findings indicate that diode and Er,Cr:YSGG lasers can be used safely in depigmentation treatment, while the Er,Cr:YSGG laser has been shown to have superiorities in pain management and patient comfort parameters. Clinical Trial No.: NCT05304624.
