Aesthetic concerns are increasing rapidly; thus, several approaches have been suggested for treating gingival melanin pigmentation. Lasers have been reported as an effective new tool, and the Nd:YAG laser beam has an affinity for melanin and haemoglobin. However, ceramic gingival bur is simple and has less bleeding effect during operation than conventional techniques. This study aimed to compare the outcomes of gingival depigmentation using the Nd:YAG laser and ceramic bur in two different groups (smokers and non-smokers). A total of 40 patients presenting with gingival melanin pigmentation were enrolled in this split-mouth study. The sample was divided into two groups: smokers and non-smokers. Treatment was performed using the Nd:YAG laser (3 W, 60 mJ/pulse, and 50 Hz) and ceramic bur with a one-week interval between the two methods. Clinical indices were recorded, including intraoperative bleeding, wound healing, post-operative pain, and the recurrence of pigmentation, and follow-up periods were determined in the 3rd, 6th, and 9th months postoperatively. Both treatments promoted a similar pain experience and recurrence rate of pigmentation ( > 0.489, = 1.000, respectively). Bleeding during surgery and complete healing recovery after one week were statistically significantly higher when using ceramic bur ( = 0.00, = 0.041, respectively). Concerning the effect of smoking on the treatment, a higher recurrence rate was observed in SG than N-SG in laser sites (50%, and 95%, respectively) and bur sites (60%, and 85%, respectively), but statistically no significant difference was observed ( > 0.080). In conclusion, both procedures are adequate for aesthetic gingival depigmentation treatment. The Nd:YAG laser showed greater effectiveness in controlling bleeding, while ceramic bur showed a faster clinical recovery. Furthermore, smokers were more likely to have low depigmentation treatment stability.
美学方面的问题正在迅速增加；因此，已经提出了几种治疗牙龈黑色素沉着的方法。激光已被报道为一种有效的新工具，而钕钇铝石榴石（Nd:YAG）激光束对黑色素和血红蛋白具有亲和力。然而，陶瓷牙龈车针操作简单，与传统技术相比，手术过程中的出血效应较小。本研究旨在比较在两个不同组（吸烟者和非吸烟者）中使用Nd:YAG激光和陶瓷车针对牙龈色素沉着治疗的效果。共有40例牙龈黑色素沉着患者参与了这项双侧对照研究。样本分为两组：吸烟者和非吸烟者。使用Nd:YAG激光（3W，60mJ/脉冲，50Hz）和陶瓷车针进行治疗，两种方法之间间隔一周。记录临床指标，包括术中出血、伤口愈合、术后疼痛和色素沉着复发情况，并在术后第3、6和9个月确定随访期。两种治疗方法引起的疼痛体验和色素沉着复发率相似（分别>0.489，P = 1.000）。使用陶瓷车针时，手术期间的出血和一周后的完全愈合恢复在统计学上显著更高（分别P = 0.00，P = 0.041）。关于吸烟对治疗的影响，在激光治疗部位，吸烟组（SG）的复发率高于非吸烟组（N - SG）（分别为50%和95%），在车针治疗部位也是如此（分别为60%和85%），但在统计学上未观察到显著差异（P>0.080）。总之，两种方法都适用于美学牙龈色素沉着治疗。Nd:YAG激光在控制出血方面显示出更大的有效性，而陶瓷车针显示出更快的临床恢复。此外，吸烟者的色素沉着治疗稳定性更可能较低。
