In enhancing smile aesthetics, managing gingival hyperpigmentation has become increasingly important. Gingival hyperpigmentation can often affect individuals psychologically, prompting many individuals to seek treatment. Microneedling (MN) is emerging as a popular solution for minimizing gingival hyperpigmentation through a minimally invasive approach. In contrast, the scalpel technique is an established surgical intervention to remove pigmented tissue directly. This study investigated the effectiveness of these two techniques in terms of clinical and patient-related outcomes.
This randomized control clinical study included 20 subjects with hyperpigmentation in both maxillary and mandibular arches. One arch of each subject was randomly allocated to MN using the coin toss method, and the other arch was assigned to the scalpel technique. Intraoperative bleeding, postoperative pain scores, wound healing index, Dummett oral pigmentation index (DOPI), and Hedin melanin index (HMI) were evaluated.
MN showed significantly better results in terms of pain, bleeding scores, DOPI, and HMI (<0.01). In contrast, the scalpel technique revealed significantly superior results in terms of wound healing.
Being a gold standard, the scalpel technique offers precision but is accompanied by more bleeding and less patient compliance due to its invasiveness. Conversely, the MN technique emerges as an advanced technique, demonstrating less pain and bleeding, thus enhancing patient comfort and overall satisfaction, aligning with the evolving preferences for minimally invasive dental procedures.
在提升微笑美学方面，处理牙龈色素沉着变得越来越重要。牙龈色素沉着常常会在心理上影响个体，促使许多人寻求治疗。微针疗法（MN）正作为一种通过微创方法使牙龈色素沉着最小化的流行解决方案而兴起。相比之下，手术刀技术是一种成熟的手术干预方法，可直接切除色素沉着组织。本研究从临床和患者相关结局方面调查了这两种技术的有效性。
这项随机对照临床研究纳入了20名上颌和下颌牙弓均有色素沉着的受试者。使用抛硬币的方法将每位受试者的一侧牙弓随机分配至微针疗法组，另一侧牙弓分配至手术刀技术组。评估术中出血情况、术后疼痛评分、伤口愈合指数、达米特口腔色素沉着指数（DOPI）和赫丁黑色素指数（HMI）。
微针疗法在疼痛、出血评分、DOPI和HMI方面显示出显著更好的结果（<0.01）。相比之下，手术刀技术在伤口愈合方面显示出显著更优的结果。
作为金标准，手术刀技术具有精确性，但由于其侵入性，会伴随更多出血且患者依从性较差。相反，微针疗法技术作为一种先进技术，显示出疼痛和出血较少，从而提高了患者的舒适度和总体满意度，符合对微创牙科手术不断变化的偏好。
