背景:陶瓷软组织修剪钻(CeraTip™)最初被引入用于牙龈成形术,但最近已用于牙龈脱色。这项研究的目的是比较新型CeraTip™和金标准手术手术刀技术之间的脱色功效。
方法:八种健康,在两个牙弓中出现中度至重度牙龈色素沉着的非吸烟者被随机分配,其中一个牙弓中的CeraTip™色素沉着作为试验组(TG),而在另一个牙弓中的手术刀色素沉着作为对照组(CG).色素沉着指数用于评估临床表现。治疗时间,疼痛程度,和审美满意度是患者体验的参数。在基线时进行评估,一个星期,一个月,还有三个月.
结果:在所有评估访问中,用Dummet口腔色素沉着指数(DOPI)表示的色素沉着强度,和色素沉着分布由黑色素指数(MI)表示,两组均显著低于基线(p<0.001)。当比较两组时,手术刀脱色有更好的初始临床结果,而CeraTip™的再色素沉着较少,疼痛评分,治疗时间,和更大的审美满意度。然而,差异无统计学意义。
结论:两种技术都成功地消除了牙龈色素沉着,具有可比的临床表现。患者首选CeraTip™色素脱失。

BACKGROUND: The ceramic soft tissue trimming bur (CeraTip™) was initially introduced for use in
gingivoplasty but has recently been used for gingival depigmentation. The aim of this study is to compare the efficacy of depigmentation between the novel CeraTip™ and the gold-standard surgical scalpel technique.
METHODS: Eight healthy, nonsmokers with moderate to severe gingival hyperpigmentation in both arches were randomly assigned for CeraTip™ depigmentation in one arch as the test group (TG) and scalpel depigmentation in the opposite arch as the control group (CG). Pigmentation indices were used to assess clinical performance. Treatment time, pain level, and esthetic satisfaction were the parameters of patient experience. The assessments were performed at baseline, one week, one month, and three months.
RESULTS: At all assessment visits, pigmentation intensity represented by the Dummet oral pigmentation index (DOPI), and pigmentation distribution represented by the Hedin melanin index (MI), were significantly lower than those at baseline (p < 0.001) in both groups. When comparing the two groups, Scalpel depigmentation had better initial clinical outcomes, while CeraTip™ had less visible repigmentation, pain scores, treatment time, and greater esthetic satisfaction. However, none of the differences were statistically significant.
CONCLUSIONS: Both techniques successfully removed gingival hyperpigmentation with comparable clinical performance. The patients preferred CeraTip™ depigmentation.
