Variety of treatment approaches have been proposed for esthetic management of dental fluorosis. Microabrasion, bleaching using hydrogen peroxide, and etch bleach seal are commonly used methods. Bleaching using sodium perborate has been used for intracoronal bleaching. Till now, no study has used sodium perborate for extracoronal bleaching of discolored stained teeth.
To evaluate the esthetic improvement of non-pitted fluorosis stains using sodium perborate and compare with etch bleach seal, microabrasion and in-office bleaching with 30% H2O2 on visual assessment scale VAS (primary objective) and to assess any untoward effects including staining, sensitivity, gingival problems within the course of study (secondary objectives).
A randomized control trial with 6 months follow up. Methodology- Twenty children aged 8 to 12 years with non-pitted fluorosis in upper anterior teeth were divided into 4 groups with 5 patients in each group.
All of the techniques showed improvement in esthetics with VAS. However, microabrasion and bleaching using sodium perborate had significantly better results than other 2 techniques.
Sodium perborate showed excellent results in extracoronal bleaching of fluorosed teeth. However a randomized study with large sample size is required to draw a definitive conclusion regarding superiority of one technique over others.
已经提出了多种治疗方法来进行氟斑牙的美学管理。微研磨、用过氧化氢漂白和酸蚀漂白密封是常用的方法。过硼酸钠已用于根管内漂白。到目前为止，还没有研究使用过硼酸钠对变色染色的牙齿进行体外漂白。
使用过硼酸钠评估非凹陷氟斑牙染色的美学改善，并通过视觉评估量表（VAS）与酸蚀漂白密封、微研磨和 30% H2O2 的诊室漂白进行比较（主要目的），并评估任何不良影响，包括在研究过程中的染色、敏感性、牙龈问题（次要目的）。
一项为期 6 个月的随机对照试验。方法：将 20 名年龄在 8 至 12 岁之间、上前牙有非凹陷性氟斑的儿童分为 4 组，每组 5 名患者。
所有技术均通过 VAS 显示出美学改善。然而，微研磨和过硼酸钠漂白的效果明显优于其他两种技术。
过硼酸钠在氟斑牙的体外漂白中显示出极好的效果。然而，需要进行一项具有较大样本量的随机研究，才能得出一种技术优于其他技术的明确结论。
