Tooth discoloration and plaque formation are serious issues for dental healthcare professionals across the world. Although traditional hydrogen peroxide-based cleaning methods are efficient, they can cause enamel demineralization, periodontal irritation, and toxicity. Also, these treatments are time-taking. Here, we present a noninvasive, safe, and simple tooth cleaning approach by using the piezoelectric phenomenon. After 6 h of vibrations, contaminated teeth can be significantly cleaned by the NaNbO/ZnO binary nanocomposite. Moreover, the NaNbO/ZnO binary nanocomposite-based piezocatalysis tooth cleaning procedure causes far less harm to enamel and biological cells in comparison to hydrogen peroxide-based cleaning methods. To evaluate its functionality, organic dyes were degraded by piezoelectric effect of NaNbO/ZnO binary nanocomposite under ultrasonic irradiation. The piezoelectric potential of NaNbO/ZnO was found to be 3.75 V. The binary nanocomposite's antibacterial activity was proven to be efficient against with the inhibitory zone of 21 mm and complete removal of bacteria.
牙齿变色和牙菌斑形成是全球牙科保健专业人员面临的严重问题。尽管传统的基于过氧化氢的清洁方法效率很高，但它们会导致牙釉质脱矿、牙周刺激和毒性。此外，这些治疗方法耗时较长。在此，我们提出一种利用压电现象的无创、安全且简单的牙齿清洁方法。经过6小时的振动，被污染的牙齿可以被NaNbO/ZnO二元纳米复合材料显著清洁。此外，与基于过氧化氢的清洁方法相比，基于NaNbO/ZnO二元纳米复合材料的压电催化牙齿清洁程序对牙釉质和生物细胞造成的损害要小得多。为了评估其功能，在超声辐射下，通过NaNbO/ZnO二元纳米复合材料的压电效应降解有机染料。发现NaNbO/ZnO的压电电位为3.75 V。二元纳米复合材料的抗菌活性被证明对具有21毫米的抑菌圈且能完全去除细菌有效。
