摘要:SummaryTooth 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 NaNbO3/ZnO binary nanocomposite. Moreover, the NaNbO3/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 NaNbO3/ZnO binary nanocomposite under ultrasonic irradiation. The piezoelectric potential of NaNbO3/ZnO was found to be 3.75 V. The binary nanocomposite’s antibacterial activity was proven to be efficient againstEscherichia coliwith the inhibitory zone of 21 mm and complete removal of bacteria.Graphical abstractDisplay OmittedHighlights•NaNbO3/ZnO binary nanocomposite was synthesized by hydrothermal method•NaNbO3/ZnO binary nanocomposite was evaluated as a piezocatalyst•The formation of p-n heterojunction enhances the catalytic activity•NaNbO3/ZnO binary nanocomposite can be used for non-destructive tooth cleaningChemistry; Materials science; Materials chemistry; Materials property
