Nanotechnology is emerging as an interdisciplinary field that is undergoing rapid development and has brought about enormous changes in medicine and dentistry. Nanomaterial-based design is able to mimic some of the mechanical and structural properties of native tissue and can promote biointegration. Nanotechnology has various applications in dentistry, including dentition renaturalization, therapy for dentin hypersensitivity, complete orthodontic realignment in a single visit, covalently bonding diamondized enamel, enhancing properties of root canal sealers, and continuous oral health maintenance using mechanical dentifrobots. A range of synthetic nanoparticles such as hydroxyapatite, bioglass, titanium, zirconia, and silver nanoparticles are proposed for dental restoration. This review focuses on the developments in the field of nanomaterials in dentistry in the form of tissue regeneration materials, implantable devices, nanocomposites, endodontic sealers etc. and issues of patient safety.
纳米技术正在成为一个快速发展的跨学科领域，并给医学和牙科带来了巨大变化。基于纳米材料的设计能够模拟天然组织的一些机械和结构特性，并能促进生物整合。纳米技术在牙科有多种应用，包括牙列再自然化、牙本质过敏症治疗、单次就诊完成正畸完全矫正、共价结合金刚石化牙釉质、增强根管封闭剂性能以及使用机械洁牙机器人持续维护口腔健康。一系列合成纳米颗粒，如羟基磷灰石、生物玻璃、钛、氧化锆和银纳米颗粒被提议用于牙齿修复。本综述重点关注牙科纳米材料领域在组织再生材料、可植入装置、纳米复合材料、根管封闭剂等方面的发展以及患者安全问题。
