Nanoparticles based on metal and metallic oxides have become a novel trend for dental applications. Metal nanoparticles are commonly used in dentistry for their exclusive shape-dependent properties, including their variable nano-sizes and forms, unique distribution, and large surface-area-to-volume ratio. These properties enhance the bio-physio-chemical functionalization, antimicrobial activity, and biocompatibility of the nanoparticles. Copper is an earth-abundant inexpensive metal, and its nanoparticle synthesis is cost effective. Copper nanoparticles readily intermix and bind with other metals, ceramics, and polymers, and they exhibit physiochemical stability in the compounds. Hence, copper nanoparticles are among the commonly used metal nanoparticles in dentistry. Copper nanoparticles have been used to enhance the physical and chemical properties of various dental materials, such as dental amalgam, restorative cements, adhesives, resins, endodontic-irrigation solutions, obturation materials, dental implants, and orthodontic archwires and brackets. The objective of this review is to provide an overview of copper nanoparticles and their applications in dentistry.
基于金属和金属氧化物的纳米颗粒已成为牙科应用的一种新趋势。金属纳米颗粒因其独特的形状依赖性特性，包括可变的纳米尺寸和形态、独特的分布以及大的表面积与体积比，而常用于牙科领域。这些特性增强了纳米颗粒的生物物理化学功能化、抗菌活性和生物相容性。铜是一种储量丰富且价格低廉的金属，其纳米颗粒的合成具有成本效益。铜纳米颗粒易于与其他金属、陶瓷和聚合物混合并结合，并且在化合物中表现出物理化学稳定性。因此，铜纳米颗粒是牙科常用的金属纳米颗粒之一。铜纳米颗粒已被用于增强各种牙科材料的物理和化学性能，如牙科汞合金、修复性粘固剂、粘合剂、树脂、根管冲洗液、充填材料、牙科植入物以及正畸弓丝和托槽。本综述的目的是概述铜纳米颗粒及其在牙科中的应用。
