Owing to their exceptional properties, high-entropy alloys(HEAs) and high-entropy materials have emerged as promising research areas and shown diverse applications. Here,the recent advances in the field are comprehensively reviewed,organized into five sections. The first section introduces the background of HEAs, covering their definition, significance,application prospects, basic properties, design principles, and microstructure. The subsequent section focuses on cutting-edge high-entropy structural materials, highlighting developments such as nanostructured alloys, grain boundary engineering,eutectic systems, cryogenic alloys, thin films, micro-nano-lattice structures, additive manufacturing, high entropy metallic glasses, nano-precipitate strengthened alloys, composition modulation, alloy fibers, and refractory systems. In the following section, the emphasis shifts to functional materials, exploring HEAs as catalysts, magneto-caloric materials, corrosion-resistant alloys, radiation-resistant alloys, hydrogen storage systems, and materials for biomedicine. Additionally, the review encompasses functional high-entropy materials outside the realm of alloys, including thermoelectric, quantum dots, nanooxide catalysts, energy storage materials, negative thermal expansion ceramics,and high-entropy wave absorption materials. The paper concludes with an outlook, discussing future directions and potential growth areas in the field. Through this comprehensive review,researchers, engineers, and scientists may gain valuable insights into the recent progress and opportunities for further exploration in the exciting domains of high-entropy alloys and functional materials.

目的:本研究旨在对比传统方法与计算机辅助方法在处理下颌第一磨牙远舌根根管疏通时的效果差异。方法:选取了25个离体下颌第一磨牙,重建三维模型后,每个牙齿3D打印6份模型。将模型牙分为两组(n=75):传统组与计算机辅助组。2组由相同3名牙体牙髓住院医师分别完成25个牙齿的根管疏通。记录两组根管疏通率、完成时间及疏通后根管偏移情况。结果:3人在传统组中平均疏通完成率为56.00%,而计算机辅助组的根管疏通完成率为74.67%,效率提高了33.34%,显著高于传统组(P0.05)。计算机辅助组在根管疏通后在距离根尖1 mm与4 mm处根管偏移量上明显低于传统组(P<0.05),且疏通后根管的中心率也显著高于传统组,根管切削量更少(P<0.05)。结论:研究表明采用计算机辅助分析术前CBCT影像的方法对下颌第一磨牙远舌根管的疏通时间并无显著影响。然而,计算机辅助分析能够更准确地选择合适的器械和疏通方法,从而在保持根管原有形态的同时,减少疏通过程中可能出现的台阶等并发症,显著提高疏通效率和质量。
