摘　　要：牙髓及根尖周病的本质是感染,良好的感染控制是病变愈合的前提和基础。根管预备是感染控制的最关键程序,根管系统的解剖形态、根管自身感染程度、根管预备过程中的物理切削以及清理措施的选择均会影响根管感染控制的质量。治疗前应正确评估根管感染程度及解剖形态难度并选择相应的预备方案,合理配合使用成形与清理手段,严重感染的根管建议可选用新型镍钛系统、超声和激光等多种根管清理措施以更好地控制感染,促进组织愈合。The essence of pulp and periapical disease is bacterial infection.Thus,satisfactory infection control is the premise and foundation of healing,in which root canal preparation is a critical procedure.Root canal system anatomy,infection degree, physical cutting during root canal preparation,and certain cleaning measures affect the quality of infection control.Appropriate evaluation of the grades of infected root canals before treatment is necessary because different grades of root canal infection demand various disinfection schedules to facilitate tissue healing and guarantee the long-term success rate of endodontic treatment.
