Cutting efficiency of endodontic files (EFs) has been widely evaluated in the literature. However, its performance depends on the microgeometry of the cutting instrument itself, and this has not been studied in depth. The present review describes basic concepts of cutting instruments, including cutting-tool engineering, the EF relationship, and cutting efficiency among different EF geometric designs during primary treatment and nonsurgical endodontic retreatment.Noncontact lower extremity injuries are commonly related to jumping and l
