The Comparative Efficiency of Four Types of Endodontic Files and Reamers

摘要

Eighty artificial root canals were created in individual sections of bovine bone. Each canal was instrumented to a size 80 using four types of endodontic instruments: Hedstrom files; K-files; reamers; and the new Unifile. Using volume of bone removed per unit of time, the efficiency of instruments was compared. The Hedstrom file proved statistically (p less than .05) to be the most efficient in removing bone from the straight artificial canals.
