I. Objectives This study investigated the quantity of debris which was extruded apically after canal instrumentation using different types of enlarging instrument in endodontic resin models. II. Materials and Methods Five groups of 9 endodontic resin model were instrumented using each different technique：hand instrumentation without early coronal flaring, hand instrumentation after early coronal flaring, and three nickel-titanium engine-driven instrumentations(Hero 642, Protaper, K3) after early coronal flaring.(omitted)
