Comparison of the Relative Risk of Molar Root Perforations Using Various Endodontic Instrumentation Techniques.

Abstract

One hundred canals in the mesial roots of sixty mandibular molars were instrumented using five techniques. The remaining twenty canals became uninstrumented controls. A standard technique without flaring and four techniques with flaring were evaluated. Two of the flare techniques used only hand instrumentation (circumferential and anticurvature) while two used additional engine-driven instrumentation (round burs and Gates-Glidden burs). Of the flare techniques, hand instrumentation used in an anticurvature manner showed significantly less risk (less than .005) to the bifurcation root surface. The engine-driven techniques were not significantly different than circumferential hand instrumentation in their risk to the bifurcation area.
