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.
