Core Tip
Core tip: It is important to prevent the potential adverse consequences that may follow the fracture of endodontic instruments during root canal preparation. Nickel-titanium engine-driven rotary instruments are more prone to fracture than stainless steel hand instruments, but the risks may be reduced by avoiding multiple use of instruments, by careful operative techniques, in particular with small-sized instruments used in sharply curved root canals, by employing reciprocating hand-pieces and by selecting instruments having high torsional and fatigue resistance.
