Canal preparation using only one Ni‐Ti rotary instrument: preliminary observations

AIM: To describe a novel canal preparation technique using only one Ni-Ti rotary instrument. SUMMARY: In this novel technique, the canal is negotiated to the working length with a size 08 hand file. Then, the canal preparation is completed with an F2 ProTaper instrument used in a reciprocating movement. In larger canals, the use of additional hand files may be required to complete the apical enlargement. *A novel canal preparation technique is introduced using only one Ni-Ti rotary instrument in a reciprocating movement. *The advantages of the technique include a reduced number of instruments, lower cost, a reduced instrument fatigue and the elimination of possible prion cross-contamination associated with the…
