| description | Introduction: Successful treatment depends on the endodontic
removal of microorganisms with chemomechanical preparation.
Rotary NiTi instruments offer greater flexibility and efficiency in
the court, but the failure of these can occur unexpectedly by metal
fatigue. Objective: To determine in vitro the first instrument that
this fracture and the number of uses before observe in Mtwo® and
ProTaper® rotary systems. Methodology: Experimental study in
vitro preparation of comparative descriptive results. A total of 50
Rotary ProTaper® instruments and 40 Mtwo® was used to prepare
Maillefer® acrylic cubes with simulated curves recorded lima which is
the first of each series to be fractured and how each game uses limes
stand before fracture. Results: The number of uses before breaking
for ProTaper® is Mtwo® 3.9 and 9.7 is the first file in fractured
ProTaper® is the F1 and Mtwo® is the 25/.06 (p 0.0001). Conclusion:
The duration of Mtwo® rotary instruments is greater than ProTaper®.
Relatively high incidence of fracture for F1 ProTaper® instrument
system at four uses and for instrument 25/.06 of Mtwo® system was
observed 10 uses, with a low incidence of deformation or change in
macroscopically identifiable structure before failure occur. |
