Movimento reciprocante - sistemas Reciproc e Waveone : revisão de literatura.

Abstract

After the development of the Niti alloy in endodontics, many faster and more efficient mechanized instrumentation systems have been produced among them the Reciproc e Waveone systems. These reciprocating systems when compared to continued rotation, they have showed more advantages. Moreover, the objective proposed on this study, through literature review is to contribute to the knowledge of the Reciproc and WaveOne systems, which use the reciprocating or oscillatory movement, as well as to describe the technic, their characteristics, vantages and disadvantages. Studying the comportment of these systems as a way to guarantee a faster root canal procedure, effective and the possibility of reducing cycle fatigue of the instruments, and extrusion of debris to the periapex of the tooth. The results consider Reciproc and WaveOne a new concept of instrumentation, which use rotatory and anti-rotatory movement that reduces the risk of torsion, time working and the possibility of crossed contamination. Therefore, the Reciproc showed more resistance when submitted to chlorite and cycle fatigue in comparison to WaveOne, thus occasioning less geometric alteration on the root canal, more flexibility and cutting efficiency.
