Mechanized endodontic: the evolution of continuous rotary systems
Journal Title: RSBO - Year 2009, Vol 6, Issue 3
Abstract
Introduction: None phase of endodontic treatment has showed significant evolution as the instrumentation, due to the expressive development of the rotary files, what justifies the need of studies regarding this matter.Objective: The aim of this study was to carry a review about the evolution of continuous rotary systems, showing individuals features, action mechanism,shaping technique, advantages and disadvantages of each system and corrections of possible failures.Literature review: Through comparison, the main factors regarding the use of rotary systems were analyzed in general in the literature review,such as cleaning and shaping,ability to remove smear layer and debris, apical transportation,apical extrusion of debris, loss of working length,zips formation, stairs and perforations,file deformations and fractures’ rate and working time for root canal shaping.Conclusion: It was concluded that the systems ProTaper Universal, K3, Hero, Race and MTwo are the most representative in the actual moment. The systems BioRace and Twisted File are the most promising because studies about them still need to be accomplished.
