Formación de fisuras radiculares del tercio apical en dientes humanos, causadas por la instrumentación de dos sistemas reciprocantes. Estudio ex vivo

Abstract

Root canal preparation is one of the most important steps in the success of endodontic treatment. The introduction of new mechanical preparation systems based on nickel titanium alloys, have achieved a safer endodontic practice reducing procedural errors since these instruments have high cutting efficiency and affected the centrality and the original anatomy of the root canals and optimizing Working time A market reciprocating movement was introduced with the aim of reducing the separation of instruments by torsion or cyclic fatigue. However, this bidirectional movement in the apical zone can produce greater pressure compared to a continuous rotation system.
