Resumen
El presente trabajo de investigación, se refiere al tipo de investigación bibliográfica descriptiva, la misma ubica como objeto de estudio en el Estudio Comparativo de la Preparación de Conductos Unirradiculares con Limas Manuales de Titanio (Greater Taper) y (Maillefer) en dientes vitales. Vale resaltar que la preparación de los conductos radiculares mediante rotación mecánica alternante existe desde mediados del siglo XX. El giro era horario y antihorario de 45 o 30 grados. También existían dispositivos mecánicos para efectuar movimientos lineales alternantes. Los resultados de la conformación de los conductos no fueron satisfactorios ya que se producía un notable transporte apical. Asimismo durante el año 2010 se han desarrollado instrumentos y motores para preparar los conductos radiculares con lo que se ha denominado preparación recíproca, principalmente rotatoria, pero también un instrumento y su motor produce un movimiento lineal recíproco. La preparación rotatoria recíproca ha ampliado el movimiento de giro antihorario a 120 grados y el horario a 60 grados. Para ello se han diseñado instrumentos o limas de níquel-titanio como Reciproc (VDW) o Wave One (Dentsply). En principio, cada conducto se prepara mediante un solo instrumento que avanza hacia apical impulsado por un movimiento de entrada y salida, como de piqueteo, previa creación de una vía de deslizamiento.
The present research refers to the type of bibliographic description, the same places as the object of study in the Comparative Study of single-root canal preparation with Titanium hand files (Greater Taper) and (Maillefer) in vital teeth. It is worth mentioning that the preparation of the root canals with alternating mechanical rotation there since the mid-twentieth century. The clockwise and counterclockwise rotation was 45 or 30 degrees. There were also mechanical devices for making linear movements alternating. The results of the formation of the ducts were not satisfactory because it produced a marked apical transport. Also during the year 2010 have been developed and other instruments to prepare root canals with what has been termed mutual preparation, mainly rotational, but also an instrument and its motor produces a reciprocal linear motion. The preparation has expanded reciprocal rotary motion turning clockwise to 120 degrees and hours at 60 degrees. This has been designed instruments and nickel-titanium as reciprocal (VDW) or Wave One (Dentsply). In principle, each conduit is prepared by a single instrument that moves apically driven by a movement in and out, like picketing, after creating a sliding track.
