Resumen
El propósito del presente estudio Invitro fue evaluar la
preparación biomecánica entre el sistema rotatorio Pro_taper Vs
sistema oscilatorio EndoEze en primeros premolares inferiores y
comparar los resultados obtenidos por los dos métodos para
establecer su efecto sobre la anatomía original del mismo. El
estudio se realizo en 40 dientes unirradiculares para cuya
selección se tomaron radiografías preoperatoria dobles (VL_MD).
En los dientes seleccionados se les efectuó el corte de la corona, se
determino la longitud de trabajo externamente y a cuya longitud
se le resto 0.5 con una lima K #. 10. Se prepararon las muestras
en el cubo Kuttler para su respectivo corte por tercios, toma
fotográfica y preparación con los dos métodos de investigación.
Después de la instrumentación se tomaron nuevamente
fotografías, siguiendo los mismos criterios de padronización
adquiridos en la toma inicial. Las imágenes obtenidas fueron
llevadas al computador, posibilitando la medición de las áreas de
actuación de cada técnica y su respectivo análisis a través de un
programa específico para nuestro estudio Auto_Cad. Para
evaluar la acción de las técnicas de los diferentes grupos
experimentales, se medio el área del conducto radicular después
de la instrumentación, comparativamente al área inicial. Al
análisis óptico fotográfico podemos concluir que es evidente la
actuación de la técnica rotatoria ya que la marca que deja al
interior del conducto es circular, esto dio un aumento del área no
uniforme. La remoción de dentina hecha por el sistema oscilatorio
pareció más regular. A pesar de esto, no se puede observar
diferencia estadística entre las dos técnicas.
The purpose of the present studies Invitro it was to evaluate the preparation biomechanics among the rotational system Pro_taperVs oscillatory system Endo Eze in first inferior premolares and to compare the results obtained by the two methods to establish its effect on the original anatomy of the same one. The study one carries out in 40 teeth unirradiculares for whose selection took x-rays double (VL_MD) preoperatoria. In the selected teeth they were made the cut of the crown, you determines the work longitude externally and to whose longitude is subtracted 0.5 with a file K #. 10. They got ready the samples in the cube Kuttler for their respective court for thirds, he/she takes photographic and preparation with the two investigation methods. After the instrumentation they took pictures again, following the same approaches of acquired padronización in the initial taking. The obtained images were taken to the computer, facilitating the mensuration of the areas of performance of each technique and their respective analysis through a specific program for our study Auto_Cad. To evaluate the action of the techniques of the experimental different groups, you half the area of the conduit radicular after the instrumentation, comparatively to the initial area. To the optic photographic analysis we can conclude that it is evident the performance of the rotational technique since the mark that he/she leaves to the interior of the conduit is to circulate, this gave an increase of the area it doesn't standardize. The dentina removal made by the oscillatory system seemed more regular. In spite of this, one cannot observe difference statistic among the two techniques.
