Resumen
Podemos definir a la necrosis pulpar como la descomposición, séptica o no, del tejido conectivo pulpar que cursa con la destrucción del sistema microvascular y linfático, de las células y, en última instancia de las fibras nerviosas. Para el tratamiento de las necrosis pulpares podemos emplear el sistema protaper, este juego de limas consta de 6 instrumentos de aleación de níquel-titanio de conicidad variable; entre estos tenemos los shaping files, indicados para el modelado del conducto radicular, denominados SX, S1 y S2. El conjunto de instrumentos de acabado, finishing files, consta de 3 instrumentos denominados F1, F2 y F3 que se caracterizan por tener la parte activa con conicidad variable decreciente para permitir que corten más en la parte apical del conducto radicular. Como resultado de este trabajo las limas protaper han demostrado ser muy útiles gracias a su forma particular la cual va siendo más gruesa desde apical hacia coronal evitando la extrusión de bacterias del canal radicular hacia los tejidos periapicales y también se demostró que brinda una conicidad definida al conducto lo cual es esencial para una correcta obturación.
We can define pulp necrosis as decomposition, septic or not, pulp connective tissue that causes the destruction of microvascular and lymphatic system cells and ultimately nerve fibers. For the treatment of pulp necrosis we can use the ProTaper system, the file set comprises six instruments nickel-titanium alloy variable conicity; among these are the shaping files, suitable for modeling the root canal, called SX, S1 and S2. The instrument cluster finishing, finishing files, has 3 instruments denominated F1, F2 and F3 which are characterized by the active part variable taper downward to allow further cut in the apical part of the root canal. As a result of this work the files ProTaper have proved very useful thanks to its particular shape which will be thicker from apical to coronal preventing extrusion of bacteria in the root canal into the periapical tissues and provides the conduit defined taper which is essential for proper sealing.
