Resumen
La gutapercha es el material de más frecuente uso en el paso de obturación del
conducto radicular. Este material termoplástico cumple con los principales
requisitos de un material de relleno del conducto radicular, uno de los cuales
está referido a ser un material de fácil remoción en casos de retratamiento
endodontico. Los métodos más usados para llevar a cabo la des-obturación
radicular son: mecánico, térmico, químico, o también una asociación de ellos,
aunque también puede ser usado el método a base de instrumentos especiales
como son los ultras sónicos. Los conos de gutapercha endodónticos están
compuestos de una resina vegetal, de la cual precisamente proviene su
nombre, estos conos pueden ser ablandados por solventes químicos.
Entre los solventes orgánicos que son usados con mayor frecuencia en
endodoncia tenemos: cloroformo, xylol, halotano, eucalyptol, turpentine, y
aceite de naranja. La gutapercha puede ser fácilmente removida con el uso de
un solvente orgánico con un instrumental calentado. Sin embargo, estas
sustancias parecen mostrar diferentes grados de éxito en la disolución y
remoción de la obturación de gutapercha presente en el conducto radicular.
El cloroformo y el xileno son dos solventes comúnmente usados, pero la us
food administration prohíbe el uso de cloroformo debido a su potencial
carcinogénico. Por el contrario, el xileno está disponible actualmente para uso
clínico, y no es considerado carcinogénico, aunque resulta ser muy tóxico para
los tejidos.
Los diferentes solventes han sido por mucho tiempo usados para desobturar el
conducto radicular. Sus propiedades deberían ser tomadas en consideración
con relación a su efectividad en la disolución del material de obturación
radicular.
Gutta-percha is the material most commonly used in the step of sealing root canal. This thermoplastic material meets the main requirements of a filling material from the root canal , one of which is referred to be a material easy removal in retreatment cases endodontic . Most methods used to carry out the de- sealing root are: mechanical, thermal, chemical , or even a combination of them, but can also be used the method using special instruments such as ultra sonic . Percha endodontic cones are compounds of a plant resin , which comes precisely its name, these cones can be softened by chemical solvents. Among the organic solvents that are used most often in endodontics are: chloroform, xylol , halothane , eucalyptol , turpentine , and Orange oil . The gutta percha can be easily removed with the use of an organic solvent with a heated instrument . However, these substances appear to show different degrees of success in the solution and removal of the gutta percha filling present in the root canal . Chloroform and xylene are two commonly used solvents , but the us food administration prohibits the use of chloroform because of its potential carcinogenic . By contrast , the xylene is currently available for use clinical , and is not considered carcinogenic , but proves to be extremely toxic to tissues . Different solvents have long been used for the desobturar root canal. Its properties should be taken into account with respect to their effectiveness in the dissolution of the sealing material root .
