Resumen
distintos fenómenos que se producen durante la aplicación de éste dentro del conducto radicular. Estos fenómenos: oscilación, cavitación, microcorriente acústica y generación de calor, van a producir efectos sobre la estructuras dentarias, especialmente sobre la dentina y la capa de barrillo dentinario, así como la potenciación de efectos antimicrobianos al utilizarse en combinación con soluciones irrigantes. El uso del ultrasonido en la terapéutica endodóncica abarca desde la eliminación de restauraciones para acceder al sistema de conductos, eliminación de obstrucciones como instrumentos fracturados y calcificaciones, la preparación biomecánica, irrigación ultrasónica y obturación del sistema de conductos, así como en la cirugía endodóntica. La presente revisión de literatura permitió Describir la utilización de sistema ultrasónico para retirar instrumentos fracturados en raíces distales de molares inferiores, Identificar, los factores que influyen en la remoción de instrumentos fracturados. Así como definir, las técnicas para el retiro de instrumentos fracturados, lo que nos permitió especificar, los efectos de la aplicación del ultrasonido en el conducto radicular en las conclusiones y recomendar, las precauciones en el empleo de instrumental sónico y ultrasónico en la preparación del sistema de conductos, ya que si no se tiene control de su acción en la zona apical, puede producir desgaste excesivo y perforaciones, con consecuencias graves
The use of ultrasound in endodontics, is based on the different phenomena that occur during the application of it into the root canal. These phenomena oscillation, cavitation, acoustic microcurrent and heat generation, will produce effects on tooth structure, especially on the dentin and smear layer, as well as enhancement of antimicrobial effects when used in combination with irrigating solutions. The use of ultrasound in endodontic therapy ranges from removal of restorations to enter the duct system, removal of obstructions such as broken instruments and calcifications, biomechanical preparation, irrigation and ultrasonic sealing the duct system as well as endodontic surgery. This literature review was to describe the use of ultrasonic instruments to remove fractured in distal roots of lower molars, identify the factors that influence the removal of fractured instruments. And define the techniques for removal of fractured instruments, not allowing us to specify the effects of ultrasound application in the root canal on the findings and recommend precautions in the use of sonic and ultrasonic instruments in the preparation of duct system, because if you do not have control of their action in the apical area, can cause excessive wear and punctures, with serious consequences.
