Importancia de la activación de la irrigación durante el tratamiento de conductosuna revisión de la literatura

Resumen

The complex anatomy of root canal systems has limited our ability to clean and disinfect it predictably. The removal of any vital and necrotic pulp tissue, microorganisms and their toxins, along with the smear layer is essential for endodontic success. Proper cleaning of the canal system is a necessary goal for endodontic treatment success, and so has been the subject of numerous studies. Recently, new irrigation techniques have been developed, which use mechanical systems in order to improve the manual technique and to help the irrigant get to the most intricated areas of the canal system. This study will review the literature about two important mechanical irrigation techniques: sonic and ultrasonic irrigation, in order to check its effectiveness over the conventional technique, and to compare them. Both techniques have been proven to be more efficient than the traditional one. however, the use of ultrasonics has been more successful in removing debris from the duct, distributing irrigant and penetrating uninstrumented areas compared to sonic activation.
