Nuove tecnologie per il miglioramento della disinfezione canalare

Abstract

ObjectivesThe aim of this study is to share with the reader the latest available technologies to improve the cleaning and debridement of the endodontic space and to give some hints to consider when integrating such new technologies into everyday clinical practice. Materials and methodsDifferent systems of mechanical activation of irrigants aimed at improving endodontic disinfection through a more effective removal of intracanal contents were analysed: manual mechanical agitation with gutta-percha cones, endodontic instruments or special brushes, vibrating systems, systems activated by low-speed handpieces or by sonic or subsonic energy, up to the use of laser to mechanically activate the irrigants and of apical negative pressure irrigation systems. Furthermore, systems aiming at improving the endocanalar bacterial decontamination through the use of chemicals were described, such as menozone, direct laser action, or light activated disinfection techniques Results and conclusionsThe ultrasonic activation of root canal irrigants and of sodium hypochlorite in particular still remains the gold standard by which all other systems of mechanical agitation analyzed in this dossier were judged.
