Abstract

The elimination of microorganisms from an infected root canal system is essential for a successful endodontic treatment. An incomplete removal of the intracanal medication contributes to the insufficient interfacial sealing and therefore has to be avoided. The aim of this study was to asses and compare three techniques to remove the medical insert and to quantify their efficiency. Six different irrigation protocols to remove the calcium hydroxide insert were tested: the apical master file, the Canal Brush and the passive ultrasonic agitation, each with 2 ml and 4 ml combined syringe of sodium hypochlorite and citric acid in intervals of 0.5 ml. None of the applied irrigation techniques was capable of removing the medical insert completely. The apical master file showed the worst cleaning achievement. The passive ultrasonic agitation with a combined irrigation achieves a good cleaning efficiency (94%) and can be recommended.

Key words:

calcium hydroxide removal, canalbrush technique, ultrasonic irrigation, intracanal medicament, irrigation, root canal treatment
