Abstract

The incomplete removal of an intracanal medication may produce a leaking root canal filling. A lacking seal of the root canal filling results in bacterial reinfection, which might imply the failure in endodontic treatment. Accordingly, the effective removal of calcium hydroxide from the root canal system is of essential importance. The root canal is shaped with hand and rotary instruments under constant irrigation. Therefore, the aim of the present study was to investigate the influence of taper and different irrigation protocols on root canal cleanliness. Root canals prepared with the master apical file FlexMaster 40.06, К-rimers and H-files to final ISO-size 40, Reciproc rotary files to preparation size 40 and final taper 0.06 and 0.04 respectively. None of the applied irrigation techniques was able to remove the calcium hydroxide completely. Best results in vitro can be achieved with the master apical file FlexMaster 40.06 and irrigation volume of 8 ml sodium hypochlorite (NaOCl) and the citric acid solutions with sequences of 0.5 ml, which justifies a clinical recommendation.

Key words:
