Introduction The purpose of this in vitro study was to compare the debris removal effectiveness of EndoActivator, EndoUltra, PiezoFlow, Cavitron PEC Insert, EndoVac, and Maxi-Probe in human mandibular molars after instrumentation. Methods The mesial roots of 60 extracted mandibular molars were mounted in resin by using the K-Kube and then sectioned at 2 and 4 mm from the apex. The specimens were instrumented to size 40.04 using a standard irrigation protocol. Specimens were randomly assigned to one of six adjunct irrigation treatment groups, disassembled for imaging and then reassembled prior to adjunct irrigation. Adjunct irrigation was accomplished according to manufacturers recommendations. Specimens were again disassembled and imaged. The percentage of cleanliness for each canal and isthmus both before and following adjunct irrigation was calculated by using interactive software. Comparisons of canal and isthmuscleanliness before and after adjunct irrigation were made using paired t tests, and the groups were compared with repeated-measures analysis of variance P .05. Results The Cavitron PEC Insert performed significantly better than all the other adjunct devices with the exception of the EndoUltra. There were no statistically significant differences in canal and isthmus cleanliness at 2 and 4 mm from working length. Conclusions Final irrigation using the Cavitron PEC Insert significantly improves canal and isthmus cleanliness compared to EndoActivator, PiezoFlow, EndoVac, and Max-i-Probe needle irrigation.
