This in vitro study investigates the effect of cannula design on the amount of apically extruded sodium hypochlorite during non surgical root canal therapy. Ten human, extracted, single canal teeth were decoronated and instrumented and randomly assigned to two different treatment groups BO (blown out apices) and NBO (non-blown out apices). Three different cannula designs (Max-i-Probe, Pro-Rinse, Monoject) were compared in respect to the amount of extruded root canal irrigant yielded beyond the root apex. The results of this study support the conclusion that safe ended, side vented cannula design reduces the possibility of extruding sodium hypochlorite beyond the root apex.
