Abstract

Embodiments of this disclosure provide a staging assembly (10) for negative pressure, multi-canal irrigation of a root canal system followed by obturation. The staging assembly may be part of a kit that includes a plurality of catheters (50) sized for insertion into the root canal system. To hold the catheter in its proper position in the canal, the catheter may include a stop (37) and the staging assembly may include a corresponding stop hold (36). The distal end (51) of the catheter can be positioned 2 mm to 5 mm from the terminus end of the root canal. The staging assembly is then sealed, creating a closed system. Irrigating solution is vacuum-drawn out the ends of the catheters and debris is evacuated through a vacuum port of the staging assembly. During irrigation, no hands on time is required by the clinician. After irrigation, vacuum is reversed to dry the canal. Obturation occurs through the vacuum port.
