To improve a method and apparatus in the field of endodontics, particularly used during root canal procedures.

In the method in an endodontic procedure, after the working of a root canal by instruments to remove a material and shape the walls of the canal, irrigant is supplied via a microcannula. A vacuum is applied via a tube which is inserted partway down the root canal. The tube and microcannula pass through a material created by a standard dental filling material of a nature which provides a seal at a position near the top of the coronal opening. The irrigant is supplied in a manner sufficient to ensure delivery to a side vent of the microcannula. The vacuum at the end of tube draws the irrigant and debris up from the apex of the root canal into the tube. The side vent may have a plurality of round holes, a diagonal slit or a U-shaped slit, or any other shape.
