Abstract
In an endodontic procedure, after the working of a root canal by instruments to remove 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 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 more round holes, a diagonal slit, or a U shaped slit, or any other shape. The vent opening should not extend more than approximately 0.75 mm from the closed spherical tip of the microcannula, it must be burr free and the opening must be smaller than the internal diameter of the microcannula.
