Endovac

The EndoVac is a new irrigation system. A delivery/evacuation tip is attached to a syringe of irrigant and the high speed suction of the dental chair . A small tube attaches either a macro- or microcannula to the suction. The delivery/evacuation tip places irrigant in the chamber and siphons off the excess to prevent overflow. The macrocannula is plastic with an open end that measures International Standards Organization (ISO) size 55 with a .02 taper. The microcannula is stainless steel and has 12 small, laterally positioned, offset holes in 4 rows of 3, with a closed end measuring ISO size 32 . As these cannulas are placed in the canal, negative pressure pulls irrigant from a fresh supply in the chamber, down the canal to the tip of the cannula, into the cannula, and out through the suction hose.
