Dental Negative Pressure Irrigation System

Negative Pressure Irrigation is an effective endodontic irrigation system. Instead of applying positive pressure, we uses suction to pull irrigant down the root canal, and then up and away into the Hi-Vac suction unit. It is called  “negative apical pressure,” .Endodontic irrigation involved filling a syringe with sodium hypochlorite, carefully putting it into the canal and then cautiously injecting with positive pressure. There are accounts of hypochlorite accidents occurring that can cause severe tissue damage
