There have been many advancements in the mechanical preparation of root canals. Although vastly improved, endodontic success has been limited due to ineffective disinfection of the apical third.

Current clinical studies performed on closed root canal systems under a microscope show the formation of static bubble or vapor lock at the apex of the canal.

ASI’s Root Down Negative Pressure IrriVac™ system simultaneously delivers fresh irrigant while adequately evacuating debris at the apex using a single handpiece to safely remove the vapor lock.

ASI’s Root Down Negative Pressure IrriVac™ is a wand style titanium handpiece that accepts all standard luer type needles and delivers any common irrigant solutions with a finger-friendly push-button. Irrigant is dispensed at the coronal access through a piece of tubing over the needle and pulled into the canal. ASI’s new disposable iNP™ Negative Pressure Needle, used with ASI’s Root Down Negative Pressure IrriVac™ achieves full working length, maintains aspiration and adequately evacuates debris from the canal.

The tapered shape tip of the iNP™ needle has an inner diameter of 0.26 and an outer diameter of .36 for insertion into the apical end while still allowing adequate irrigant flow alongside the needle. The iNP™ needle’s inside diameter beyond the tapered shape is .50 ID and .65 OD to maintain aspiration and adequately remove debris.

Essentially the iNP™ needle has the reach of a 30 gauge needle and a flow rate of a 22 gauge needle. Both characteristics make possible irrigant flow to the apical region and adequate debris removal from the canal.
