Get Passive Ultrasonic Irrigation Of The Root Canal: A

Passive ultrasonic irrigation (PUI) is a noncutting irrigation protocol applied with ultrasonically activated files, and could be used with a continuous or intermittent flow of irrigant (5).

Since its introduction, US has become increasingly more useful in applications such as gaining access to canal openings, cleaning and shaping, obturation of root canals, removal of intracanal materials and obstructions, and endodontic surgery.

Ultrasonic devices This process involves the activation of a file with ultrasound which can then be used to both clean and shape the dentine of the root canal. Ultrasound instrumentation can be used either as a primary cleaning and shaping technique or after hand instrumentation.

After root canal preparation, it may be used as a last rinse to flush out any leftover chemical irrigant. The most common saline solution is 0.9 percent W/V normal saline [5]. Sodium hypochlorite (NaOCl) liquid, which is clear and light greenish-yellow, has a predominating chlorine smell.

Typically, a sonic device operates at 1-8 kHz and ultrasonic at 25-40 kHz.

The Soniclean Ultrasonic Irrigator is a state-of-the-art machine designed specifically to optimally clean cannulated surgical instruments, but can also clean non-cannulated surgical instruments, individually or simultaneously.

Apical vapor lock refers to air trapped within the root canal and often occurs in the apical third. The root is surrounded by bone, so the tip of the root canal forms a closed canal and air becomes trapped at the root during irrigation.

Passive Ultrasonic Irrigation (PUI) represents one of the most used systems to improve the endodontic irrigants activity. PUI acts increasing the reaction rate of NaOCl, with an increase of dentinal debris and smear layer removal. There is a stronger shear stress and a vapor lock reduction.
