When it comes to irrigating root canals, Pac-Dent’s iVac Irrigation System offers 3 distinct advantages based on years of endodontic research and science for root canal irrigation and disinfection.
The first is the use of ultrasonic vibration, which acts as a chemical catalyst for the irrigating solutions. This, paired with the transient cavitation and microstreaming effects, helps guide the chemical-mechanical cleaning action in difficult-to-access canal spaces.
Second, negative pressure is used to help move the irrigation fluid from the pulp chamber to the apical limit without extruding beyond the foramen.
Lastly, the system is based on concomitant irrigation, a principle in which the volume of irrigating liquid is renewed continuously. This constant fluid replacement helps stimulate chemical activity by depositing the solution without breaks.
“Ultrasonic activation, negative pressure, and concomitant irrigation are the 3 most significant concepts established by endodontic science for root canal disinfection,” noted Dr. Carlos Spironelli Ramos, an endodontic researcher and lecturer for over 25 years. “The iVac system unites these 3 concepts in a single device, while avoiding the risk of liquid extrusion into the periapical tissue and activating the renewed fluid inside the canal.”
Filling the Gap
The arrival of NiTi engine-driven file systems and mechanized instrumentation systems has inarguably been a boon to root canal therapy, allowing canal instrumentation to become faster and more predictable compared with manual techniques. But these developments also have created a gap between quicker preparation and proper infection control.
“The iVac system has been designed to compensate for the time disinfection solutions should remain in the canal—filling the gap left behind by instrumentation development,” said Dr. Spironelli Ramos. “It safely hands over a high volume of irrigant in the apical third of the canal, while also activating the liquid with ultrasonic vibration.”
Versatile Uses
Simple to install, the iVac ultrasonic connector is designed to easily hold the aspiration/activation cannula and deliver the irrigating liquid properly while transmitting the vibration from the piezo ultra-sonic handpiece. Additionally, tubes and connections allow the ordinary vacuum outlet to be coupled, adding negative pressure to the system.
The iVac system is an invaluable irrigation solution in periapical lesions where there is resorption of the apical foramen, apexification and apexogenesis, and when there is a close position between the root apex and the maxillary sinus or mandibular canal.
