Ocena porównawcza dynamicznych i biernych systemów przepłukiwania kanału korzeniowego w aspekcie skuteczności oczyszczania kanału oraz ryzyka przepchnięcia środka płuczącego poza wierzchołek kanału
The EndoVac (Discus Dental, Culver City, CA) irrigation system, with its apical negative pressure, is able to thoroughly remove the micro debris at the apical constricture, thereby providing a better environment to be filled with sealer [1, 11], without forcing the solution out of the apex into the periapical tissue. The system utilises apical negative pressure through the high-volume evacuation system, permitting a thorough irrigation with a high volume of irrigation solution [12, 13]. Nielsen and Craig Baumgartner [14] found that the volume of irrigant delivered with the EndoVac system was significantly more than the volume delivered with needle irrigation over the same amount of time. Furthermore, they reported significantly better debridement for the EndoVac system compared to needle irrigation.
Root canal irrigation carries a risk of extrusion of irrigant into the periapical tissues which can be associated with pain, swelling, and tissue damage [15, 16]. Studies have shown less extrusion with sonic or apical negative pressure devices compared with syringe and side-port needle or passive ultrasonic irrigation with continuous irrigant flow [3, 17].
Thisin vitrostudy was aimed to evaluate the efficacy of apical cleaning and the extent of extruded irrigating solution using the EndoVac irrigation system compared to the tip-vented and side-vented root canal irrigating systems.
Methods
The study was approved by the College of Dentistry Research Centre (CDRC), King Saud [...]
