Irrigation of the root canal system is an essential step in the endodontic treatment. The aim of this article is to introduce continuous apical negative-pressure ultrasonic irrigation (CANUI), a new irrigation concept, and compare the characteristics of this new technique with current devices for activating the irrigant.
CANUI is designed for cleaning and disinfecting the root canal system. The device consists of a tube inside another tube that allows the continuous ultrasonic exchange of fresh irrigant, as the irrigant is simultaneously aspirated apically. The coronal and apical tubes are 0.75 and 0.3 mm in diameter, respectively. It is composed of a nickel-titanium microcannula suitable for the working length of curved canals.
The CANUI technique has the advantages of apical negative pressure (to avoid apical extrusion of the irrigant) and continuous ultrasonic irrigation (continuous refreshment of the irrigant and forced introduction into the canal ramifications).
The CANUI technique could improve the irrigation technique of dentists to reach more disinfection in endodontic treatments. Apical negative pressure, continuous ultrasonic irrigation, irrigation in curved canals, irrigation systems.
根管系统冲洗是牙髓病治疗中的一个重要步骤。本文旨在介绍一种新的冲洗概念——连续根尖负压超声冲洗（CANUI），并将这种新技术的特点与目前用于激活冲洗液的装置进行比较。
CANUI设计用于根管系统的清洁和消毒。该装置由一根置于另一根管内的管子组成，当冲洗液同时向根尖方向抽吸时，可实现新鲜冲洗液的连续超声交换。冠部管和根尖管的直径分别为0.75毫米和0.3毫米。它由一根适合弯曲根管工作长度的镍钛微套管组成。
CANUI技术具有根尖负压（避免冲洗液根尖挤出）和连续超声冲洗（冲洗液持续更新并强制进入根管分支）的优点。
CANUI技术可改善牙医的冲洗技术，在牙髓病治疗中实现更好的消毒效果。根尖负压、连续超声冲洗、弯曲根管冲洗、冲洗系统。
