Success in endodontic treatment depends on various factors. One of the most important is appropriate preparation of the root canal system, in addition to keeping the periapical region intact as much as possible. This is achieved by determining the penetration depth of the instruments into the canal or the "working" length. Several methods are introduced for working-length determination. The most popular techniques are radiography and electronic apex locators. One type of apex locator is the Root ZX. The purpose of this study was to compare the accuracy of the Root ZX in vitro with conventional radiography.
牙髓治疗的成功取决于多种因素。其中最重要的因素之一是对根管系统进行适当的预备，同时尽可能保持根尖周区域的完整。这可以通过确定器械进入根管的深度即“工作”长度来实现。目前已引入多种确定工作长度的方法。最常用的技术是放射照相法和电子根尖定位仪。Root ZX是根尖定位仪的一种类型。本研究的目的是在体外比较Root ZX与传统放射照相法的准确性。
