Root ZX II by Morita is a 3rd generation electronic apex locator that was invented in 1992. It has grown to become the world's best selling apex locator, setting the industry for accuracy and patient safety. It was the first apex locator to be able to work in wet canals. The measurements made using Root ZX II are not affected by the presence of blood, electrolytes or other discharges. The patented technology incorporated into this device offers an accuracy rate of 97.5%. The display of the apex locator is user-friendly and large enough, making it easy to read. The apex locator exactly corresponds to the tactile sensation of using the file. Recordings from the meter displayed on the screen are virtually mirrored by the action of using actual files. The automatic calibration offered by this device allows real-time assessment of the location of the endodontic file inside the root canal. The additional features of the Root ZX II include no zero adjustment, battery power indication, and automatic power off function
An optional upgrade, The OTR Module, is available with the Root ZX II. The OTR Module enables the unit to function as a low-speed handpiece, an apex locator and as a combination of both. This makes it the perfect endodontic solution to carry out root canal procedures. The OTR Module snaps easily onto the unit and offers a unique 90-degree auto torque reverse and file advancement feature. It ensures excellent cutting efficiency with lesser stress on the rotary file, which reduces the chances of file separation and instrument fracture.
The use of Root ZX II is indicated in determination of the working length while carrying out endodontic treatment
The use of Root ZX II is contraindicated in patients with artificial pacemakers.
