Root ZX II – Humble Beginnings
Even though the technology has been around for some time, it’s application to the dental industry is fairly recent. As with any new technique, or technology, acceptance was a little slow early on. Invented in 1992, the J. Morita Root ZX II is currently one of the best selling apex locators. It has proven itself safe and accurate, and was the first unit to provide dentists the capability to work in wet canals. Even though it’s recommended to maintain the area as dry as possible, blood and other fluids do not typically affect measurements.
Root ZX II – Patented Technology
Root ZX II patented technology offers an accuracy rate above 96%. LCD readout is large and easy to read. Action of the meter in the display corresponds to the tactile sensation of using the file.
Other features include:
- slim, lightweight file holder
- no zero-adjustment
- automatic calibration
- battery power indication
- automatic power off function.
As an optional upgrade, a module enables the unit to function as a low speed handpiece, apex locator, or a combination of both. The module snaps easily onto the back of the unit and offers numerous safety features including Auto Torque Slow Down. Also see Tri-Auto ZX for a cordless model from J. Morita.
An in vitro comparison of three apex locators concluded that the Root ZX II was significantly more accurate at finding the apical foramen than competitive models. See the following: In Vitro Comparison then come back here for the best price on the J. Morita Root ZX II.
