Housed in a new, sleek design, Root ZX3 offers automatic calibration and features an overall smaller footprint, yet a larger, high-contrast display screen. Its trusted technology, based on impedance measurement, has been independently evaluated to be 97.5% accurate and can be used in wet or dry canals. As an optional upgrade, the new HF Module offers an updated approach for canal treatment by utilizing high-frequency conduction (HFC). It can be used as an adjunct to root-canal therapy with several other applications.
