Reliable apex location, whatever is in the canal

The DentaPort Root ZX is Morita’s established desktop apex locator. Morita put its case simply: the patented Quotient Method gives precise results irrespective of irrigation solution or blood in the root canal, shown on a large colour display with acoustic signals as the file approaches the apex.

The Root ZX is the benchmark apex locator – when a new locator comes to market, the Root ZX is the one it is usually compared with. The DentaPort Root ZX is Morita’s established desktop version of it.

This pack: Morita DentaPort Root ZX Apex Locator · 1 measuring cable (probe cord) · 5 contrary electrodes · 3 file holders · 1 test plug · 3 AA batteries

Key features

›  Precise, reliable measurement – Morita state it is unaffected by irrigant or blood in the canal.

›  Large colour display showing the file’s position as it advances.

›  Acoustic signals as the file reaches, or nears, the apex – so you can keep your eyes on the tooth.

›  No zero adjustment – always ready to use, with automatic calibration.

›  Weekly self-check with the test plug supplied: it plugs into the probe cord and the meter should read within 3 bars of the “1” mark.

Reading the display

The meter runs down towards the APEX mark as the file advances. Morita’s instructions use the 0.5 reading as the working-length reference, with the final working length a matter of clinical judgement for each canal.

Which Root ZX?

Before you use it

Morita’s instructions state the unit must not be used on a patient fitted with a pacemaker or ICD. The file holders and contrary electrodes are autoclavable up to 135 °C. The probe cord is approx. 1.6 m. The full instructions are linked below.

Frequently asked questions

How long do the batteries last?

Morita’s instructions give approximately 100 hours of use – roughly six to twelve months at a normal rate.

My probe cord has failed. Which one do I need?

The current cord for the DentaPort Root ZX is the Probe Cord Root ZX (MK2). Not sure? Call us with the unit and we will check it.

Is the Root ZX3 a replacement for this unit?

The Root ZX3 is Morita’s current generation, with a 40-bar real-time display on a smaller footprint. The DentaPort Root ZX remains a proven choice; the table above sets the two side by side.
