Top 7 Apex Locator Comparison

Apex Locator – Root Canal Finder

Successful root canal therapy requires accurate location of the apical foramen. An apex locator is used in conjunction with radiography, in many cases, as an additional measure to ensure proper determination of canal length.

Apex Locator Purchase – Things To Consider

apex locatorThe modern apex locator is a small, light weight unit which typically operates off batteries when necessary to increase portability. They all have some form of display to indicate the approximate distance of the file tip to the apex, and to show when the apical foramen is reached. Many have audible alarms which can be set to the operators preference for an additional indication to ensure accuracy of measurement.

Apex Locator Autoclavable Components

Components coming into contact with the patient are typically lip clips (or electrodes), and file clips (or holders). These items can be expected to wear out over time, especially with autoclave requirements, and are available for purchase through the manufacturers. The cost (when available) of these items is included in the apex locator comparison below, as this should be considered prior to purchase. The table is a good comparison of some of the top selling apex locator units we have looked at, but does not include all of the excellent units available.

Morita Root ZX Mini

morita root zx miniAs computer micro chip technology gets more and more compact, so goes the apex locator. The Morita Root ZX mini is a super compact design containing the same technology that made the Morita Root ZX II the number one seller.

Morita Root ZX Mini – Picture Says It All

The fact that it measures just over 4″ by 2″ makes the 97.5% accuracy rate of the Morita Root ZX Mini interesting. The weight of 3.88 ounces makes it hard to overlook. LCD technology makes this possible, while still providing a screen capable of viewing from a distance. The Mini also offers 3 programmable memory settings, can withstand a pretty good drop, calibrates itself, and turns itself off to save battery power.morita root zx mini image

Morita Root ZX Mini – Accurate Measurement

Utilizing its own version of the ratio technique, Morita Root ZX mini provides accurate indication of file location. Accuracy is not affected by the presence or absence of blood, electrolytes, saline, tap water, or hydrogen peroxide.
Also, unit does not require zeroing before measuring each individual canal. Flash bar and memory bar available to be set as guides for canal measurement and enlargement. Flash bar can be set anywhere between 2 and APEX. Memory bar is used as a guide when file size is changed for canal enlargement.

Apex Locators: Another Piece To The Puzzle

Apex Locators – Insight


Added insight from a tool you will use to help ensure a successful procedure. Apex Locators are a must have for the modern endodontic practice.

Apex Locators – How They Work

Apex Locators use an electrical circuit, with a pain-free current traveling through the root canal, actually using the patients oral tissues as a conductive flow path.

To achieve this circuit, a lead is attached to a file, which in turn, is placed into the root canal. Another lead is attached to the patients lip to complete the setup. Since hard tooth structure is a poor conductor, the signal at initial setup, will be very weak at best. As file is advanced through this area to the patients apical foramen, the signal becomes very strong due to the electricalapex locators conductivity of these tissues. Signal is transmitted to the operator via the consoles LCD screen and typically an audible alarm.

Apex Locator Technology – Just How Accurate Is It?

Studies show that electronic apex location technology is very sound, accurate, and when used in conjunction with a good radiograph, provides the best feedback available for determining apical foramen location. The key is the ability of newer apex locators to perform accurately in varying degrees of viscous fluids. Earlier models showed difficulty measuring distance accurately when files were immersed in fluids containing a high degree of blood. All newer models have greatly overcome this impediment, of course, some a little better than others. In the hands of capable operators, modern apex locators provide time saving information for more efficient case treatments.

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 providing dentists the capability to work in wet canals. Blood and other fluids do not typically affect measurements.

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 Root ZX II Features

  • 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.

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
