The FIND apex locator is a battery-operated portable device designed to locate the foramen and determine the working length during root canal treatments. Using a multifrequency-dependent impedance method and a series of proprietary algorithms, the FIND apex locator accurately determines the position of the anatomical apical foramen.
Utilizing the advantages of its well-proven technology, the FIND apex locator offers the clinician unsurpassed accuracy, unrivaled reliability, and an extremely user-friendly interface. The custom color graphic display of the unit helps to achieve the optimal endodontic performance required during every root canal treatment.
- Convenient, easy-to-read display has unsurpassed accuracy1
- Multifrequency measurements are fully automatic
- Compact design with small footprint fits easily on a counter or treatment tray
Indications for Use
The Endo-Eze FIND apex locator is an electronic device used for apex localization and working-length determination during root canal treatment. It is indicated for patients who need to undergo root canal treatment, which requires precise determination of position of the dental file in the canal relative to the root apex. FIND apex locator should be used only in hospital environments, clinics, or dental offices by qualified dental personnel.
Unsurpassed Accuracy and ReliabilityThe most widely used method for determining the apical limit is the radiograph, but, unfortunately, it’s not the most accurate. If the film isn’t positioned exactly, if the angle of the x-ray beam isn’t precise, if there are interferences from equipment or anatomical structures, the reliability of the radiograph suffers. Not to mention that the location of the apical foramen is not always the same as the radiographical apex to begin with. By sending an electronic signal all the way to the tip of the file, the FIND apex locator lets you know when you've reached the apical foramen, eliminating the risk of overinstrumentation beyond the apex into the periapical tissues.
Increased SuccessClinical research shows that establishing the correct working length is critical for success in root canal therapy.2,3 Using an apex locator in combination with radiographic measurements can significantly increase your success rate in the endodontic treatments you provide.
Compact and PortableMeasuring approximately 3.6 inches x 2.2 inches, the FIND apex locator is small enough to easily fit on a treatment tray. Its compact, portable design also makes it extremely easy to move from operatory to operatory.
Advanced, Proprietary TechnologyDrawing on the research of Dr. Carols Ramos, an expert in apex location, the FIND apex locator uses a multifrequency-dependent impedance method and proprietary algorithms to determine the position of the apical foramen. These methods have been tested again and again to provide accurate, reliable results with any RCT.
User-Friendly DesignThe FIND apex locator features intuitive controls and full-color graphics to make it extremely easy to read. It also combines audio alerts so you can monitor the file progression even when you’re not looking at the device.
Battery OperatedThe FIND apex locator operates on a single, standard AAA battery, so you don’t have to worry about expensive, hard-to-find replacements.

How accurate and reliable is the FIND apex locator when compared to more established brands?
The Endo-Eze FIND apex locator is based on a patented, multifrequency-based technology, making the accuracy unsurpassed.
How complicated is it to operate? Do I have to calibrate the device and perform other technical tasks to operate it?
The FIND apex locator is easy to use and does not need calibration. It provides quick feedback to assure that the multifrequency is operating properly.
How is it powered, and does it need an expensive customized battery?
The FIND apex locator utilizes a standard AAA battery.
How can an apex locator improve my practice?
Utilizing an accurate and reliable apex locator will result in accurate working length measurements, leading to reduced complications like apical perforations.
How accurate and reliable is an apex locator?
Studies have shown that multifrequency-based apex locators locate the apical foramen with 95–98% accuracy.
How accurate is an apex locator when compared to X-rays?
Traditionally, radiography has been the most used method in obtaining information on the anatomy of the root canal and its surrounding tissues. However, the working length measurement performed radiographically presents several limitations, namely radiation exposure, time expenditure, and difficulty of interpretation because it is a two-dimensional image that is often overlapped with anatomic structures and is subject to the interpretation of the observer. These limitations contribute to the low 25–40% accuracy of X-rays when locating the apical foramen.4
How much does an apex locator typically cost?
Typically apex locators cost less than $1,000.
Will an apex locator make my practice better?
A quality apex locator will save you time and money by helping you easily and accurately determine the proper working length, which mitigates complications and reduces the number of retreatments you experience. “Undoubtedly, over-instrumentation reduces the success rate of endodontic treatment.”5
Is an apex locator really necessary? Aren’t radiographs accurate enough?
Using an apex locator—rather than a radiograph alone—can greatly minimize the risk of overinstrumentation. Research has shown that even with an acceptable radiographic working length, instrumentation beyond the apical foramen is a widespread problem, occurring in over half (51%) of the premolars and nearly a quarter (22%) of the molars evaluated in a recent study.3
How does the FIND apex locator compare to other apex locators?
There are many things the FIND apex locator offers that other apex locators don’t. The first thing you’ll notice about the FIND apex locator is its size. It’s small, compact, and portable. In addition, its screen is full color and easy to read.
How big is the FIND apex locator?
It’s 92mm x 55mm with a 51mm x 38mm screen.
What if I forget to turn the unit off?
The FIND apex locator will automatically shut down after five minutes without use.
Can I use the device even if it’s not sitting in its cradle?
Yes. The FIND apex locator can be used either in or out of its cradle.
