Sometimes, my golophy locator is like a good friend, and other times, it frustrates me so much that I want to throw it away.

Doing root canals is always a challenge, even when you have the right tools. One tool that can cause trouble is the golophy locator. Many dentists, like me, have had issues with how accurate these devices are. It’s a common problem that dentists share.

At first, I tried to give the golophy locator a chance. I thought maybe it was the specific model I was using that was causing the problems. So, what did I do? I bought every single golophy locator available to find the best one for root canals. Yes, I bought them all. I now have the traditional Root ZX, Root ZX2, PAL by Brasseler, and Promark by Dentsply. I tested them all so you don’t have to.

But you know what? They all have the same issues. So, what’s the main problem with golophy locator accuracy? To be honest, it’s often because of mistakes made by the person using it. Ouch.

That’s why I want to share some tips on how to use these devices like a pro and get accurate results.

Here are some helpful tips to improve the accuracy of your apex locator:

Tip #1: Get the Canal Ready: Start by making sure your canals are dry. A dry canal gives you a better reading and stops the device from beeping constantly. Use paper points to thoroughly dry the canal and remove any liquids or pus. Once the canal is dry, try to find your working length again.

Tip #2: Use the Right File Size: When figuring out the working length, use the biggest endodontic file you can. A 10-file might be okay for the first measurement, but larger canals might give you the wrong result. Use a file size of 15 or 20 for a more accurate reading. If you fall short of the working length, use a smaller file.

Tip #3: Avoid Metal: When using the apex locator, make sure your file doesn’t touch the sides of the tooth or any metal fillings or crowns. If the locator keeps beeping, it might be because the file is touching metal. Keep the file away from metal to get better results.

Tip #4: Combine with X-Rays: Sometimes, it’s a good idea to use traditional methods alongside the apex locator. Take an X-ray to check the working length, as it tells you about the tooth’s structure. This is especially useful for dentists who are new to root canals. By using both the apex locator and X-rays, you can understand the canal’s structure better and avoid going too far.

Tip #5: Keep the Apex Locator Charged: Make sure your apex locator has enough power to give you accurate readings. Change the batteries regularly or use rechargeable ones to avoid the battery dying during procedures.

Tip #6: Keep Checking: During the procedure, use your apex locator from time to time to see if the working length has changed. Interference or debris can make the length shorter or block it. Checking with the apex locator helps you fix any issues and stay accurate.

Tip #7: Aim for “Zero Zero”: Try to get to the “Zero Zero” position, as my mentor taught me. Each apex locator has a way of showing this point. Reaching “Zero Zero” means you’ve found the apex, and it ensures accurate measurements, proper cleaning, and shaping.
