Let’s talk Apex Locators. Do you know EXACTLY where you need your instrumentation to stop? Did you know that for every millimeter you’re off, you decrease your success rate? (Yikes!)
Here’s a really short Endo Quick Tip video on the ins and outs of your apex locator. The good news is that you can nail it every time! Click on the image for a quick, two-minute refresher.
After you watch the video, please let me know what you think in the blog comments! I really do enjoy hearing from you.

Hi, Dr Sanket here
Endodontist from mumbai..
As per literature there is no difference between 0.5 and 0.0 but for all practical purpose, keep rotaries till 0.5 ( recommend on root zx by their manual) but take hand files till 0.00..
This is what most recommend..
Taking rotaries till 0.0 often leads violation of AC..
Dr Riccuci recommends to stop till end of blue zone.
Kindly share your your email id.. I would be happy to share cases done till 0.5 with rotaries and 0.0 for handfiles in between
Hi Dr. Sanket, thanks for your comment. The apical constriction is a histological location, and so deriving the clinical significance for this can be an ambiguous location sometimes. I am a big believer in patency, and I have found that many cases don’t heal if your are not at 0.0. Hope this helps. -Sonia
Very clear explanation
I’m grateful this was helpful for you, Vivian! -Sonia
