Fragment removal

Posted on By Dr. Stefan Klinge In Endodontics

Dear members,

this is just a short video of an unusual fragment removal. When we talk about fragments, broken files...etc, we have always several techniques in mind. Whitch are ultrasonics, tube technique, instrument removal system (IRS) Maseran Kit and so on.

But in some cases it is only necessary to flush the file out with the help of ultrasonic.


Best regards

Dr. Stefan Klinge

Great short tip video Dr. Klinge! Thank you and looking forward to more!


Congratulations on your video post. What new techniques are you currently utilizing in endodontics to avoid these complications. Anything on the horizon?
many thanks

Thank you Dr. Salama for your kind reply.

As you certainly know there are many, many rotary file systems on the market. The fracture resistance has been improved by several modifications of the file design. But the major reason why files break is not able to be modified - the human who leads the file into the canal. :-)

The best way to avoid file breakage is to know the indication for rotary instruments. Severe curvatures or sudden curves are the best way to make a file break.
To much pressure, a wrong torque and a too high rotation speed are further reasons for breakage.

It's all about the glide path. When you always have in mind first to establish a sufficient glide path the the risk of a complication is much lower.
So in some cases you have to begin with an ISO 06 K-file and have to do many, many recapitulations before you can continue with ISO 08, 010 etc.
A glide path is established when a ( often prebended ) K-file ISO 15 or 20 reaches the apex without any major resistance. And then you can begin with rotating files to shape and clean.

A further very important issue is to have a straight access to the canal. If you don't have straight access the file is likely to break.

So you can see it's not only a technical issue but it is an issue of technique. :-)
