There are many different types of endodontic files that can be used for endodontic eradication, root canal preparation and filling, so how do we choose the correct endodontic file? What is the difference between different endodontic files?

Today, endodontic files have better materials, improved file design and more user-friendly technology, but there are still cases of endodontic file breaks during root canal treatment. So, what should be done when the endodontic file is damaged?

The R-shaped file, called rat tail file, is characterized in that the blade is not continuous, but has inverted tooth-like protrusions. This inverted tooth is also hovering around the long axis. The R file has a very sharp blade and a high cutting efficiency. But the filed wall is not smooth. The root canal file is often used i
