The scope of application of endodontic files

1.What is an endodontic file?

In dental treatment, root canal therapy is the preferred method for the treatment of pulp and periapical diseases. This can completely remove the inflammatory pulp and necrotic substances in the root canal, expand the root canal, properly disinfect the root canal, and finally fill the root canal tightly to remove the harmful stimulation of infectious substances in the root canal to the tissues around the apex of the root canal and prevent Periapical lesions occur or promote healing of periapical lesions. For mechanical cleaning and irrigation of the root canal system, an endodontic file is required. Therefore, the endodontic file is a file tool for mechanical cleaning.

2.The scope of application of endodontic files

There are many types of endodontic files. If they are classified according to the driving method, they can be divided into hand files and engine files. If classified according to device taper, it can be divided into standard taper devices and non-standard taper devices. And according to the material classification, it can be divided into stainless steel and nickel titanium alloy. The following will specifically introduce some endodontic files and their scope of application.

(1) K file, its material is stainless steel, the cross section is square, the cutting force is weak, and the sharpness of the tip is relatively weak. Due to its weak penetration and cutting force, the K file is generally used to repair root canals and apical holes. Its use method is to use the balance force method to rotate and lift as much as possible, and do not apply excessive force downward. Therefore, when using the K file, we must pay special attention to the pre-bending in advance, the method is gentle, to avoid applying downward pressure,

(2) H file, its material is stainless steel, the cross section is round, the cutting ability is strong, and the sharpness of the tip is strong. The cutting ability of the H file is extremely strong, so it is generally used for lifting up and down. The method of using the H file is: up and down cutting, as much as possible without rotating. At the same time, its blade is relatively sharp, so do not continuously pull in one direction, otherwise it will be easy to over-cut, and it should be as gentle as possible when rotating, do not violently pull when encountering resistance, and should not be used for root canals with large curvature. .

(3)Reciproc file, its material is also stainless steel, the cross section is triangular, the cutting force is good, the sharpness of the tip is strong, and the passability is good. Reciproc file is mainly used for the exploration of small root canal of calcification of posterior teeth. In the process of using, you need to pre-bend in advance, the method is gentle and stable, to avoid the tip hit the wall.

In fact, there are many types of endodontic files, such as Pro-flexi file, Niti Protaper Gold heat-activated, UFile, etc. They all have their own characteristics and scope of application, which can help dentists in root canal treatment.
