What can endodontic file do?

With the development of dental technology, more and more endodontic files are used in dental treatment. Especially when you need root canal treatment or dental pulp treatment, you need to use various endodontic files. So, what is the function of the endodontic file? This article will introduce you in detail.

When do you need an endodontic files?

Function of Endodontic file


1.When do you need endodontic files?

In general, if you have an infection in the pulp or root tissue, you need to go to the dentist for treatment. And when the dentist is treating you with pulp, there is a key step is to perform mechanical cleaning and irrigation of the root canal system. This is to clean up the residue on the channel wall, and in this process, you will need to use a variety of stainless steel or nickel-titanium alloy files, such as Niti Protaper Gold heat-activated, Niti taper file, etc. This can make cleaning more thorough. Looking back at the history of dental pulp treatment, we will find that dental pulp treatment has been on the road of development since the 19th century. Through continuous exploration and discovery, dentists and scientists around the world have found ways to treat dental pulp infections and preserve teeth at the same time. Then you need to use a file for mechanical cleaning.

 

2. Function of Endodontic file

In fact, endodontic files include hand files and engine file, and the following will focus on the functions of hand files. In general, there are two basic working methods for hand root canal preparation instruments, namely, expansion and file.

(1) Expansion type: By rotating the root canal file, the rotating instrument cuts the root canal wall and drills deep into the root canal. When the instrument rotates clockwise, the debris in the root canal moves along the thread of the instrument toward the root canal. Therefore, the expansion type is beneficial to remove debris in the root canal. However, due to the fact that the expansion type can easily cause the device to break, when the hand file is used clinically, the combination of the expansion type and the file type is often used. For example, turn the instrument clockwise (<90° angle) to make the edge of the instrument cut into the wall of the human dentin, then loosen it, and then pull the instrument back toward the root canal to cut off the dentin that has been "bitten" by the edge of the instrument. Repeat the above actions until the instrument reaches the working length. Switch to the No. 1 instrument and complete the root canal preparation in this way.

(2) File type: such as H file and K file, they use a thin root canal file that can reach the working length to insert the root canal to the working length, then pull the instrument against the root canal wall, and cut the dentin wall during the pulling process, which does not include rotating instruments action. Repeat the above actions multiple times in all directions of the root canal wall until the root canal has been enlarged to a certain root canal file can reach the working length without resistance. Prepare by number. The file method is safe, and it is not easy to break the instrument. However, the linear motion of the root canal instrument being pushed and pulled in the root canal is similar to the movement of the piston in the cylinder, and it is easy to push the dentin debris under the file and the infectious substances in the root canal to the direction of the apex, which is easy to occur The root canal of the apex is blocked or debris and infectious substances are pushed out of the apical hole.

(3) Gates Drill is used to initially expand the root canal opening and open the root canal crown in the root canal, so that subsequent instruments and irrigation fluid can easily enter the root canal. When using a reamer, carefully insert the tip of the drill into the root canal opening and carefully pull along the outer edge and side wall of the root canal opening. Do not use violence, otherwise it is easy to break the equipment, or form steps and side penetration. The depth of entry is limited to the straight part of the root canal and cannot enter the curved part. When raised, the instrument should be in a rotating state to prevent it from being stuck and broken. When using a large size, the root canal wall may be too thin, especially at the root branch of the mesial root of the molar.

 

With the progress of the times, the entire endodontic dentistry is also making continuous progress. In particular, endodontic files of various materials and uses allow dentists to bring us better dental treatment.
