Precautions to prevent damage to endodontic files

How should endodontic files be sterilized and stored?

1. First, rinse the used endodontic file with running water, and put it into the first and second trays of soaking liquid (2% glutaraldehyde). Soak for 10 hours.

2. Put the soaked Niti taper file into a shaker, soak for 15 minutes and then shake for 5 minutes. (The internal solution is a multi-enzyme cleaning agent, the main function is to remove dirt and decompose protein)

3. Put the pulp in the washing tank and wash away the residual liquid with running water.

4. Then put the small endodontic file into the high-pressure steam sodium collection box and sterilize it with a high-pressure steam oven for 45 minutes.

5. Finally, put the sterilized instruments into a sterile tray or cabinet in order of date. When the doctor uses it, the nurse removes it from the sterile tray or cabinet.

6. The used intraoral devices must undergo strict garbage classification and be destroyed.

Why does the endodontic file break?

1. Root canal anatomy factors. When encountering curved or calcified root canals, the pulp file may break. The way to avoid it is to be familiar with the anatomical characteristics of various pulp chambers, and take X-rays before surgery to get a preliminary understanding of the root canal.

2. Factors of improper operation, lack of effective root canal irrigation (NaOCl+EDTA recommended), incorrect instrument sequence, excessive instrument torque, etc. may cause the endodontic file to break.

3. As everyone knows the fatigue factor of endodontic files, new instruments are recommended for root canals that show stenosis, curvature or calcification on X-rays.

4. Improper use of endodontic files causes the elasticity of the instruments to decrease.

Precautions to prevent damage to endodontic files

1. Nowadays, for the benefit of many businesses, the quality of endodontic files is obviously not as good as before, so it is recommended to choose products from famous brands

2. A new endodontic file needs to be replaced after 10 times of routine use. If there are creases, bends, thinning threads, etc., please replace them at any time.

3. Some frequently used key endodontic files need to be replaced frequently, such as 20, 25, and 30. Small needles are more common for beginners.

4. High temperature and high pressure sterilization for those who have the conditions, but that is a test for endodontic files. Generally, the glutaraldehyde soaking method is commonly used in clinic

5. Using a microscope to check the cracks of a hand file is not the best policy

6. To understand the shape of the root canal, choose the appropriate size of the hand file, and be careful and pay attention, especially for the curved root canal

7. In the process of treatment, try not to artificially apply force, enter in compliance, and the rotation range should not be too large, otherwise it will easily break

8. For some large taper rotary files that are used many times, replace them in time

9. If it is unfortunate, like a broken needle in engine file, don’t be too nervous
