We Should Remind That the Importance of Root Canal Irrigation to Prevent Post-Endodontic Pain

Summary

I think that the cause of post endodontic pain after root canal treatment is the extrusion of debris, not the mechanical damage by the files at the periapical tissues. The debris, in this case, means, which caused during root canal preparation procedures, dentin chips, pulp tissue, microorganisms.
And I also think that it is very important that the irrigation of the root canal, especially in its apical third.



The post endodontic pain after endodontic treatment, of course, we don’t like it. It is because the patient will be in pain. 

Therefore, we are an effort to prevent occurring the post-endodontic pain after the root canal treatment.

Post endodontic pain after the root canal treatment usually occurs from apically extruded debris, not the mechanical damage by the files.



The debris stem from the root canal shaping procedure. In general, those were made of dentin chips, pulp tissue, microorganisms. If they extruded into periapical tissue, whatever the degree, we should assume that inflammation will occur. 

Thus I think that it is very important to irrigate the root canal to remove it routinely during root canal treatment.



Now, I will write about the specific technique of how I perform root canal irrigation at another time.

The above image is a great textbook on root canal irrigation written in Japanese (Chiro Kobayahi 「根管洗浄 よりよい治癒を目指して」).

The Sealer-Puff After the Root Canal Obturation, the Relationship Between Root Canal Irrigation

  The sealer-puff is a characteristic appearance of sealer overflow outside the apical foramen on the confirmatory dental photograph after root canal filling.  This is caused by a small amount of sealer overflowing outside the apical foramen when the dentists pressurize the area around the apical constriction to achieve a tight root canal filling. It is also caused by sealer penetrating the lateral branches of the apical-delta due to pressure at the apex. The sealer puff is, after all, an overflow of foreign material into the periapical tissue of the root apex. Of course, dentists must always try to prevent foreign material to overflow from the root apex into the apical periapical tissue. However, if we take into account the cause of sealer puffs, we can evaluate them from a different perspective. Sealer puffs are... The area around the root apex is properly cleaned and free of debris, ensuring the patency of the root canal. And Be caused by the application of a good flow of s...

The Agitation for Root Canal Irrigation

 An important aspect of root canal cleaning is just disinfection, especially at the root apex. This consists of removal of the smear layer of the dentinal wall and disinfection with sodium hypochlorite solution in the apical delta. Normally, dentists perform positive pressure irrigation using a syringe for root canal irrigation. They use saline solution, hydrogen peroxide solution, EDTA, or sodium hypochlorite solution as the cleaning solution. If the needle is thin enough to rinse deep into the root canal, dentists will usually feel that can clean the root canal. However, the reality is that the cleaning is not satisfactory. This is because only positive pressure irrigation makes it difficult to exert the chemical action of the irrigants. In particular, a narrow path such as the apical delta is difficult for the cleaning solution to reach. Therefore, it will be necessary to use some other method in addition to positive pressure washing. The agitation of root canal irrigation is. T...

Let's Consider Root Canal Irrigation

In my opinion, an extremely important step in root canal treatment is root canal irrigation. Cleaning the inside of the root canal is a more difficult procedure than the dentist may think and, in practice, often results in inadequate cleaning. Root canal irrigation is not as simple as simply placing fluid into the root canal. As the name "irrigation" implies, it is the act of physically and chemically removing the dirt inside the root canal using a cleaning solution - some kind of liquid. The root apex is the most important area of the root canal where cleaning is required.  In root canal treatment, aseptic preparation of the root canal by the dentist can prevent apical periodontitis. Once the root canal has been ideally enlarged with a NiTi file, it must then be thoroughly cleaned; if there is debris, it should be physically flushed out, and if there is inorganic or organic residue, it must be chemically cleaned. In addition, the root canal must be perforated and patency mus...
