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」).

Are Kurds Refugees?

　 This article is not related to my usual dental practice. Recently, Kurds have been causing problems in Kawaguchi City, Saitama Prefecture, Japan. The Japanese mass media has not reported on this at all, but Japanese people who lived in Kawaguchi City have reported the situation vividly on Twitter. There is a growing sense of anxiety among the residents.  These Kurds have applied for refugee status in Japan, claiming that they are Turks, but they are persecuted in Turkey, so they have come to Japan as refugees and are asking for help. However, we know that they entered Japan as Turkish tourists and applied for refugee status as Kurds as soon as their tourist visas expired. By the way, about 600$ per month is provided from taxpayers' money as protection money. Generally, Japanese people do not discriminate against foreigners, but we do not like criminals who disrupt social security. The Japanese are equally averse to criminals, whether they are fellow countrymen or foreigners. I wo...

Murmur

 The thinking of the negative, that is not good for a good life. But, probably, at least I or you think following. It’s not that the past was good. Only in the past was there anything good. We have to grab the bright future. This is something that each of us living in the world can achieve if we work a little harder. The effort required to do so can be as little as 30 minutes of reading instead of 30 minutes of watching a smartphone or TV.

How to Connect NITI Files to EMR for Real-Time Monitoring.

In root canal treatment, the concept of working length is of great importance. The length from the apex to the reference point is defined by the dentist, and he or she proceeds with the file manipulation at that length. …working length, reference point, rubber-stopper, I hate those!  This is because it is likely to be an inaccurate operation.  I believe that the hidden reason why not a few dentists dislike root canal treatment is because of these "troublesome analog rules" on endodontics.  In particular, I did not feel confident in manipulating the NiTi file as per the working length, relying on the rubber-stopper, and I felt very uncomfortable. I have always been frustrated that I wish I could manipulate the NiTi file while measuring its length in real-time with the EMR, just like the hand SS files. To link the NiTi file to the EMR, the shortcut to a solution is to have the EMR clip grasped by the NiTi file. However, this would make the NiTi file extremely difficult to h...
