Root Canal Treatment & Medicines 9'17"

In Japan, a root canal treatment is most commonly done by a general dentist and not a specialist.
The intent of a root canal is , of course, to remove the inflamed pulp
treat the root canal with medication to kill the bacteria, and ready it for further treatment.
Therefore, we need to open the infected tooth with a reamer or file and remove the damaged pulp.
Afterwards, we apply a variety of medications with anti-bacterial properties.
But do we really need to use all these medications, and if so, how do we apply them properly?
Let’s start by examining how a root canal really looks.
Here is a specimen of a root canal. It seems like a complex labyrinth of pathways spreading in many directions at once.
This is an important idea to remember when we further discuss the use of root canal medicines
Root Canal Treatment and Medicines
Here we can take a look at a model made from the root
which was cleaned out with a file.We used an extracted tooth,
cleaned it with a file and put a silicone impression material into it.
After it set hard, it was submerged into a solution.
After 24 hours, the tooth was dissolved and only the model of the root remained
Then it was plated with palladium.
We now examine it through a scanning electron Microscope.
We can now see the exact outline of the root.
The root is shaped so complicated and the file can only reach a part of the root.
When we perform a cross section of the root, we can notice that it has many small channels that a file could never reach.
Therefore the question remains. How could we reach those tiny roots?
Prof Asai says, “As you can see so far, the root of a tooth has many more canals than we realized,
and that we could never reach by doing a normal root canal treatment. No reamer files would have access to those areas.
For this reason, we need to try a different approach to access these tiny canal
not only physically but also chemically to kill the bacteria that remains within them.
We start with Neo Cleaner which is a sodium hypochlorite solution that will kill bacteria and soothe infected tissues.
After this we apply different root canal medications to complete the cleaning and anti-bacterial treatment of the root canal.
Each medication has its’own benefit which I will discuss shortly.
It is obvious that we need root canal medications to get the infected area as bacteria free as possible.
Even when I access the root canal physically more than five times I cannot clean it completely.
I apply the NEO cleaner to the canal after I open it with a file then could clean it.
with a file then could clean it in 2.5-times with FG NEO
Using NaOCl, 1.8-times,
FG-Neo + NaOCl I could do in 1.4-times.
Now I want to find out how this solution actually works within the root canal tissues.
I submerge some pulp tissue into it, and I can see that it dissolves quickly.
This shows me what actually happens in the canals when I flush them with the NeoCleaner10% sodium hypochlorite
Neo Cleaner contains 10% Sodium Hypochlorite.
Neo Cleaner is not only a disinfectant but also has been known to be able to kill viruses.
For a closer look I can show you how the Neo Cleaner works in the canals by using an electron microscope to visualize the pulp.
There I see pre-dentin tissues between the pulp and dentin which have small amounts of calcifications.
While doing a pulpotomy or pulpectomy, they only remove the pulp leaving pre-dentin which has many vital tissues.
This shows us the surface of pre-dentin consisting of collagen meshes.
You can see the surface of the dentin and its’ calcifications.
Applying Neo Cleaner, remove vital tissues.
These pictures show the surface of the canal walls after treatment with Neo cleaner.
NaOCl also has a strong power to kill viruses. Neo Cleaner is a disinfectant in the canal.
In the next discussion we will show how root canal medications can achieve further disinfection.
A root canal medication has to be able to disinfect, heal lesions, and ease the pain of an infection.
Each type of medication has its own characteristics that I will explain here:
Formalin Guaiacol FG-Neo has a "Guaiacol" instead of Cresol in FC-Neo as a result, having less irritancy and longer stability.
PERIODON lasts longer to cure with constant Formaldehyde gas appearing.
METHOCOL has a strong effectiveness of calming pains also disinfections.
CREODON has a minimum irritancy against tissues and strong effectiveness of calming pains.
Let's see each caracteristics,In which cases do we use the different types of medications? I will discuss these a bit further with this next demonstration.
Or one could use FG Neo with guaiacol instead of cresol or Periodon which belong to the Fomaldhyde group of medicines. However although these have stronger disinfection power, they have also been shown to be more irritant to tissues.
There are  Methocol and Creodon which belong to the “phenol” group of medicines that are very effective against calming pain, but have less disinfectant powers.
Infected cases and medicines PLEASE CLOSE VIDEO ONE AND OPEN RCT-2. THANKS.
