Now, without the restoration, we will start removing the cavities.

And to carry out this cavity removal we will do it based on a concept called the Peripheral Sealed Zone.

Why are we going to use this technique to remove cavities?

Because that way we can reduce the risk of pulp exposure.

We don't need to remove all that decayed tissue that is there.

In this technique, when you use the caries detector, you will have the tooth pigmentation.

You will wash, you will dry, I will show everything in the video in practice to you can see exactly what it is like.

Let me explain to you then you watch the video.

You pigmented, and everything that pigmented, whatever is in the most outside of your preparation, not in the deepest part, in the external part, you will completely remove everything that is pigmented.

You will create a Peripheral Sealed Zone, that's why it has that name, which will be about 1 to 3 millimeters.

And inside, you you will evaluate what pigmented.

Depending on the type of detector you will use, it may be based on the red or pink.

And this color can be more intense or weaker.

The more intense it is, this is a cavity that is actually infected and altered. You need to remove it.

And the clearer, she went to infected, but it is not altered. You can reminalize this cavity.

So whenever there's a light pink in this inner region of the seal zone, you leave it.

And when you have a pink or a red intense, you will evaluate.

If it is superficial, there is no risk of pulp exposure, you remove. Now, if its deep, there's no problem to leave.

Why?

Because as you have the peripheral seal, there's no continuity of nutrition of the bacteria there.

So, you won't have the proliferation of this cavity. It won't go any further.

You will be able to control this cavity inside the peripheral sealed.

Everything I'm telling you here on this subject, of caries removal, we talk much more in-depth for anyone who wants, within a course we have on ADHESION.

We talk all about bonding, including things that affect the bonding such as caries removal.

In this course we are on, the objective is to be more objective in the preparation and how the We are going to do our ONLAY.

So, we are going over the cavity removal, but whoever wants to go deeper has this another ADHESION course.

So let's see now in the video exactly like I removed that caries and how will you do also in your patient.

We're going to start now, the removal of decayed tissue.

We will use the technique of the Peripheral Sealed Zone.

To do this, we will need a caries detector and a steel spherical bur for low rotation from Maillefer.

So that we can carry out a controlled removal

of this decayed tissue. We will paint with caries detector throughout the tooth.

It needs to be very dry for you be able to provide correct evidence this carious tissue, and will remove the decayed tissue with the spherical bur at low speed, a very low speed.

You will start by removing all the external decay that you have, especially in this external zone of carious tissue, for you to create precisely peripheral sealed zone.

In this region that has more or less 1 to 3 millimeters, you have to remove completely all this decayed tissue.

And in the inner region of this peripheral seald zone, you will evaluate the type of pigmentation.

So you can see if it is a external type of cavity, you completely remove it or if it's an internal cavity, doesn't need for you to remove, mainly in deep regions, which if you remove it has a risk of exposure.

We even talk in more detail about that , exactly how to do this caries removal in our ADHESION course.

But here what you have to know is that you will do all the cavity removal and for this you have to paint the tooth several times.

It is not enough to paint once with the caries detector and think everything is resolved.

No, paint two, three, four times if necessary for you to see if you really created this peripheral sealed zone.
