Classification of caries by intensity, depth of lesion, according to Black and WHO

Caries is the most famous pathology of most countries in the world. This disease is characterized by damage to the dental tissues. A little later, pathological foci are formed, the dentin is softened and a rotting cavity is formed. Today there is not one classification of caries, but only some of them are widely used in dentistry.

What are the methods of

? The most famous classifications of caries are:

1. According to the depth of the lesion.
2. According to Black.
3. According to WHO.
4. Down the river.
5. Clinical.
6. .
7. According to Vinogradova( actual for children).

Classification of the carious process according to the depth of the lesion

This classification of caries is considered the most convenient. It is for this reason that it was widely spread in the domestic space. Dentists note the forms of the carious process, which can be attributed to an uncomplicated and complicated process:

• stain stage( the initial degree of pathology, characterized by the appearance of a dangerous for the enamel focus);

• surface stage( carious process does not apply to dentin);
• middle stage( decay reaches not only enamel, but also dentin);
• deep stage( thin dentinal layer covers the pulp);
• formation of pulpitis( topical for complicated caries);
• formation of periodontitis( relevant for complicated caries).

According to Black

The unique method was proposed and developed in the late nineteenth century. Classification of caries according to Black, "born" in 1896, suggests a strict separation of all carious cavities into five categories.

The main goal of developing this classification of physicians is the standardization of methods for sealing and preparing areas of decay.

For each of the five categories, there is a "proprietary" sealing technique.

A little later in the classification of caries according to Black added a new, sixth category. The modern, final version looks like this:

• the first category( putrefaction is formed on natural fissure sites);
• the second category( molar and premolar contact zones are affected);
• the third category( rotting affects contact surfaces of incisors and canines, the integrity of the cutting edge is not disturbed);
• the fourth category of rotting affects the contact surfaces of incisors and canines, the integrity of the cutting edge is disturbed);
• is the fifth category( rotting extends to the vestibular surfaces of each of the groups);
• is the sixth category in which putrefaction is localized on incisors and canines( cutting edges) and molars( knolls).

According to WHO

Another popular category is the classification of caries according to WHO.It includes the following categories:

• enamel pathology;
• pathology of dentin;
• pathology of cement;
• suspended rotting;
• odontoklaziyu( in the classification of caries according to WHO, it is specified that for this category, the resorption of the roots of affected milk teeth is characteristic).

In the course of the carious process

In this case, the caries classification is a combination of the main four categories:

• acute form( specific changes appear not only on the tooth being "at risk", but also on its neighbors);
• chronic course of pathology( the destruction progresses, the color of the tooth tissue and cavity changes);
• blossoming form( also called acute), in which a large number of teeth and in other places of the oral cavity appear infectious foci;
• is a secondary form( also referred to as recurrent), in which rotting is formed under the fillings and in the area of ​​their location.

Clinical

This method also carries the method name according to Pakhomov.

The physician distinguished five basic forms of the carious process, which is in the spot stage: white, gray, red, brown, black.

Also included are the following categories:

• surface degree( there are several lesions of tooth enamel);
• medium degree( the carious cavity is formed both on the tooth enamel and on the dentin);
• deep degree( the carious cavity is very deep, almost at the bottom of the nerve).

MSDI

In turn, this classification is divided into several subcategories:

1. According to clinical forms.
2. By localization.
3. With the flow.
4. According to the intensity of rot.

Clinical forms of

It is necessary to distinguish the stages of the spot:

• progressing( appearance of white and yellow spots);
• intermittent( appearance of foci of brown hue);
• temporarily stopped( the appearance of foci of dark brown hue);

The stage of the carious defect is also distinguished:

• surface degree;
• degree of ср-не depth;
• Deep degree;
• pathological process of cement( rotting extends to tissues covering the root).

Localization of

The following types are distinguished:

• fissure carious process;
• carious process formed between the teeth;
• cervical caries process.

The process is divided quickly and slowly, as well as stabilized species. By the intensity of decay, I single out a single, multiple and systemic form.

Based on the Vinogradov

It is based on the calculation of the decay intensity index. There are following forms:

• compensated;
• is subcompensated;
• decompensated.

Conclusion

Almost each of these methods repeats each other. Only a qualified dentist can determine how deeply rotting has penetrated, and what caused the development of pathology. After that, a treatment is prescribed, which includes hygiene requirements.
