Types of Caries

they are not all the same. In fact, there are many types of cariogenic processes, distinguished on the basis of:

Type of injury;
Evolution of caries;
Location and form of the infection;
Depth of damage.

The analysis of the type of caries is essential for the dentist: by studying the characteristics of the dental infection, the number and its precise location, it is in fact possible to make a correct and unequivocal diagnosis, or to obtain a precise clinical evaluation.

Grade 2 caries: the dental infection, which originates in any case from the enamel, has also affected the superficial or deep dentin. Even in this phase, the filling can completely restore the tooth.

Grade 3 caries: Caries has evolved into pulpitis. The infection, which also involved the dental pulp, cannot be treated with a simple filling: in these circumstances, the most suitable intervention is devitalization. If the tooth involved is a third molar, the recommended intervention is instead the extraction of the wisdom tooth.

Grade 4 caries: the most severe type of caries ever. The tooth has necrotic pulp with evident involvement of the periodontal tissues of the root apex. Grade 4 caries is included in the list of periapical diseases.

Caries from ionizing radiation.

or black. Generality The patient complains of a marked dentinal hypersensitivity, a clear symptom that suggests an "imminent inflammation of the pulp (pulpitis). Dentin sensitivity is not particularly pronounced. Pulpitis, if it occurs, tends to appear late. , the walls of the pulp canal are exposed in the oral environment. The central caries begins on these surfaces and spreads from the tubules of the dentine towards the external surface (reverse direction compared to the classic carious process).

As the lesion progresses, the walls of the root are gradually thinned and destroyed: in so doing, there is a migration outward of the same root which sometimes disappears after a few years.

as a consequence of a gingival recession.

However, the carious process occurs around these necks without affecting the enamel: by not having to pierce the enamel, bacteria are facilitated in their unstoppable destructive process. Finding no impediments, the microorganisms are able to easily reach the dental pulp, creating greater damage (pulpits) and in a short time.

of these workers are targeted by infections of all kinds, including tooth decay.

Carious lesions can be multiple, extensive, diffuse, brittle, pigmented, softened, or extremely sensitive. If not carefully treated, these dental infections can escalate, leading to pulpits and tooth loss.

of the pulp. Caries from ionizing radiations can degenerate: among the complications of dental infection there are granulomas and osteomyelitis.

These particular diseases are often considered to be different from other types of tooth decay.
