DENTAL CARIES

DENTAL CARIES

Dental caries is an infectious microbiologic disease of the teeth that characterized localized dissolution of inorganic tooth content followed by destruction of the organic content and progress to form a cavity.

Classification

I- According to GV black:
Classified into 6 classes same as GV Black cavity classification.

II- According to surfaces involved:

Pit and fissures caries.
Smooth surfaces caries.
Root caries.

III- According to onset of occurrence (prior condition of tooth):

Primary caries, occur in previously intact tooth.
Secondary (Recurrent) caries occur under previous restoration.

IV- According to caries progression:

Incipient (Initial) caries, not cross the DEJ with almost intact outer enamel surface and can be treated with remineralization, usually no restorative procedures required .
Advanced caries, crossing the DEJ and restoration required.


V- According to severity of the lesion:
Acute or sever, fast progressing destructing the tooth extensively and often lead to pulp involvement. A term Rampant caries is usually used to describe acute caries affecting multiple teeth and its usually occur in children and adolescents.
Chronic caries, slowly progressing affecting particular tooth and pulp involvement is not as common as in active caries.

VI- According to activity of lesion:

Active caries, mean that caries is in state of progression.
Arrested caries, mean that caries stop progressing and this usually occur if caries become in a self cleansing areas (e.g. class II caries may be arrested after extraction of adjacent tooth).
