An infectious microbiologic disease of the teeth that results in the localized dissolution of the calcified tissues

Multifactorial, transmissible, infectious oral disease caused primarily by the complex interaction of cariogenic oral flora, biofilm, with fermentable carbohydrates on the tooth surface over time

consortium of microorganisms that stick to a tooth surface.

The microorganisms are embedded in an

determined by biological, behavioral, psychosocial, and environmental factors. As a consequence of this process, a caries lesion develops.

number of teeth/surfaces that have caries lesions (at a specified threshold), restorations, and/or are missing due to caries, accumulated by an individual, up to a designated point in time.

The most accepted theory that explains dental caries formation, the acid theory, was proposed by W.D. Miller.

The loss of integrity of the tooth, the cavitation, is the earliest sign of dental caries.

The configuration of dental caries on smooth surface assumes double cone appearance with the apices pointing to the pulp.

A caries lesion adjacent to an existing restoration, crown, or sealant is a recurrent caries.

A carious lesion that has mineralized due to exposure to minerals in the saliva is called arrested caries.
