A transmissible, infectious disease caused by bacteria interacting with sugars on teeth, leading to tooth decay.

A film of bacteria, food, and cells on teeth, it's an etiological factor, not the direct cause of caries.

Microorganisms that ferment carbohydrates and produce acids, demineralizing tooth structure.

An organic film that sticks to teeth, serving as a starting point for bacteria.

Acid produced by bacteria, causing tooth demineralization.

Loss of calcium and phosphate from tooth structure due to acid attack.

The critical pH level (5.5) below which tooth demineralization occurs.

Common bacteria linked to dental caries.

Four zones of enamel affected by caries: Normal, Lesion, Translucent, Dark.

A zone in enamel where light cannot pass, indicating advanced caries.

Four zones in dentin affected by caries: Normal, Sub-transparent, Transparent, Turbid.

Dentin completely decomposed with bacteria present, not salvageable.

Demineralized dentin without bacterial invasion, potentially salvageable.

Early enamel lesions, sometimes darkening with remineralization.

Severe tooth decay in infants due to prolonged exposure to sugars.
