Caries on the root surface of a tooth, characterized by a rough texture, thin cementum, and less defined margins.

Enamel caries progress from a non-cavitated white spot (demineralization) to a cavitated lesion over an estimated 18 months.

Early enamel caries stage, visible as white spots on dry tooth surfaces. Characterized by demineralization and loss of enamel translucency

Arrested caries lesions which are intact, discolored (brown/black), and resistant to further decay due to remineralization.

Categorization of tooth decay, starting with enamel caries, and progressing accordingly.

Caries in the enamel of the tooth crown.

Pre-cavitation enamel caries has four zones.

Advanced stage of enamel decay where a visible cavity forms

A demineralization and remineralization imbalance leading to tooth damage.

A tooth surface with a cavity, holding biofilm better, increasing decay.

The layer under tooth enamel, less resistant to acid than enamel.

Tooth decay starting in grooves/pits, expanding as it penetrates.

Tooth decay on flat surfaces, near the gums or contact points.

The boundary between tooth enamel and dentin.

Locations most vulnerable to decay; pits, fissures, smooth surfaces, and root surfaces

Faster spreading of tooth decay into dentin after reaching the DEJ.

The area of dentin invaded by bacteria, characterized by widened and distorted tubules filled with bacteria.

Identifying different dentin layers (infected, affected, and healthy) through visual inspection (color, paleness, and brownness), tissue hardness (hard, soft), and disclosing dyes (red, pale, and pink).

The pulp-dentin complex reacts to caries attacks by attempting remineralization and tubule blockage in three ways: Mild slow attacks, moderate attacks, and severe, rapid attacks characterized by high acid levels.

A vital pulp can repair demineralized dentin by remineralization of intertubular dentin and apposition of peritubular dentin. This repair happens only if the tooth pulp is vital.

Dentin with more mineral content than normal, appearing shiny and dark, feeling hard, and sealing off the tubules to wall off a lesion.

Higher activity of caries, leading to bacterial invasion of dentin and releasing irritants like acid, enzymes, bacteria, and debris.

Severe caries activity can damage odontoblasts and their extensions, causing mild pulp inflammation.

Sclerotic dentin significantly reduces dentin permeability due to decreased tubule lumen diameter.
