Dental Caries Overview

Dental caries typically begins in the enamel, which is the outermost layer of the tooth.
The process of demineralization and remineralization in enamel is crucial; disruption of this balance increases the risk of caries formation.

Progression of Dental Caries

In late-stage development, decay can advance into deeper layers of the tooth, potentially reaching the dentin and pulp.
When a favorable oral environment is established, caries lesions can undergo remineralization and may even arrest, halting further progression.

Characteristics of Arrested Lesions

Arrested lesions appear dark due to mineral changes but are stable and non-progressive.
Characteristics include reduced size, lack of symptoms, and a tough surface that protects against further decay.

Factors Influencing Caries Lesions

The caries process can be halted through good oral hygiene, fluoride use, dietary modifications, and proper saliva flow, leading to the arrest of lesions.
If an unfavorable oral environment persists—characterized by poor hygiene or high sugar diets—caries lesions will further progress, potentially resulting in tooth extraction or advanced decay.

Implications of Pulp Involvement

If dental caries involve the pulp, it can lead to pulpitis, inflammation of the pulp tissue, requiring more extensive treatment like root canal therapy or extraction.
