Karieslägen

Karieslägen refers to the various stages or degrees of dental caries, commonly known as tooth decay. Understanding these stages is crucial for diagnosis and treatment planning in dentistry. The progression of caries is typically described in a stepwise manner, reflecting the increasing depth of tissue destruction.

The initial stage, often referred to as enamel demineralization or white spot lesion, involves the loss of mineral content from the tooth's enamel surface. At this point, the tooth structure is still intact, and the process may be reversible with appropriate preventive measures. If left untreated, the demineralization continues, leading to the breakdown of the enamel surface and the formation of a visible cavity.

Once the decay reaches the dentin, the layer beneath the enamel, it progresses more rapidly due to dentin's softer structure. This stage is characterized by the formation of a distinct hole or cavity in the tooth. The depth and extent of dentin involvement determine the severity of the lesion. Further progression can lead to the decay reaching the pulp, the innermost part of the tooth containing nerves and blood vessels.

When caries affects the pulp, it can cause significant pain, inflammation (pulpitis), and potentially infection. This advanced stage often requires more complex treatments such as root canal therapy or extraction. The classification of karieslägen helps dentists to assess the current state of the decay and to predict its potential for future progression, guiding them in selecting the most effective restorative or preventive interventions.
