Dry caries is a dental term referring to a type of decay that affects tooth enamel, leading to the formation of cavities. The correct spelling of this term is [ˈdraɪ ˈkɛəriːz], with the first word pronounced as "dry" and the second word pronounced as "caries" with an elongated vowel sound. The term "dry" refers to the absence of moisture or fluids in the tooth, which can contribute to the development of this type of decay. Patients with dry mouth conditions are often at a higher risk for developing dry caries.
Dry caries, also known as arrested caries or inactive caries, refers to a medical condition that occurs in the teeth where the dental decay process has stopped or been halted. It is a type of cavities that have reached a point of stability or inactivity.
Dry caries can develop as a result of various factors, such as changes in oral hygiene practices, alterations in the oral environment, or the application of preventative measures. This dental condition is characterized by the cessation of the progression of the carious lesion, resulting in the hardening of the decayed tissue. The affected area becomes demineralized, causing the softened enamel or dentin to harden due to the reabsorption of minerals, such as calcium and phosphate, from saliva.
Typically, dry caries appear as brown or black discolorations on the surface of the tooth, indicating the presence of inactive decay. Unlike active caries that continue to progress and cause further damage to the tooth structure, dry caries do not exhibit any signs of active bacterial infection or decay advancement. Dentists often consider dry caries to be sealed off or "arrested," as they are not actively causing harm to the tooth.
It is important to note that although dry caries do not pose an immediate threat to oral health, regular dental check-ups and appropriate oral hygiene practices are still necessary to prevent reactivation or progression of decay. If left untreated, dry caries can potentially undergo a process known as remineralization, where the mineralized tooth structure is restored, or may lead to the reactivation of the decay process, making it essential to monitor and maintain the oral health of individuals with this condition.

The term "dry caries" does not have a specific etymology as it is a combination of two words from different origins: "dry" and "caries".
The word "dry" has Old English origins, derived from the Old English word "drȳge", which meant "free from moisture" or "lacking liquid". Over time, the word "dry" has remained relatively unchanged in meaning and spelling.
On the other hand, the word "caries" originates from Latin. It is derived from the Latin verb "carēre", meaning "to decay" or "to be rotten". "Caries" refers specifically to the decay or rotting of bone or teeth.
So, when combined, "dry caries" describes a specific type of tooth decay that lacks moisture or does not involve active infection or pus formation.
