This can occur with or without a mineral imbalance. A common misconception is that calcification is caused by excess amount of calcium in diet. Dietary ...
Calcinosis is the formation of calcium deposits in any soft tissue. [1] It is a rare condition that has many different causes. These range from infection and injury to systemic diseases like kidney failure .
Remineralisation of tooth enamel involves the reintroduction of mineral ions into demineralised enamel. [21] Hydroxyapatite is the main mineral component of enamel in teeth. [22] During demineralisation, calcium and phosphorus ions are drawn out from the hydroxyapatite.
These deposits are commonly found on teeth or dental appliances such as orthodontic brackets. The most common way dental plaque is assessed is through dental assessment in the dental clinic where dental instruments are able to scrape up some plaque.

orthodontic tooth movements; transplantation of teeth; trauma; It is shown that pulp stone occurring in adolescents is significantly associated with carious and/or restored teeth, which suggests a causative relationship of chronic pulp irritation to pulp stone formation.
Calcium deposits known as limbus sign may be visible in the eyes. [7] Symptoms are more common at high calcium blood values (12.0 mg/dL or 3 mmol/L). [6] Severe hypercalcaemia (above 15–16 mg/dL or 3.75–4 mmol/L) is considered a medical emergency: at these levels, coma and cardiac arrest can result.
