Calcium Pyrophosphate can occur naturally in the human body in addition to being manufactured for use in consumer products. It is a calcium salt with a chemical formula Ca2P2O7. Calcium pyrophosphate is found in different forms including crystals, powders, and liquids. It can have a mildly abrasive quality which is why it is often used in toothpaste. When Calcium Pyrophosphate crystals form in and around joints in the body, it can lead to a type of pseudogout arthritis.
Calcium Pyrophosphate Crystal Deposition Disease or CPPD is what forms when Calcium Pyrophosphate crystals begin to form in the cartilage, then moves into body fluids and settle in the joints, which can stimulate inflammation. The medical diagnosis is actually confirmed when joint fluids show the presence of Calcium pyrophosphate crystals. Treatments may include injecting corticosteroids into the joints or the use of non-steroidal anti-inflammatory drugs.
