What do you know about calcification?

Pathologic calcification

Calcification is the deposition of calcium salts in body tissues.

It normally occurs in the formation of bones and teeth but calcium can be deposited abnormally in soft tissue, causing it to harden.

The calcium is usually deposited as-  

Ø  calcium phosphate,

Ø  calcium carbonate and

Ø  hydroxyapatite in normal bones and teeth.

Pathologic calcification is the deposition of calcium salts in tissues other than bones and teeth.

There are three types of pathologic calcification. These are-

1.      Dystrophic calcification,

2.      Metastatic calcification and

3.      Calcinosis circumscripta.
