Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
Metastatic calcification can occur widely throughout the body but principally affects the interstitial tissues of the vasculature, kidneys, lungs, and gastric mucosa. For the latter three, acid secretions or rapid changes in pH levels contribute to the formation of salts. [4]
Structurally, pulp stones can be classified as true and false pulp stones. True pulp stones are made up of dentine that is lined by odontoblast. True pulp stones are quite rare. On the other hand, false pulp stones are made up of concentric layers of mineralised tissue around blood thrombi, collagen fibres, or dying and dead cells.
The tonsils contain a plethora of white blood cells that help your body fight off infection and disease, according to Cleveland Clinic. Tonsil stones are hard white or yellow masses that form on ...
A calculus (pl.: calculi), often called a stone, is a concretion of material, usually mineral salts, that forms in an organ or duct of the body. Formation of calculi is known as lithiasis (/ ˌ l ɪ ˈ θ aɪ ə s ɪ s /). Stones can cause a number of medical conditions.
First, in the "precalcific stage", something causes tendon cells to transform into other cells that can act as sites for calcium deposition. [2] This is followed by the two-part "calcific stage"; first calcium is deposited (the formative phase), then the body begins to break down the calcium deposit (the resorptive phase). [ 2 ]
Inflammatory arthritis—which includes rheumatoid arthritis and psoriatic arthritis—affects your entire body since they’re autoimmune diseases, meaning your immune system goes a bit haywire ...
