In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth . This process of precipitation kills the bacterial cells within dental plaque, but the rough and hardened surface that is formed provides an ideal surface for ...
Potassium bitartrate, also known as potassium hydrogen tartrate, with formula K C 4 H 5 O 6, is a chemical compound with a number of uses. It is the potassium acid salt of tartaric acid (a carboxylic acid). Especially in cooking, it is also known as cream of tartar.
Bleeding on probing (BoP) which is also known as bleeding gums or gingival bleeding is a term used by dentists and dental hygienists when referring to bleeding that is induced by gentle manipulation of the tissue at the depth of the gingival sulcus, or interface between the gingiva and a tooth.
A tartrate is a salt or ester of the organic compound tartaric acid, a dicarboxylic acid.The formula of the tartrate dianion is O − OC-CH(OH)-CH(OH)-COO − or C 4 H 4 O 6 2−. [1]The main forms of tartrates used commercially are pure crystalline tartaric acid used as an acidulant in non-alcoholic drinks and foods, cream of tartar used in baking, and Rochelle salt, commonly used in ...

Oleums can be described by the formula ySO 3 ·H 2 O where y is the total molar mass of sulfur trioxide content. The value of y can be varied, to include different oleums. They can also be described by the formula H 2 SO 4 ·xSO 3 where x is now defined as the molar free sulfur trioxide content. Oleum is generally assessed according to the free ...
A frequent method for displaying formulas on their own line has been to indent the line with one or more colons (:). Although this produces the intended visual appearance, it produces invalid html (see Wikipedia:Manual of Style/Accessibility § Indentation). Instead, formulas may be placed on their own line using < math display = block >.
