The history of direct pulp capping - PubMed

In 1920 Hermann, introduced calcium hydroxide for root canal fillings. Between 1928 and 1930 he studied the reaction of vital pulp tissue to calcium hydroxide to prove that it was a biocompatible material. Since then, calcium hydroxide has been recommended by several authors for direct pulp capping, but it took until the middle of 20th century until it was regarded as the standard

Calcium hydroxide | Podcast | Chemistry World

Calcium hydroxide may look an innocent white powder, but it needs to be shown respect. A rather elegant sounding application of calcium hydroxide is as a flocculant, where it is responsible for encouraging a suspended colloid to form flocs. (A floc, incidentally, unlike a collection of sheep, has no k on the end of the word.) This role perhaps loses a little elegance,

Calcium Element | History, Uses, Facts, Physical Chemical ...

The history of calcium dates to 7000 BC, when calcium in the form of lime was used as plasters for making statues and as building material. The name calcium is derived from the word “calx” that is Latin for lime. Another form of calcium, calcium sulphate that is termed as gypsum have been found to be used in the construction of Great Egyptian Pyramid of Giza. Later in 1787,

Calcium hydroxide is a white odourless powder with the formula Ca(OH)2, and a molecular weight of 74.08. It has low solubility in water (about 1.2 g Lÿ1 at 258C), which decreases as the temperature rises; it has a high pH (about 12.5–12.8) and is insoluble in alcohol. This low solubility is, in turn, a good clinical characteristic because a long period is necessary before it

How dangerous is calcium hydroxide?

A notable fact is that calcium hydroxide (Ca(OH)2), one common alkali, can be made quite easily in kitchens by burning eggshells, whose calcium carbonate is then converted into calcium oxide (quicklime, CaO), which can be 'slaked' with water to become calcium hydroxide. Acidity comes in many delicious forms.
