Heavy calcium oxide - The chemical formula of heavy calcium oxide is the same as the one for calcium oxide. It is its properties which differ: by heating calcium nitrate we obtain a very dense calcium oxide, with a modified molecular structure which is compatible with endodotic treatment, strong hydrophilic properties and is no longer exothermic reactive. It should be noted that heavy calcium oxide, when in contact with water (or another liquid), it will be transformed into calcium hydroxide and this new compound is equivalent to the sum of both heavy calcium oxide and liquid. For instance, if you added one part of heavy calcium oxide to four parts of water, you have five parts of calcium hydroxide.not six, nine or more! It is important to understand that heavy calcium oxide when in contact with liquids will not swell to the point to risk fracture to the treated tooth. It will simply be attracted to the liquid in the tubulis, convert to calcium hydroxide and fill them and seal them, protecting them from bacterial infection (ADBQ)
Hydrophilic - Strong attraction to water(ADBQ)
Hypersensitivity – Sharp or sudden painful reaction in teeth when exposed to hot, cold, chemical, mechanical or sweet or salty stimuli. (RCP)
