Common uses include temporary restoration of teeth, cavity linings to provide pulpal protection, sedation or insulation and cementing fixed prosthodontic appliances. [1] Recent uses of dental cement also include two-photon calcium imaging of neuronal activity in brains of animal models in basic experimental neuroscience. [2]
Calcium hydroxide. Calcium hydroxide is a relatively low compressive strength and a viscous consistency, making it difficult to apply to cavities in thick sections. A common technique to overcome this issue is to apply a thin sub-lining of calcium hydroxide, then build up with zinc phosphate prior to amalgam condensation.
Before this treatment modality is introduced, apexification procedures using either immediate placement of mineral trioxide aggregate [3] apical plug or long term-calcium hydroxide treatment [4] were traditionally used to treat immature permanent tooth. Although these treatments often resolve the signs and symptoms of pathosis, they provide ...
Calcium hydroxide is modestly soluble in water, as seen for many dihydroxides. Its solubility increases from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. [8] Its solubility product K sp of 5.02 × 10 −6 at 25 °C, [1] its dissociation in water is large enough that its solutions are basic according to the following dissolution reaction:
Dental lutes can be classified in many ways, some of which are based on: (i) user's knowledge and experience of use [5] conventional: zinc phosphate, zinc polycarboxylate, and glass-ionomer (GI) contemporary: resin-modified glass-ionomer cement (RMGIC) and resin (ii) type of setting mechanism [6]
Calcium hydroxide Ca(OH) 2 is conventionally used as a pulpotomy agent of the permanent teeth but with less long-term success. [1] Calcium hydroxide is a highly alkaline (pH 12) material that has bactericidal effect and has the potential to enhance reparative dentin (dentin bridge) formation. However, it also leads to superficial necrosis of ...
Carbonated calcium-deficient hydroxyapatite is the main mineral of which dental enamel and dentin are composed. Hydroxyapatite crystals are also found in pathological calcifications such as those found in breast tumors , [ 8 ] as well as calcifications within the pineal gland (and other structures of the brain) known as corpora arenacea or ...
A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, [1] including for orthodontic bracket attachment. [2] Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass [3]) and polyacrylic acid, an ionomer.
