Glass ionomer cements act as sealants when pits and fissures in the tooth occur and release fluoride to prevent further enamel demineralisation and promote remineralisation. Fluoride can also hinder bacterial growth, by inhibiting their metabolism of ingested sugars in the diet. It does this by inhibiting various metabolic enzymes within the ...
It does not possess anticariogenic effects, is not adherent to tooth structure, and acquires a moderate degree of intraoral solubility. However, zinc phosphate cement can irritate nerve pulp; hence, pulp protection is required but the use of polycarboxylate cement (zinc polycarboxylate or glass ionomer) is highly recommended since it is a more ...
Light curing of a dental filling material. A dental curing light is a piece of dental equipment that is used for polymerization of light-cure resin-based composites. [1] It can be used on several different dental materials that are curable by light. The light used falls under the visible blue light spectrum. This light is delivered over a range ...
A systematic review concluded that for decayed baby (primary) teeth, putting an off‐the‐shelf metal crown over the tooth (Hall technique) or only partially removing decay (also referred to as "selective removal" [5]) before placing a filling may be better than the conventional treatment of removing all decay before filling. [6]
It does not resorb, and is biocompatible, forming a seal against the tooth material that minimizes leakage. [1] Originally, MTA was dark gray in color, but white versions have been on the market since 2002. Bismuth oxide, which was added as a radioopacifier (to make the filling stand out on X-rays), [citation needed] can discolour the teeth. [3]
The tooth must be kept perfectly dry during placement or the resin will likely fail to adhere to the tooth. Composites are placed while still in a soft, dough-like state, but when exposed to light of a certain blue wavelength (typically 470 nm [ 7 ] ), they polymerize and harden into the solid filling (for more information, see Light activated ...
Keeping the soil dry makes harvesting easier, and it helps the bulbs dry and cure faster. Use a garden fork or shovel to loosen the soil and gently lift the garlic bulbs from the earth.
Back teeth showing fissure system. Dental caries is an upset of the balance between loss and gain of minerals from a tooth surface. [3] The loss of minerals from the teeth occurs from the bacteria within the mouth, fermenting foods and producing acids, whereas the tooth gains minerals from our saliva and fluoride that is present within the mouth.
