1. Dentistry
a. any of various substances (metal, plastic, etc.) for inserting into the prepared cavity of a tooth
b. the cavity of a tooth so filled
2. Textiles another term for weft



in dentistry, the restoration of the shape and physiological functioning of a tooth by means of an inlay. The filling of teeth prevents progress of dental caries and isolates affected tissues from the microorganisms present in the mouth.

Cavities formed in the hard tissues of the teeth are filled with a malleable material that eventually hardens. A tooth is prepared to receive a filling by the surgical excision of tooth tissues that have lost their firmness. A cavity of a definite outline is then formed. Temporary fillings are sometimes used to cover cavities in which medicinal substances have been applied.

Permanent fillings are made from materials with sufficiently high sturdiness, hardness, and resistance to the effects of saliva. They differ little in color from the crown of the tooth and are harmless to both the tooth and the entire body. Filling materials include phosphate cements, silicate cements, silicophosphate cements, acrylic plastics, preparations based on epoxy resins, and amalgams consisting of a hard solution of metals (silver) in mercury. When filling teeth with amalgams, plastics, or silicate cements, a packing of phosphate cement or artificial dentin (zinc-sulfate cement) is made, and then the filling material is injected into the tooth canal with a special probe needle or plugger.

They added that there are no comparable data on the risks associated with resin composite fillings, which are the most commonly used alternative to amalgam fillings.

The repository also contained information about patient lifestyles, including smoking and drinking habits, and a DNA sample from each patient -- allowing the team to investigate whether patient lifestyle and genetic factors could affect the failure rate of composite fillings.
In a five-year randomized trial, researchers at Children's Hospital in Boston tested kidney function, IQ, memory, and visual skills in 534 children with amalgam or tooth-colored composite fillings. No harm was found from the mercury exposure.
Children with amalgam fillings had a nonsignificant increase in IQ scores compared with those receiving resin composite fillings
In addition, employers are being crunched for money and are moving to lower-cost plans, such as 100-50-50 plans, in which 100% of preventive services, including oral exams, cleaning and X-rays, is covered once the deductible is met; 50% of basic services, such as routine extractions, composite fillings and emergency exams; and 50% of major treatment services, said Ganoni.
Any woman planning to have children should consider having her amalgam fillings replaced with tooth-colored composite fillings. More information can be obtained at
Both groups of researchers noted that resin composite fillings are more expensive than amalgam; are more difficult to work with; and appear to be less durable, as they have higher failure rates.
Two recent studies--one from Portugal and the other from the United States--showed no drop in IQ or impairment of memory, coordination, concentration, or kidney function in children with silver fillings compared to matched children with resin composite fillings.
So the NHS discourage the composite fillings. Dentists normally only offer them if the patient goes private - at a cost of up to pounds 80.
