the material used is carbon wick material But now a days cotton material can be used
What element is used to prevent tooth decay?
fluoride
Which non metal i9s used for filling electric bulb?
graphite
What is a liquid filling machine used for?
Liquid filling machines typically use pressure-overflow fillers, which have a very fast fill rate and can handle a wide range of viscosities. Any leftover product in the filling tubes gets pushed back into the tank, preventing overflow and spillage
What is an amalgam restoration?
An amalgam restoration is when a tooth is repaired using amalgam. Usually, the amalgam is used to fill a hole that is found in a tooth.
What are some good filling materials?
To treat a cavity or cracked tooth a filling is used to fill the area of the tooth where the decayed material was removed or where the tooth is cracked. There are several filling materials available including gold, porcelain, silver amalgam, plastic, and resin.
What is cavity wall?
Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with a porous material. By doing this the porous material absorbs the escaping water and air.
What are cavity walls?
Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with a porous material. By doing this the porous material absorbs all of the air and water and stops it from escaping the house or building.
What is percolation in dental restorations?
when any restorative material (dental cement or amalgam) is filled in the tooth cavity, it adapt to tooth structure chemically or mechanically. But irrespective of material used, there is more or less micro gap between tooth structure and the filling material. Which can allow the oral fluids to enter into it and can cause marginal leakage or marginal staining. This entry of the fluid into the micro leakage of the restoration is known as percolation.

If a dental filling falls out is it okay to put it back?
No. The filling came out because there is something wrong. Either there is decay under or around the filling, which caused it to no longer fit the cavity prep, the bite exerted too much force on the filling breaking it loose, or the filling material used has just worn out. In any case, a new filling needs to be placed, and the cause of the failure needs to be determined and corrected. See your dentist before the tooth requires root canal therapy. That can get very expensive.
What is the difference between a filling and a root canal?
when you get a filling, they drill some of the tooth which has a cavity and fill it. When you get a root canal, they drill all the way down and take out the nerve of the tooth. Getting a root canal is more painful then a filling.
why should the arnalgam used in dental fillings have the same average cofficient of expansion as a tooth what would occur if they were mismatched?
he reason why dental amalgam (a mixture of metals used in dental fillings) should have the same coefficient of expansion as a tooth is because the coefficient of expansion is a measure of how much a material will expand or contract when exposed to changes in temperature. If the coefficient of expansion of the dental amalgam is different from that of the tooth, it can cause problems. If the coefficient of expansion of the dental amalgam is greater than that of the tooth, the filling will expand more than the tooth when exposed to heat, and this can cause the tooth to crack or fracture. Similarly, when the filling contracts more than the tooth when exposed to cold, it can cause the tooth to become loose or fall out. On the other hand, if the coefficient of expansion of the dental amalgam is less than that of the tooth, the filling will not expand as much as the tooth when exposed to heat, and this can cause the filling to become loose or fall out. Similarly, when the filling contracts less than the tooth when exposed to cold, it can cause the tooth to crack or fracture. Therefore, it is important for the coefficient of expansion of the dental amalgam to be as similar as possible to that of the tooth in order to prevent these problems from occurring. In order to achieve this, dentists use a special type of dental amalgam that is specially formulated to have a coefficient of expansion that is similar to that of the tooth.𝘩𝘵𝘵𝘱𝘴://𝘸𝘸𝘸.𝘥𝘪𝘨𝘪𝘴𝘵𝘰𝘳𝘦24.𝘤𝘰𝘮/𝘳𝘦𝘥𝘪𝘳/372576/𝘮𝘶𝘣𝘪𝘳𝘪𝘨𝘪/
What type of material is used to make a white tooth filling?
Most of the material is either made up of porcelain or gold. It is combined with other materials such as composite resin or glass ionomer cement to help hold it in place.
What is the function of the cavity?
A pulp cavity is the central cavity of a tooth containing the pulp (including the root canal) tooth - hard bone like structures in the jaws of vertebrates; used for biting and chewing or for attack and defense. bodily cavity, cavum, cavity - (anatomy) a natural hollow or sinus within the body. root canal - the passage in the root of a tooth through which its nerve and blood vessels enter the pulp cavity
How are caries treated?
Caries (tooth decay) may be treated several ways, depending on where the decay is located, how extensive the decay is, and whether the tooth is considered 'important' to the patient's quality of life. 1. Small cavity, permanent tooth: Decay is removed, the cavity is shaped, and a plastic or silver material is used to 'fill' the cavity. 2. Large cavity, permanent tooth: The decay is removed, the remaining tooth is 'built up' with a plastic material, this is prepped , and a permanent crown is seated on the tooth. 3. Deep decay, permanent tooth: Same as #2, only a root canal procedure is also performed because the decay has reached the nerve of the tooth. 4. Baby teeth: Similar to 1-3 above, but it depends on how long the tooth is expected to remain in the mouth, importance to chewing, cosmetics, etc.
What is a dental filling?
A dental filling, as the name suggests, fills a cavity that is caused by Dental Decay. Fillings can be made of different materials. They can be tooth colored, made of 'composite resin' materials. Silver Amalgam is also used to fill teeth. Should you have any doubt, please consult your dentist for treatment options. Fillings help to fill in spaces in teeth, prevent further damage to the tooth and protect the interior core of the tooth against exterior exposure to substances that may further damage the tooth structure.
At what age is it that you get a filling in your tooth done first with an injection for numbing?
There is no age to get a filling. Teeth only need to be filled if they have a cavity. Not everyone will get a cavity. But pretty much anytime a tooth is filled, it will need to be numbed with an injection. A child should have their first check up by age 4, in my opinion. The suggested age is; I'v heard one and three. How many one year olds will sit in a dental chair for xrays and a cleaning...? So just get children in as soon as possible for check ups. Even if it's just to get them used to going.
