Let's try what we feel! Place a piece of aluminum foil on top of a crowned tooth. Take a bite. What did you feel? It was a feeling of pain, like a little shock? To chew some gum or sucking a bullet that "stuck" a piece of foil or when two fillings come in contact, you can have the same feeling or not. Do you know what material the dentist used to close your tooth? Opening his mouth you can get your questions answered. There are two types of materials known: the amalgam, mercury metal alloy with other metals, and polymer resins (porcelain). You can identify if your teeth are filled with amalgam or resin. Know that amalgams have different color natural color of your tooth. While, in the filling resin, is similar to the color of his teeth. The long molecules of the polymeric resin are formed by carbon atoms, oxygen and hydrogen. But which of the two materials causes a feeling of pain, a "shock"? Recalling that the electric shock is caused by an electric current (moving electrons) passing through our body. The sensations and the consequences of electric shock depends on the intensity of the electric current, the relationship between the amount of charge that passes per unit time in a portion of the conductor. The feeling of "pain", ie the "shock" that some felt, indicating the passage of electrical current between the foil and your crowned tooth. The amount of electric charges (electrons) involved was very small, because the shock that led some did not have any life-threatening. How Did This electrical current? Whence came the electrons required for some of you feel the "shock"? Numerous metals are used in their day-to-day, for example copper and zinc. The metal copper is found in electric cables and metal zinc is found in the gutters drain rainwater from roofs.

Idemo pokušati ono što osjećamo! Stavite komad aluminijske folije na vrhu okrunjenim zuba. Uzmi zalogaj. Što ste se osjećali? To je osjećaj boli, kao mali šok? Žvakati žvakaću ili sisa metak da je "zapela" komad folije ili kada se dvije plombe dođe u dodir, možete imati isti osjećaj ili ne. Znate li što je materijal stomatolog da se zatvori svoj zub? Otvaranje usta možete dobiti odgovore na pitanja. Postoje dvije vrste materijala poznate: amalgam, živa metalne legure s drugim metalima, i polimer smole (porculan). Možete prepoznati ako su vam zubi su ispunjeni amalgamom ili smole. Znaj da amalgama imaju različite boje prirodnu boju zuba. Iako, u punjenje smole, sličan je boje njegovih zuba. Duge molekule polimernog smole nastaju atoma ugljika, kisika i vodika. No, koji je od dva materijala uzrokuje osjećaj boli, "udara"? Podsjećajući da je strujni udar uzrokuju električne struje (pomični elektroni) prolaze kroz naše tijelo. Osjeti i posljedica strujnog udara ovisi o intenzitetu električne struje, odnos između količine naboja koji prolazi po jedinici vremena u dijelu vodiča. Osjećaj "boli", odnosno "šok" koji su neki osjetili, što ukazuje na prolaz električne struje između folije i vaše okrunjen zub. Količina električne optužbi (elektroni) koje su sudjelovale bila vrlo mala, jer je šok koji je vodio neki nisu imali bilo opasne po život. Kako je ovaj električnu struju? Odakle je došao elektrona koji su potrebni za neke od vas osjećaju "šok"? Brojni metali koriste se u dan-to-day, npr. bakar i cink. Metal bakar se naći u električnim kabelima i metal Cink se nalazi u oluke odvod oborinskih voda s krovova.
