Dental Amalgam

Amalgam dental restoration, also known as dental amalgam silver filler, is the first choice for repairing teeth. These silver fillers have been used for over 100 years to fill the collapsed cavities already. There are many questions "What is a dental amalgam?" Dental amalgam is a mixture of powder alloy, metal, mercury. However, the safety of such mercury-containing filler materials has several problems. According to the US Food and Drug Administration, amalgam is in the same class as gold and composite filler, there is no safety problem as before.

Dental amalgam is a mixture of liquid (elemental) mercury and metal consisting of silver, tin, copper powder alloy. Approximately 50% of dental amalgam is elemental mercury. The chemical nature of elemental mercury makes it possible for it to react with silver / copper / tin alloy particles and combine them to form amalgam. Once the dental amalgam is in place, the dentist first dents the tooth to remove caries and then shapes the cavity to place the amalgam filling. Then, under appropriate safety conditions, the dentist mixes the powder alloy with liquid mercury to form an amalgam putty. (As shown, these components are supplied to the dentist in capsule form.) The softened amalgam putty is placed and molded in a prepared cavity where it solidifies rapidly into a solid filler .

According to GeirBjørklund, there is a sign that dental amalgam was used by Chinese Tang Dynasty (618-907 AD) and German Strockerus around 1528. Evidence for dental amalgam first appeared in Materia Medica, a medical text newcomer in the Tang Dynasty era. "A new revised version of grass" was created by Su Gong Su Gong in 659, made of tin and silver. History suggests that the use of amalgam may be earlier than the Tang dynasty. In the Ming dynasty, the composition of the early dental amalgam was first announced, and the article published in 1505 by Liu Wentai included "100 mercury, 45 shares of silver, 900 tin of tin". Since the introduction of amalgam in the western world in the 1830's, amalgam has become a controversial controversy due to its mercury content. The early amalgam was made by mixing a mixture of mercury and silver coins. This is the beginning of the so-called first dental amalgam war.
