Final answer:
Amalgamation is the process of mixing elements within an amalgam capsule, commonly used in dentistry to create dental amalgams for fillings.
Step-by-step explanation:
The process of mixing two or more things together within an amalgam capsule is called amalgamation. In dentistry, this specifically refers to the creation of a dental amalgam, which is an alloy used for filling cavities. The amalgam is typically made from a combination of metals such as silver, tin, and copper, with mercury being used due to its unique property of binding well with these metals. Dental amalgams contain approximately 50% mercury by weight, and this mercury binds with the powdered metal alloy inside the amalgam capsule to form the solid filling material.
