Natriumtäyttöä

Natriumtäyttöä, a Finnish term, translates to "sodium filling" and refers to a historical dental procedure. In the past, it was a common method for filling cavities in teeth. This technique involved using a material that contained sodium, which was malleable and could be shaped to fit the tooth's prepared cavity.

The exact composition of these fillings varied, but they often included elements like silver amalgam, which historically contained mercury, tin, copper, and sometimes zinc. Sodium itself was not typically the primary filling material, but rather an additive or component in certain formulations used by dentists. The procedure was chosen for its durability and cost-effectiveness compared to other available options at the time.

Over time, concerns about the materials used, particularly mercury in amalgam fillings, led to a decline in their use. Modern dentistry has introduced a variety of alternative filling materials, such as composite resins, ceramics, and glass ionomers, which are considered safer and more aesthetically pleasing. While natriumtäyttöä is largely a practice of the past, understanding it provides insight into the evolution of dental care and the materials that were once standard.
