How patients and workers exposed to mercury from dental amalgams?

The point at which patients are most exposed is during installation or removal of fillings

The general public is exposed to mercury, for example, eating contaminated fish, using cosmetics, drugs or medical devices containing mercury (such as dental amalgams) or in certain workplaces where mercury is used.
The time at which patients are more exposed to mercury from dental amalgam is during installation or xtracción fillings.

To reduce exposure to mercury from dental patients are best left amalgam fillings in place unless there is a medical reason to remove them.

However, it may be advisable to remove the fillings if you suspect the patient may develop an allergic reaction to any of the metals in the amalgam.
Once the amalgam fillings are placed, patients are exposed to mercury that is released through normal wear, but much less than exposure during placement and removal.

The dental staff is significantly more exposed to the mercury that the general population.

Its main sources of exposure are the vapors released when placing or removing fillings, and the air that emanates from the exhaust systems.

But today dental workers are much less exposed to mercury in the past because the technical and hygiene measures have greatly improved because as the use of amalgam is declining.
