Study Notes
Mercury in Dental Practice
- Amalgam fillings in teeth contain mercury
- Mercury is used in dental fillings due to its ability to bind with other metals, creating a strong and durable filling
Mercury Absorption and Concentration
- After absorption, the mercuric cation (Hg²⁺) concentrates mostly in the kidneys
- The kidneys filter the mercuric cation from the blood, causing it to accumulate in this organ
Symptoms of Acute Mercury Poisoning
- A common symptom of acute mercury poisoning is kidney damage
- Other symptoms may include tremors, skin rashes, and emotional disturbances
Excretion of Mercury
- Mercury is primarily excreted through the kidneys and eliminated in the urine
- Additionally, some mercury is excreted in feces and sweat
Treatment for Acute Mercury Poisoning
- Chelation therapy is used to treat acute mercury poisoning
- Chelating agents, such as dimercaprol, are administered to bind with mercury and facilitate its excretion from the body
