Statement on Dental Amalgam For dental patients: Dental amalgam is considered a safe, affordable and durable material that has been used to restore the teeth of more than million Americans.
Safe Amalgam Filling Removal: Guidelines for Dentist and Staff 1. Keep the fillings cool during removal. Drilling out an amalgam filling generates a tremendous amount of heat, which causes a dramatic increase in the release of mercury, both as a vapor and in amalgam particles, during the entire removal process.
Dental amalgams the filling with water and air while drilling dramatically reduces the amount of mercury vapor the filling releases. This involves less drilling, because the dentist only drills enough to cut the filling into chunks, which can then be easily removed by a hand instrument or suction.
Use a high-volume evacuator. Most mercury free dentists use a more powerful suction system than those used by most pro-amalgam dentists. This helps capture more of the mercury vapor and particles. Use additional air purification. This can be helpful, but we agree with those mercury free dentists who believe that the patient can be adequately protected without such a system.
Provide the patient Dental amalgams an alternative source of air. But during the actual amalgam filling removal, the patient should be provided with a protective mask through which to breathe either compressed air from a tank, air from a source outside the office, or oxygen from a tank.
Always instruct the patient to breathe through the nose and avoid breathing through the mouth while the fillings are being removed. We think this is especially important for pregnant and nursing mothers, patients who have existing health issues related to mercury, allergies, or immune system problems.
Use a rubber dam. A rubber dam isolates the tooth or teeth being worked on. Even though mercury vapor can pass through the rubber dam, we believe that a rubber dam makes it easier to evacuate the filling material and prevent amalgam particles from being swallowed.
As long as the patient breathes through the nose, little if any mercury vapor will pass through the rubber dam. Finally, it offers an isolated and dry field for placing the composite filling.
But anyone who is concerned about minimizing mercury exposure should insist on its use. In any case, the patient should be instructed not to swallow while the fillings are being drilled.
As in everything, there are exceptions. With some teeth, particularly 3rd molars, or so-called wisdom teeth, it may not be possible to place a rubber dam. As long as the dental team uses all the other protocols, this is acceptable. Immediately dispose of filling particles.
While a dentist working alone can safely remove mercury amalgam fillings, it is easier for everyone to have an assistant working with him throughout the removal procedure.
This will ensure constant suction and a continuous flow of air and water. The patient should make every effort not to swallow during this procedure. We also suggest that after the rinsing procedure, the patient use a small amount of water and gargle as far back into her throat as possible.
The patient should not swallow this watery residue! Instead, he should spit it into a sink or cup.
Keep room air as pure as possible. There are a number of effective ways to purify the air in the office.Mercury is one of the world’s most poisonous substances, and yet dentists routinely use it in amalgams to fill our teeth.
Forty years ago, Dr.
Hal Huggins questioned this practice, and now legions of dentists, researchers, and citizens are adding their voices of concern. Important amalgams Zinc amalgam. Zinc amalgam finds use in organic synthesis (e.g., for the Clemmensen reduction).
It is the reducing agent in the Jones reductor, used in analytical regardbouddhiste.comly the zinc plates of dry batteries were amalgamated with a little mercury to prevent deterioration in storage. It is a binary solution (liquid-solid) of mercury and zinc.
This discussion of the dental amalgam controversy outlines the debate over whether dental amalgam (the mercury alloy in dental fillings) should be regardbouddhiste.comters claim that it is safe, effective and long-lasting while critics argue that claims have been made since the s that amalgam is unsafe because it may cause mercury poisoning and other toxicity.
Dental amalgam is a mixture of mercury, silver, tin and copper. Mercury, which makes up about 50% of the compound, binds the metals together to provide a strong, durable filling. When combined with the other metals, the mercury in fillings forms a safe, stable compound. Crowns & Bridgework.
Dentistry is an art as well as a science; dental crowns offer a perfect example of this. A dental crown or “cap” is a covering that fits over a damaged, decayed or unattractive tooth. Dental/Cancer Connection by Dr.
