Material Safety Data Sheets (MSDS’s)
for Dental Amalgam
The dental associations tell us it is safe. The universities still
teach dental students to use this material, but really do you need
to be an Einstein to know that it is dangerous.
All you need to do is read what the manufacturers say about their
own products! Below are selections from a variety of Material Safety
Data Sheets on dental amalgam. MSDS’s in Australia must be publicly
available. You can request to see them.
Many have this ‘seal of approval’ by the American Dental
Association

Contraindication
The use of amalgam is contraindicated;
1. In proximal or occlusal contact to dissimilar metal restorations.
2. In patients with severe renal deficiency.
3. In patients with known allergies to amalgam.
4. For retrograde or endodontic filling.
5. As a filling material for cast crown.
6. In children 6 and under.
7. In expectant mothers.
Side Effects/Warning
Prior to use, read the MSDS information and product instructions
for this item.
Exposure to mercury may cause irritation to skin, eyes, respiratory
tract and mucous membrane. In individual cases, hypersensitivity
reactions, allergies, or electrochemically caused local reactions
have been observed. Due to electrochemical processes, the lichen
planus of the mucosa may develop.
Mercury may also be a skin sensitizer, pulmonary sensitizer, nephrotoxin
and neurotoxin.
After placement or removal of amalgam restorations, there
is a temporary increase of the mercury concentration in the blood
and urine.
Mercury expressed during condensation and unset amalgam may cause
amalgamation or galvanic effect if in contact with other metal restorations.
If symptoms persist, the amalgam should be replaced by a different
material.
Removal of clinically acceptable amalgam restorations should be
avoided to minimize mercury exposure, especially in expectant mothers.
Precautions
The number of amalgam restorations for one patient should be kept
to a minimum.
Inhalation of mercury vapor by dental staff may be avoided by proper
handling of the amalgam, the use of masks, along with adequate ventilation.
Avoid contact with skin and wear safety glasses and gloves.
Store amalgam scrap in well sealed containers. Regulations for disposal
must be observed.

MATERIAL SAFETY DATA SHEET
1.1 Product Trade Name: Mercury
1.2 Part (Item) Number: 904061
Health affects and first aid
Inhalation: Acute: Inhalation of a high concentration of
mercury vapor can cause almost immediate dyspnea, cough, fever,
nausea and vomiting, diarrhea, stomatitis, salivation, metallic
taste, gingivitis, and cardiac abnormalities. Respiratory irritation
may occur with chest pain and tightness. Symptoms may re solve or
may progress to necrotizing bronchiolitis, pneumonitis, pulmonary
edema, pneumothorax, interstitial fibrosis, and death. Acidosis
and renal damage may also occur. Allergic reactions that may occur
in previously exposed persons include dermatitis, encephalitis,
and death. Metal fume fever, an influenza-like illness, may occur
due to the inhalation of freshly formed metal oxide particles sized
below 1.5 microns and usually between 0.02-0.05 microns. Symptoms
may be delayed 4-12 hours and begin with a sudden onset of thirst,
and a sweet, metallic or foul taste in the mouth. Other symptoms
may include upper respiratory tract irritation accompanied by coughing
and a dryness of the mucous membranes, lassitude and a generalized
feeling of malaise. Fever, chills, muscular pain, mild to severe
headache, nausea, occasional vomiting, exaggerated mental activity,
profuse sweating, excessive urination, diarrhea and prostration
may also occur. Tolerance to fumes develops rapidly, but is quickly
lost. All symptoms usually subside within 24-36 hours.
Inhalation: Chronic: Inhalation of mercury vapor
over a long period may cause mercurialism which is characterized
by fine tremors and erethism. Tremors may affect the hands first,
but may also become evident in the face, arms, and legs. Erethism
may be manifested by abnormal shyness, blushing, self-consciousness,
depression or despondency resentment of criticism, irritability
or excitability, headache, fatigue, and insomnia. In severe cases,
hallucinations, loss of memory, and mental deterioration may occur.
Concentrations as low and 0.03 mg/m3 have induced psychiatric symptoms
in humans. Renal involvement may be indicated by proteinuria, albuminuria,
enzymuria, and anuria. Other effects may include salivation, gingivitis,
stomatitis, loosening of the teeth, blue lines on the gums, diarrhea,
chronic pneumonitis and mild anemia. Repeated exposure to mercury
and its compounds may result in sensitization. Intrauterine exposure
may result in tremors and involuntary movements in the infants.
Mercury is excreted in breast milk. Paternal reproductive effects
and effects on fertility have been reported in male rats following
repeated inhalation exposures.
Skin contact: Acute : Direct contact
with liquid may cause irritation and redness. Small amounts of mercury
may be absorbed through intact skin. Allergic reactions that may
occur in previously exposed persons include dermatitis, encephalitis,
and death. Subcutaneous introcuction, from handling broken thermometers,
may result in local inflammation, granulomatous skin reactions,
and slight signs of mercury poisoning including digestive disorders,
metallic taste in the mouth, and neuropsychic disorders.
Skin contact: Chronic: prolonged or repeated exposure
may result in dermal sensitization and systemic effects as detailed
in chronic inhalation exposure. Skin contact: Get medical attention
immediately.
Eye contact: Acute: Direct contact with liquid
may cause irritation and redness. Animal studies indicate diffusion
and absorption of mercury into the tissues of the eye may occur.
No clinical signs of conjunctivitis or inflammation occurred.
Eye contact: Chronic: Mercury exposure from inhalation
ingestion, or skin contact may be indicated by mercurialentis, discoloration
of the crystalline lens, on slit lamp examination of the eye.
Ingestion: May cause burning of the mouth and throat,
thirst, nausea and vomiting. Metallic mercury is not usually absorbed
sufficiently from the gastrointestinal tract to induce an acute
toxic response. Rarely, a large single dose may result in sign and
symptoms of chronic inhalation is sufficient amount of mercury are
retained in the body.
Chronic: Repeated ingestion of small amount of mercury may result
in the absorption of sufficient amounts to produce toxic effects
as detailed in chronic inhalation exposure.

HANDLING AND STORAGE
Handling: Do not breathe powder and avoid exposed mercury surfaces.
Wear appropriate gloves, goggles, and protective clothing to prevent
skin contact. Wash thoroughly after handling. Keep away from food,
drink and around animal feed stuffs.
Storage: Keep container tightly closed and dry. Storage in large
quantities (as in warehouse) should be in a ventilated, cool area.
Do not store in metal containers. Keep away from sources of ignition
and elevated temperatures.
TOXICOLOGICAL INFORMATION
Chronic Health Effects: Inhalation of mercury vapours, dusts or
organic vapours, or skin absorption or mercury over long periods
can cause mercurialism. Symptoms include tremors, inflammation of
mouth and gums, excessive salivation, stomatitis, blue lines on
gums, pain and numbness in extremities, weight loss, mental depression,
and nervousness. Exposure may aggravate kidney disorders, chronic
respiratory disease and nervous system disorders. See Sections 3
and 4 for effects of acute exposure.
Contains mercury.

“WARNING
This dental amalgam product contains mercury. The placement of a
dental amalgam in a patient will increase the levels of mercury
in the body of the patient. The use of a rubber dam may decrease
the amount of mercury absorbed by a patient during the removal or
placement of an amalgam.
The health authorities of the various countries including Canada,
Germany, France, the United Kingdom, Norway and Austria have recommended
against the placement or removal of amalgam in certain individuals
such as pregnant and nursing women and persons with impaired kidney
function.”
