2. INDICATION FOR USE

Dispersalloy

Amalgam is designed for use in stress bearing restorations (Class 1 and 2), when other restorative

materials or restoration techniques are not indicated.

3. CONTRAINDICATION

The use of amalgam is contraindicated in patients with known allergies to amalgams or any of the components.

4. WARNINGS

1. It has been suggested by the Ad-hoc working group established by the European Commission that the

following information, be kept in mind when considering the use of dental amalgams:

• After placement or removal of dental amalgam restorations increased mercury concentration in blood and

urine has been observed. According to available scientific knowledge this increase has not been associated
with any adverse health effects.

• If placed in close contact with other metal restorations galvanic effects may occur. In most cases they will be of

short lasting duration. If the effect persists the user should consider replacement of the dental amalgam filling with
another material.

• There are no proven adverse effects on the fetus associated with the placement or presence of dental amalgam

fillings in the mother. It is sensible, however, where clinically feasible, to minimize health interventions during
pregnancy and avoid any unnecessary chemical exposure of the fetus. This precaution should be observed with
the use of all dental materials.

• It has also been recommended by certain regulatory authorities that consideration be given to the use of amalgam

fillings in children and that amalgams not be used in patients with severe renal disease.

2. Health Canada Warnings:

• Non-mercury filling materials should be considered for restoring the primary teeth of children where the

mechanical properties of the material are suitable.

• Whenever possible, amalgam fillings should not be placed in or removed from the teeth of pregnant women.
• Amalgam should not be placed in patients with impaired kidney function.
• In placing and removing amalgam fillings, dentists should use techniques and equipment to minimize the

exposure of the patient and the dentist to mercury vapor and to prevent amalgam waste from being flushed into
municipal sewage systems.

• Dentists should advise individuals who may have allergic hypersensitivity to mercury to avoid the use of

amalgam. In patients who have developed hypersensitivity to amalgam, existing amalgam restorations should be
replaced with another material where this is recommended by a physician.

3. Alloy amalgam capsule products contain mercury, which can cause skin sensitization or other allergic reaction.

Although the mercury in this product is bound within the amalgam following trituration, proper care should be taken
to prevent exposure to mercury.

Skin Contact:

Before using this product wear protective safety glasses, clothing and gloves. If contact with skin

occurs immediately wipe off and flush with generous amounts of water, then wash well with soap and water after
contact. If skin rash, irritation, sensitization or other allergic reaction occurs, discontinue use and seek medical
attention immediately.

Eye Contact:

May be irritating to eyes. Before using this product wear protective glasses as well as covering the

patient’s eyes to protect from excess. The use of an enclosed amalgamator is recommended. In case of accidental
contact with eyes, rinse eyes immediately with plenty of water and seek medical attention.

Ingestion:

Do not swallow or take internally. Whenever possible, the use of protective

barriers such as rubber dam isolation and protective mask during placement and removal is recommended. If
accidental swallowing occurs, drink lots of water. If nausea or illness develop, seek medical attention immediately.
Contact regional Poison Control Center immediately.

Inhalation:

Do not breathe vapor. Whenever possible, the use of protective barriers such as rubber dam isolation,

high-volume evacuation and protective mask during placement and removal is recommended. Give oxygen or
artificial respiration if necessary.

4. Do not open capsule prior to trituration. Do not remove or handle mixing pestle or plastic wafer containing mercury.
5. Do not attempt to clean and/or reuse capsules.
6. THIS ALLOY CONTAINS ZINC; AMALGAM MADE THEREFROM MAY SHOW EXCESSIVE EXPANSION IF

MOISTURE IS INTRODUCED DURING MIXING AND CONDENSING.

5. PRECAUTIONS

1. This product is intended to be used only as specifically outlined in the

Directions for Use.

Any use of this product

inconsistent with the

Directions for Use

is at the discretion and sole responsibility of the practitioner.

2. Wear suitable protective eyewear, clothing, mask and gloves. Protective eyewear, and whenever possible, barrier

techniques such as rubber dam is recommended for patients.

(See Warnings)

3. Mercury corrodes and embrittles particular metals and their alloys. Avoid unnecessary contact between mercury

and metals.

4. Mercury presents a health hazard if incorrectly handled. Mercury is toxic by vapor inhalation and the effect is

cumulative. Spillages of mercury should be removed immediately, including places which are difficult to access. Use
a plastic syringe to draw it up. Smaller quantities can be covered by sulfur powder and removed. Avoid inhalation of
the vapor.

5. Regulations for disposal must be observed. Adherence to the American Dental Association’s current “Best

Management Practices For Amalgam Waste (BMPs)” and “Dental Mercury Hygiene Recommendations” is strongly
recommended. Among these practices:
• Salvage and store non-contact amalgam scrap in well-sealed containers and recycle.
• Salvage and store contact amalgam pieces from restorations, traps and filters in well-sealed containers and

recycle.

• Do not dispose of amalgam scrap, waste or extracted teeth in regulated infectious waste containers that will be

incinerated, or in regular garbage.

• Recycle used disposable amalgam capsules and plastic wafer (which contained mercury before mixing).

6. Waste material and all primary containers that hold mercury must be disposed of as hazardous waste.
7. DISPERSALLOY

AMALGAM CONTAINS ZINC; If moisture is introduced into the amalgam before it has set,

properties such as strength and corrosion resistance may be affected adversely. If the alloy contains zinc, such
contamination may result in an excessive expansion (delayed expansion). Whenever it is possible, use a dry field.

8. Manufacturer’s variation in amalgamators and differences in local electrical current may necessitate adjusting

trituration time to obtain an optimal mix.

9. Insufficient data exist to support the use of amalgamators not listed in the chart below. Use of amalgamators other

than those listed may result in less than optimally triturated amalgam. The operator must investigate non-listed
equipment compatibility and/or consult amalgamator manufacturer for recommendations.

10. Do not attempt to place improperly triturated amalgam, or amalgam that has exceeded working time (dry, crumbly).
11. Drilling, polishing and grinding dental fillings should always be combined with water-cooling and suction under a

vacuum.

12. The following precautions are required by the General Director AFSSAPS (Agence française de sécuité sanitaire

des produits de santé – French agency for Sanitary Security of Health Products):
• Store amalgam capsules in a cool and ventilated space.
• Work in ventilated rooms with decontaminable non-textile surfaces.
• Realize shaping and polishing of amalgam always under cooling and suction of the operation field.
• Condense amalgam with classical methods (plugger) and do not use ultrasound condensers.
• Do not place amalgam in direct proximity of other metallic restorations in order to avoid all risk of corrosion.
• Avoid placing and removing amalgam during pregnancy and lactation.
• If local reactions, in particular lichoid lesions in the proximity of amalgam, occur, it is justified to remove the filling.

6. STORAGE

Dispersalloy

Amalgam in Self-Activating Capsules should be stored in a well ventilated place at temperature not to

(See Warnings)

8. STEP-BY-STEP INSTRUCTIONS

Treatment of the preparation:

Clean freshly instrumented enamel and dentin with water spray and then air dry. The

use of pulpal protection, bases and/or cavity liners is at the discretion of the operator, as dictated by the clinical
presentation. If desired, Dispersalloy

Amalgam may be placed over an adhesive liner or adhesively bonded by

following the manufacturer’s instructions for compatible adhesive systems (available separately).

Trituration:

Simply place Dispersalloy

Self-Activating Capsules in the amalgamator. These capsules are activated

by the amalgamator – they do not require manual activation. Trituration speed and time is an important factor in
preparing the amalgam, in order to achieve proper amalgam mix consistency. The chart that follows provides
guidelines in determining amalgamator trituration time and speed setting for Dispersalloy

Suggestions for obtaining optimum mix

2.1 The triturated amalgam should be bright and have a plastic consistency. If the amalgam is excessively splashy

and wet looking, INCREASE trituration time or amalgamator speed. Amalgam that appears excessively dry
indicates trituration time or amalgamator speed should be DECREASED.

2.2 When performing adjustments, it is recommended to adjust trituration time in 2 second increments, until

optimum mix is obtained. Greater adjustments may indicate
amalgamator incompatibility or compromised functionality.
Decrease trituration time:

Increase trituration time:

- To lengthen working time

- To shorten working time

- If mix is too hot

- If mix is too wet

- If mix is too dry

2.3 Properly triturated Dispersalloy

Amalgam does not require mulling to produce a smooth plasticity; however

you may mull for 1-2 seconds after removing pestle to
collect amalgam into a single mass.

Condensation

3.1 No tool is needed to open the Self-Activating capsule. Just grasp both ends of the capsule, twist, and pull apart.

Turn the opened capsule upside down to drop the amalgam mass into the work area. Dispersalloy

Amalgam

is now ready for immediate placement and condensation. A gentle tap may be required to free amalgam from
the capsule. Do not attempt to manually express mercury from the triturated mass prior to placement.

3.2 A plastic wafer and/or plastic mixing pestle may be seen. These have no further function and should be

properly recycled.

0120

3.3 Condense immediately after mix is completed. Use a clean amalgam carrier to transfer increments to the

cavity. Pack each increment into angles and undercuts with small-faced plugger and sufficient pressure to
insure good adaptation. Build the restoration with additional portions, until the cavity is slightly overfilled.
Remove any mercury-rich amalgam from the surface that may develop during condensation.

Carving/Burnishing:

Carving can begin immediately after condensation. A sharp carver will give best results. The

anatomy should be carved proceeding from the proximal margins towards the center of the restoration. Before the
matrix band is removed, the marginal ridge should be supported by a condenser. After removal of the matrix band,
gingival margins may be smoothed with a curved explorer. Burnishing setting amalgam is recommended to improve
surface smoothness.

Polishing:

The quality of the Dispersalloy

Amalgam restoration will be enhanced by polishing. The amalgam should

be allowed to set 24 to 48 hours before polishing. See selected polishing instrument manufacturer’s directions for use.
