what are the properties?
Also
what do we use it for
white, solid material, insoluble, reactive with strong acids, excellent adhesion properties and corrosion resistance
Used to cement crowns, bridges, ortho appliances and occasionally as a temporary restoration
what are the properties and what do we use it for?
Properties: Silicate and polycarboxylate cements
Used for ORTHO (cementing brackets), restoring areas of erosion near the gingiva, and it can also be used as a liner and dentin bonding agent
properties and its use
low irritancy, great adhesion material, easy to mix, limited mixing time
Usage : cementing permanent crowns, bridges, onlays & inlays, cementing orthodontic bands, also used as a cavity base material under metallic restorations
properties and its use
good insulators, better sealing than zinc phosphate, neutral pH
Usage: filling materials, protective cavity liners, luting materials for crowns, bridges, inlays and orthodontic appliances, root canal fillings, and pulp capping, its also good for soothing a tooth.
Properties of IRM
The eugenol content in the polymer-reinforced zinc oxide-eugenol composition gives the material sedative-like qualities on hypersensitive tooth pulp and is a good thermal insulator as well.
what are the mixing directions and proportions?
Mixed in increments allowing for reduction of reaction rate. Mixing on a cold glass slabs slows down the setting time
how would you clean this up?
scrubbing the instrument manually with a surfactant or detergent and water or by using automated equipment (e.g., ultrasonic cleaner, washer-disinfector) and chemical agents.
mixing proportions and directions
1.5 parts powder to 1 part liquid
Mixing directions: Incorporate powder into liquid in increments being careful not to over mix as it will not set up properly. Polycarboxylate cement set by a fast acid-base reaction
mixing proportions and directions
2 paste system; a powder which consists of Zinc oxide, magnesium oxide, and silica and a liquid that consist of Eugenol, water, acetic acid, zinc acetate, and calcium chloride
85% powder to 15% liquid
why do we use an IRM?
IRMS can help sooth a tooth while they wait for a more permanent solution to whatever issue they are having
how would you cleanup after use?
Cleanup involves alcohol on a 2x2, ensuring that all instruments have been wiped down thoroughly and no cement residue remains
what are the mixing properties and directions?
powder/liquid
You mix this on a cool dry glass slab or on a paper pad manually
NEEDS TO BE HOMOGENEOUS
it also comes premeasured in capsules that go in the amalgamator!
how would you cleanup?
Cleaner containing MDP (Methacryloyloxydecyl dihydrogen phosphate)
How would you cleanup?
organic solvents including alcohol, soap, chloroform, and eucalyptus oil or an ultrasonic removal solution dissolves and removes the temporary cement.
Mixing properties and directions
How would you cleanup?
use floss if on the tooth, if on work station use 2x2 and alcohol to clean off instruments immediately after use as well as disinfectant wipes to clean up your station or op.
Use a spatulation technique that quickly and thoroughly combines 50% of the dispensed powder into all the dispensed liquid. 1.4. 2 Bring the remaining powder into the mix in 2 or 3 increments and spatulate thoroughly.
