What type of spatula should be for mixing glass ionomer cements?
Agate Spatula
Agate Spatula for Used For Mixing Glass Ionomer Cement.
Why is a plastic spatula used to mix GIC?
Some dental mixing spatulas are made from plastic (used mainly for mixing glass ionomer cement) because stainless steel would react with the material being mixed. Dental cement mixing spatulas are used in the preparation of dental cements for prosthodontics procedures.
Does glass ionomer need bonding agent?
Glass ionomer cement does not require any binding agent when placed in cavities [110]. Glass ionomer cement also does not undergo any shrinkage or micro-leakage; these are chemically set by an acid base reaction. It also releases fluoride, which helps in preventing carious lesions.
What is plastic spatula?
The straight shafted spatulas are most often used for scraping food from the sides of pots, stirring ingredients in curved bowls or folding ingredients into each other. They are generally made of a flexible silicone plastic that can move easily around and form into the shape of bowls, pans, and pots.
Why is stainless steel spatula not used in GIC?
The glass slab should not be below the dew point, as moisture may condense on the slab and changes the acid water balance. Never use stainless steel spatula as it is composed of metals which may react with Glass Ionomer cement .
What is Type 1 glass ionomer cement used for?
Type I glass ionomer cement is used primarily as an adhesive. This type of cement is used to secure various types of dental materials in the mouth, such as crowns, bridges, or false teeth/dental prostheses.
What is Type 2 glass ionomer cement?
Restorative Glass Ionomer Cement Type II is a radiopaque glass powder and organic polymer liquid Application: Glass Ionomer Cement Type II is used for restoration of primary teeth core build up and restoration of class III, V and limited class I cavities.
Why Vaseline is applied over GIC?
Similarly petroleum jelly also impedes the fluoride release, but to a very less extent. We suggest that in situations where the fluoride release property is more important than other properties it is better to coat the GIC with petroleum jelly or leave the restoration without any coating.
Can we mix GIC in glass slab?
According to the results of this study, RMGICs must not be manipulated on glass slabs, because there was a reduction in fluoride release.
How long does glass ionomer take to set?
2–3 min
Glass-ionomers set within 2–3 min from mixing by an acid-base reaction. The first step is a reaction with hydrated protons from the polyacid at basic sites on the surface of the glass particles.
What is the difference between a spatula and a flipper?
As nouns the difference between spatula and flipper is that spatula is a kitchen utensil consisting of a flat surface attached to a long handle, used for turning, lifting or stirring food while flipper is in marine mammals such as whales, a wide flat limb, adapted for swimming.
