Glass ionomer cement should not be mixed on a glass slab because the ions present in the cement can react with the glass slab, leading to contamination and affecting the setting reaction of the cement. This can compromise the physical properties and performance of the cement. It is recommended to use a disposable mixing pad or a mixing paper to prevent any unwanted reactions and ensure the proper setting of the glass ionomer cement.

Glass ionomer cement is known to cause the least irritation to the pulp among dental cements. It releases fluoride, which can help protect the tooth structure and promote remineralization.

Agate spatulas are used for mixing glass ionomer cement because they do not react with the cement ingredients, ensuring that the material remains uncontaminated. This helps to maintain the properties and performance of the cement. Agate spatulas are also non-reactive and do not scratch the glass slab used for mixing, preventing any impurities from entering the mix.
Agate spatulas are used with glass ionomer cements because their non-reactive surface prevents any interference with the setting reaction of the cement. This helps to preserve the properties of the cement and ensures an accurate mix. Agate spatulas also do not scratch or damage the glass slab used for mixing the cement.
The term "agate" refers to the material the spatula is made from, which is a type of rock with distinct banded layers. Agate is used for its smooth and non-reactive surface, making it ideal for mixing glass ionomer cement without causing any unwanted reactions or contamination.
Mixing glass ionomer cement with an agate spatula on a mixing pad helps prevent contamination of the cement from metal ions that could interfere with the setting reaction. Glass ionomer cements are sensitive to contamination, so using non-metallic instruments like an agate spatula and mixing on a pad that won't introduce metal ions ensures the material sets properly and bonds effectively to the tooth structure.
The step of using an adhesive or dentin bonding agent is not taken when loading a crown or bridge with a ZOE or glass ionomer luting cement. These cements have adhesive properties and bond directly to the tooth structure without the need for a separate bonding agent.
It means that it releases a substance. In the case of glass ionomer luting cements, fluoride is luted into the dentin. Also, Aviva is wrong.
