To prevent the cement from:
- Dehydration of cement, which prevents
- Cracking of cement, which avoids,
- Discoloration of cement
Additional note:
- Since GIC is a water based cement, it is sensitive to water so exposing the GIC is also unwise in the sense that it might get contaminated with water, hence over-hydrating the cement and affecting its physical properties
- Note that the varnish is applied during the initial phases of GIC setting reaction to allow it to set comfortably, which means right after placement and before polishing
- Also note that some authors say that the polishing burs or any instruments that will be used for instrumentation on GIC should be applied vaseline on their working ends
The mixing pad for Glass Ionomer Cement (GIC) is typically made of a plastic material such as polyethylene or coated paper that is non-reactive with the cement to prevent any unwanted interactions that could affect the setting properties of the GIC.
The folding motion in Glass Ionomer Cement (GIC) application is used to remove excess material and to ensure proper adaptation of the cement to the tooth surface. This motion helps create a homogenous mix and reduces air entrapment, improving the mechanical properties and bond strength of the cement.
Applying Vaseline over glass ionomer cement (GIC) helps protect it from moisture and saliva contamination during setting. The Vaseline forms a barrier that prevents interference with the cement's setting reaction, ensuring better adhesion and longevity of the restoration.
The color change observed when mixing GIC with a steel spatula is due to a chemical reaction between the glass ionomer cement (GIC) and the steel spatula. The metal ions from the spatula can react with the components of the GIC, causing a discoloration or a gray streaking effect. This reaction can compromise the setting properties and aesthetics of the GIC mixture. It is recommended to use non-metallic instruments when handling GIC to avoid such color changes.
Place a protective covering of cocoa butter or varnish or petroleum over silicate or GIC restoration to prevent dehydration :)
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.
GIC : Grand Invalide Civil
The population of Gic is 505.
Mixing Glass Ionomer Cement (GIC) with a plastic spatula is recommended to prevent contamination and preserve the material's properties. Metal spatulas can react with the acidic components of GIC, potentially compromising its setting and adhesion qualities. Additionally, a plastic spatula allows for a more thorough and even mixing of the components, ensuring optimal performance when applied.

The area of Gic is 19.68 square kilometers.
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.
