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
What else can I help you with?
Which material is used for making mixing pad of GIC?
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.
Why folding motion is used for 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.
Why vaseline is applied over gic?
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.
Why gic colour changes when mixed with steel spatula?
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.
Use of cocoa butter in silicate restoration?
Place a protective covering of cocoa butter or varnish or petroleum over silicate or GIC restoration to prevent dehydration :)
Why agate spatula is used in glass ionomer cements?
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.
