GI FILL (Regular)
Glass Ionomer Cement Type II
I fill is excellent for restoring cervical erosion areas, root caries, or for other indicated restorative uses. It can also be used as a line in conjunction with a composite restoration. Its index of refraction matches that of tooth structure, preventing the shine-through or mat-white effect resulting from the use of other opaque glass ionomer liners with composites.
The mixing ratio is 1 scoop of powder to 1 drop of liquid (1 : 1), with a minimum of 2 scoops of powder to 2 drops of liquid. For larger mixes, the 1:1 ratio must be maintained.
2.50-2.63gm powder per 1g liquid at 230C and 50% RH
1. Before each use, fluff powder by inverting the bottler several times.
2. Scoop powder from the powder bottle with a measuring scoop, and place a level scoop of powder onto the mixing pad. Repeat for as many scoops of powder as required.
3. Divide powder into 3 equal portions on the mixing pad.
4. To ensure dispensing of uniform-sized drops of the liquid bottle in a vertical position, squeeze the bottle gently and release pressure after each drop separates from the bottle. Any residual liquid on tip of the liquid dispenser should be removed by wiping a damp napkin to prevent clogging of the nozzle.
5. Dispense the required number of liquid drops onto the mixing pad.
6. Using a plastic spatula, incorporate one of the three portions of powder into the liquid. Mix in successive portions until the material reaches a homogenous, composite-like consistency.
7. Mixing should be complete in 30 seconds.
8. Follow appropriate application techniques.
9. Immediately after placement, cover all exposed surfaces of GI FILL with DCL Varnish.
Mixing & Setting Times
(230C and 50% R.H.)
Mix Time – 30 seconds, Working Time – 2 minutes, Initial Setting Time – 4 minutes, Polishable Time – 7 minutes.
Finishing and polishing can be accomplished after 7 minutes.
Mixing on a cold glass slab will prolong working and setting time.
- Excavate decay and for prepare and clean stained area to be restored with pumice or oil-free paste (oil containing formulation or prophy paste will interfere with bonding.)
Note: A rubber dam or retractor should be used to prevent moisture contamination from oral or cervical fluids.
- Place Calcium hydroxide over all pulpal or near pulpal exposure areas only.
- Apply Conditioner (Glass Ionomer Conditioner) or other polyacrlic acid liquid with cotton pledget for 10 seconds.
- If present Acid etches enamel area for one minute: rinse and dry (optional).
- Mix Gi Fill according to instruction.
- Place and contour as required over the previously prepared decayed or eroded areas. this procedure is similar to the use of composites and silicates. Where stainless steel matrix band is used this should be very lightly closed with Vaseline, plastic material strips can also be used. The initial setting time for GI FILLis 4 minutes 30seconds.
- Immediately cover placed GI Fill with glass Ionomer Varnish.
- Wait 10 minutes from the time of placement before finishing and polishing with a fine diamond or other rotary-type instruments.
- Re-cover with Glass Ionomer Varnish.
All stain is removed by polishing with prophy paste and if caries is present, it should be excavated and lined. The conditioner is applied via a cotton pledget for 30 seconds. The cavity is then washed and dried ready to receive the restoration.
The fissures are opened to a depth of 2mm. Remove caries etc. Washed and dry, then carry out fissure filling as normal using the mix recommended over the page.
