GIC Flashcards
composition of GIC
powder:
Fluoro-alumino-silicate glass
liquid:
poly-acrylic acid
indication of GIC
1 Class Il and V carious cavities.
2. Subgingival Cavities and Sandwich technique.
3. Cervicalnon-cariouslesions.
4. Root caries.
5. Pit and fissure sealant material.
6. Luting cement.
7. Liner/base.
8. Core build-up.
9. Minor repair of restorations and crowns.
10. Temporary restoration
11. Caries Control restorations
12. Atraumatic Restorative Treatment
Caries Control restorations:
Patients with multiple carious lesions.
* Poor oral hygiene and high caries index.
* Intermediate step, until the reason behind this
condition is dealt with.
GIC restorations are highly recommended in patients with:
1 High caries index and bad oral hygiene
2. Low salivary flow
3. Uncooperative patients
4. Medically compromised patients
5. Old-age patients
6. Children.
STEPS OF APPLICATION OF GIC
1 Selection of GIC type
2. Isolation of the operatory field 3. Cavity Preparation
4. Application of liner (if needed) 5. Conditioning of tooth substrate
6. Preformed cervical xiMrtapplication (if needed)
7. Proportioning P: Lratio (If hand mixing wil be done) 8. Mixing of GIC
9. Packing, Finishing and Polishing of GIC
10. Maintenance of water balance through surface protection
during setting of GIC, proper isolation of the operative field from saliva &gingival fluid is?
ESSENTIAL
Finishing of GIC
Finishing and trimming of excess material with sharp blade than re-application of the unfilled resin
polishing of GIC
should be delayed to the next visit or at least 24 hours, or it can be finished after 15
minutes, than re-apply unfilled resin.
polishing of RMGI GIC
RMGI can be finished immediately using diamonds and discs
GIC restoration should be covered immediately
with a’layer of:
*Resin bond
* Varnish
* Vaseline
