What are the indications and contraindications for the use of Glass ionomer cements
I have provided a brief note on the indications and the contraindications for the usage of GIC.
Indications:
Restorative Materials:
Restoration of erosive/abrasive lesions without cavity preparation.
Sealing and filling of occlusal pit and fissures.
Restoration of primary teeth.
Restoration of Class V carious lesions.
Restoration of Class III carious lesions, preferably using lingual approach.
Repair of defective margins in restorations.
Minimal cavity preparations in a proximal lesions through buccal and occlusal approach (tunnel preparations).
Core built up.
Provisional restorations where future veneer crowns are contemplated.
Sealing at root surface for over dentures.
Fast Setting Lining Cements and Bases:
Lining of all types of cavities where a biological seal and cariostatic action are required.
Replacement of carious dentin for the attachment of composite resins using the acid etch technique.
Sealing and filling of occlusal tissue showing early signs of caries.
Luting Cements:
Fine grain versions of the glass Ionomer cement are now available for luting purpose because of their fluoride leach, these cements are particularly useful in patients with high caries incidence. In addition, the translucency of the glass Ionomer cement is of great value where porcelain margins are used for cosmetic reasons.
Contraindications for Use:
1) Class IV carious lesions (or) fractured incisors
2) Lesions involving large areas of labial enamel where esthetics is of major importance.
3) Class II carious lesion where conventional cavities are prepared, for replacement of existing amalgam restorations.
4) Lost cusp areas.
