Glass ionomer fissure sealants

Abstract

Glass ionomer (GI) sealants can be utilised when a resin-based sealant is indicated but cannot be placed due to poor moisture control, resulting from either inadequate tooth eruption or poor patient co-operation. GI is hydrophilic, making it more compatible with the oral environment. Another significant advantage of GI sealants is their action as a fluoride reservoir, aiding in the remineralisation of enamel.
