evaluation of the clinical and radiographic success of the glass ionomer sealant versus resin sealant in the pits and fissures sealing of the first permanent molars

GIC has a hydrophilic nature which makes it compatible with clinical situations when isolation may be difficult. It also sets rapidly, which can reduce sensitivity to moisture. Glass ionomers release fluoride, which promotes enamel remineralization and has an antimicrobial effect. Another benefit of using glass ionomers as sealants is that the tooth does not need to be etched to achieve chemical bonding to the tooth. Thus saving time which is critical in the case of young patients and patients with disabilities.
