The main concept is that glass ionomer cement combines chemical bonding to tooth structure, fluoride release, moisture tolerance, and a good marginal seal, which makes it especially well suited for pediatric luting and as a base. It chemically bonds to dentin and enamel, providing retention without relying solely on mechanical retention. It continuously releases fluoride, offering an anti-cariogenic benefit that is valuable in children. In the pediatric setting, achieving a perfectly dry field can be difficult, so a material that tolerates some moisture while still setting and sealing well is advantageous. Its ability to seal margins helps reduce microleakage and protects underlying dentin. It’s not the strongest luting material, and it does interact with moisture (it isn’t completely moisture-proof), but its combination of bonding, fluoride release, moisture tolerance, and sealing makes it a versatile choice for both luting restorations and acting as a base.
