Which restorative material releases MORE fluoride?
Show answer and explanation
Correct answer: B. Conventional glass ionomer (GI)
Conventional Glass Ionomer Cement (GI) releases MORE fluoride than Resin-Modified Glass Ionomer (RMGI). The resin component in RMGI reduces fluoride release compared to conventional GI, which releases fluoride through a sustained acid-base reaction. However, RMGI has superior mechanical properties. The fluoride release hierarchy: GI > RMGI > Compomer > Composite (composite releases negligible fluoride).
