Comparative Evaluation of Glass Ionomer and Resin-Based Fissure Sealants on Newly Erupted Permanent First Molars: A 24-Month Randomized Clinical Trial

A high-viscosity, self-curing glass ionomer sealant used for the occlusal surfaces of newly erupted permanent molars. This material releases fluoride and is moisture-tolerant during application. The product used in this study was Fuji Triage™ Capsule (GC Corporation, Japan).

A moisture-tolerant, light-cured resin-based fissure sealant designed for application to occlusal surfaces in partially erupted permanent molars.
