The evidence for the efficacy and cost-effectiveness of sealants in reducing occlusal caries in molar teeth has been highlighted in a number of articles in highly rated journals. The most commonly used sealant material is resin composite. Its caries-preventive effect relies on the sealing of pits and fissures through micro-retention, created through tags after enamel acid etching. However, these are easily destroyed by saliva contamination, which reduces micro-retention and consequently, the caries-preventive effect. Under the generally wet conditions in the oral cavity, Glass Ionomer Cement (GIC) offers an alternative. Owing to its hydrophilic properties, GIC is not as moisture-sensitive as hydrophobic resin. The objective of this quantitative systematic review is to assess the caries occurrence on pits and fissures previously sealed with either high-viscosity glass-ionomer based or resin-based fissure sealants, in fully erupted permanent teeth, with follow-up periods from 24 months.
