– The aim of this study was to compare the retention and caries preventive efficacy of glass ionomer (Fuji III; GIC) and light‐cured resin‐based (Delton; LCR) fissure sealants. One hundred and sixty‐six 5–14‐year‐old schoolchildren received sealants on their newly erupted first or second molars; a split mouth design was used. Previously reported 2‐year results showed low retention rates for GIC sealants, but no difference in the caries increment between the groups. The same persons were invited to a dental check‐up 6.1 to 7.8 (mean 7.1) years after the application of sealants; 111 persons (66.8% of the original group) participated in the study. The retention of sealants, and the caries status of occlusal surfaces and adjacent proximal surfaces was recorded. On the sealed occlusal surfaces, 10% of GIC and 45% of LCR sealants were totally and 9% of GIC and 20% of LCR sealants partially present. Twenty‐three (23.5%) of the occlusal surfaces sealed with GIC and 16 (16.5%) of those sealed with LCR were carious or filled. Compared to LCR sealants, the effectiveness of GIC sealants was –44% (95% CI –71%, 16%) and net gain –7% (95% CI –18%, 4%). The relative risk of caries occurring was –44 (95% CI 0.96, 2.14).
