A field trial of resin-based and glass-ionomer fissure sealants: Clinical and radiographic assessment of caries
OBJECTIVE The purpose of the present study was to provide further data for comparison of retention and caries-preventive effect of a resin-based sealant ( Delton , and a glass-ionomer sealant ( Fuji III ) . METHODS The study was conducted in the municipality of Vaerløse located 15 km north of Copenhagen , Denmark in the period 1996 - 2001 . The study comprised 153 children aged 8 - 13 years with a total of 364 site-pairs . Caries was diagnosed both clinical ly and radiographically , and sealant retention was diagnosed clinical ly . Sealants were placed either by one of four dentists , who had the responsibility for the children 's dental care , by a dental hygienist or a dental assistant . Mean follow-up time was 38 - 39 months for sites on first permanent molars and 28 - 29 months for sites on second permanent molars . RESULTS The retention rates were consistently , and considerably lower for Fuji III than for Delton .  Relative risks of caries in Delton-sealed teeth over Fuji III-sealed teeth was 0.435 ( 95 % CI 0.150 - 0.846 ) based on the clinical diagnosis , and 0.559 ( 95 % CI 0.342 - 0.905 ) based on the radiographic diagnosis . The ratio of the relative risks ( clinical over radiographic diagnosis ) was close to 1 ( 0.778 ; 95 % CI 0.272 - 1.481 ) . CONCLUSION In the present study , Delton-sealed teeth had a lower risk than Fuji III-sealed teeth of developing caries , independent of the caries diagnostic method used
