title: 2-year clinical performance of a resin-modified glass ionomer sealant.
abstract: OBJECTIVE
  To compare the 2-year clinical performance of an experimental resin-modified glass ionomer cement sealant (K-512 = Fuji III LC) with that of a light-cured resin-based sealant (Delton Opaque) in young adults:
  
  
  METHODS
  14 subjects with 47 K-512 and 41 Delton sealants were recalled at 2 years for clinical examination, photographs after enamel etching, impressions and radiographs.
  
  
  RESULTS
  K-512 showed 0% complete retention, 62% partial retention, and 38% nil retention. The corresponding percentages for Delton were 32%, 58% and 10%, respectively. There was one instance of fissure caries for K-512 and three for Delton. Sealants deemed to need retreatments because of retention failures were 62% for K-512 and 34% for Delton. The K-512 sealants continued to darken over the study, many becoming slightly darker than the sealed teeth.
