Abstract
Purpose: To compare the 2-year clinical performance of an experimental resi n-modified glass ionomer cement sealant (K-512 = Fuji III LC) with that of a light-cured resin-based sealant (Delton Opaque) in young adults: Material s and Methods: 14 subjects with 47 K-512 and 41 Delton sealants were recall ed at 2 years for clinical examination, photographs after enamel etching, i mpressions and radiographs. Results: K-512 showed 0% complete retention, 62 % partial retention, and 38% nil retention. The corresponding percentages f or Delton were 32%, 58% and 10%, respectively. There was one instance of fi ssure caries for K-512 and three for Delton. Sealants deemed to need retrea tments 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 sligh tly darker than the sealed teeth.
