  • Title: On the retention and effectiveness of fissure sealant in permanent molars after 15-20 years: a cohort study.
    Author: Wendt LK, Koch G, Birkhed D.
    Journal: Community Dent Oral Epidemiol; 2001 Aug; 29(4):302-7. PubMed ID: 11515645.
    Abstract:
    The aim of the present study was to clinically evaluate fissure sealants on the occlusal fissures and buccal pits of permanent first and second molars after 20 and 15 years, respectively. The population consisted of 72 children, each of whom had had their four first molars sealed between 1977 and 1980. At the annual examinations, all caries-free, newly erupted second molars were sealed. When sealant was applied to the second molars, the first molars were checked and sealant was reapplied to those that had deficient sealants. At the follow-up, when the subjects were 26-27 years of age, 27 in the original group had moved from the community. Thus, the present result is based on 45 subjects. One hundred and fifty-three sealed first molars and 161 sealed second molars were available for inspection. At the follow-up examination of the first molars 20 years after sealant had been applied, 65% showed complete retention, 22% partial retention without caries, and 13% caries or restoration in the occlusal fissures or buccal pits. At the 15-year follow-up of the second molars, the corresponding figures were 65%, 30%, and 5%, respectively. Of the restored or carious molars, significantly more were found in the mandible than in the maxilla (P<0.001). This longitudinal study showed that pit and fissure sealants--applied during childhood--have a longlasting, caries-preventive effect.
