    Abstract:
    The efficiency of sealing the occlusal fissures of permanent first molars was studied in a group of patients 6-9 yr of age receiving a high standard of prophylactic care. Very soon after the eruption one of the teeth in a homomaxillary pair was sealed, and the contralateral was used for control. The control teeth were painted with a fluoride varnish (Duraphat) every 6 months during the trial. 210 sites in 121 children were sealed and followed for a mean observation period of 23 months. At the end of the study, the retention rate was 62.9%, the percentage of effectiveness 24.2%, and the net gain 7.1%. The dmft index (primary molars and canines) was recorded for each patient at the time sealing was performed. A relationship between the caries prevalence in the primary teeth and the susceptibility for fissure caries in the control teeth was found. Effectiveness and net gain was highest in the group of children with 3-6 dmft.
