Abstract
AIM: The purpose of the study was to determine the retention of glassionomer sealants in primary teeth of preschool children. METHODS:Fissure sealants (Fuji II LC) were placed on primary molars, without conditioner, by two experienced dentists under good clinical conditions in well equipped clinics and with the assistance of a chair side dental assistant. Sealants were scored as "fully retained", "partly retained", or "completely lost" after two years. RESULTS: There were 65 children included, out of which 29 had all primary molars. Mean age at the time of sealing was slightly less than 41/2 years. Mean follow-up time was two years. About 75% of the sealants placed in second primary molars were fully or partly retained after 12 months, compared with less that 50% of the sealants placed in first primary molars. New carious lesions were too few to allow for an assessment of whether the sealants were effective in preventing caries. CONCLUSION:Retention rates for glass ionomer fissure sealants were satisfactory. However, high quality randomised clinical trials to estimate the caries preventive effect are still needed.
