PURPOSE: To evaluate the clinical performance of Helioseal-F, a fluoride-containing fissure sealant, in school children at caries risk. MATERIALS AND METHODS: A caries risk assessment based on past caries experience, saliva microbial tests, buffer capacity and frequency of sugar intake was carried out in 204 healthy children, 6-7 years of age. Children exhibiting one or more risk factors were considered at caries risk (n = 121) and their permanent molars were sealed with a fluoride-containing fissure sealant, thus forming a fissure sealant group (FSG). The remaining 83 children with low caries risk received no fissure sealants and constituted a reference group (RG). Both groups were followed for 2 years. From 15 children of both groups, unstimulated whole saliva was collected 1 month after sealant placement in order to determine fluoride levels. In another 20 children, a split-mouth study design was utilized to compare the colonization of mutans streptococci adjacent to and on F-containing sealants and conventional controls. The sealants were placed by dental hygienists according to the manufacturers' instructions. RESULTS: A total of 431 fissure sealants were placed at baseline. Complete retention was found in 76.6% during the study period while 22.0% were partially lost. Six sealants (1.4%) were completely lost. The enamel caries incidence was 45% lower (P
