The aim of this cross-sectional study was to analyse the preventive need of pit and fissure sealants (PFS) in a German population with a relatively high caries risk. The study involved 311 8- to 12-year-old children from the Ennepe-Ruhr District in North Rhine-Westphalia, Germany. Caries experience was scored according to WHO (1997) and ICDAS II criteria. PFS were assessed as intact or partially lost. The mean DFS values amounted to 0.5 for occlusal fissures, 0.2 for palatal/buccal pits and 0.3 for the remaining teeth. Non-cavitated caries lesions were recorded in average on 1.8 occlusal fissures and 1.5 palatal/buccal pits. Sealants were registered on 1.4 occlusal fissures and 0.4 palatal/buccal pits. The descriptive data and the adjusted Poisson regression models revealed that children with at least one fissure sealant are less likely to have decayed fissures or fissures with non-cavitated lesions on their permanent molars. Therefore, PFS are needed and indicated in caries-risk children.
