摘要

Dental sealants are clear or opaque plastic materials applied to the pit-and-fissure surfaces of teeth to prevent decay (dental caries). Sealants provide a physical barrier that prevents debris and decay-causing bacteria from collecting in the pits and fissures of vulnerable teeth (mainly molars). These areas are often the first and most frequent sites to be affected by tooth decay in children and adolescents. National estimates show that as much as 90% of all dental caries in school children occurs in pits and fissures. The permanent first and second molars are at the highest risk for tooth decay. To be most effective, sealants should be placed on teeth soon after they erupt. Sealants are helpful for persons at increased risk for tooth decay such as those with medical conditions associated with higher caries rates, children who have experienced extensive caries in their primary teeth, and children who already have incipient caries in a permanent molar tooth.
