Dental sealant

Dental sealants (also termed pit and fissure sealants,[1] or simply fissure sealants)[2] are a dental treatment intended to prevent tooth decay.[3][4] Teeth have recesses on their biting surfaces; the back teeth have fissures (grooves) and some front teeth have cingulum pits.[5][6][7] It is these pits and fissures that are most vulnerable to tooth decay because food and bacteria stick in them and because they are hard-to-clean areas. Dental sealants are materials placed in these pits and fissures to fill them in, creating a smooth surface which is easy to clean. Dental sealants are mainly used in children who are at higher risk of tooth decay, and are usually placed as soon as the adult molar teeth come through.

Most of the detected increment in dental caries among children above the age of six years and adolescents is confined to occlusal surfaces of posterior permanent molars. Dental sealants and fluoride varnishes are much used to prevent caries.

Sealants are highly effective in reducing the risk of occlusal caries in molars and other teeth with deep pits and fissures.

Sealants are beneficial in high-risk patients and can be used beyond molars, including deep grooves in premolars and lingual pits of incisors.
