Any primary or permanent tooth with pits and fissures judged at risk for carieswould benefit from sealant application.. Sealant placement on those teethwith highest risk will give the greatest benefit. High-risk pits and fissuresshould be sealed as soon as possible. Low-risk pits and fissures may not requiresealants.
Caries risk, however, may increase due to changes in patient habits, oral microflora,or physical condition, and unsealed teeth might subsequently benefit from sealantapplication.
Dental sealants are available in an opaque, tinted, or clear form. Tintedand opaque sealants are easier to detect at subsequent dental examinations.
Studies incorporating recall and maintenance have reported sealant success levelsof 80 % to 90 % after 10 or more years. Sealants are easily repaired or replacedif necessary.
