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