Which condition is NOT an indication for sealants?

• A. Lack of pit & fissures
• B. Apparent occlusal decay into dentin
• C. Interproximal decay
• D. Poor patient cooperation in chair

Answer: (A)

Sealants are used to protect the chewing surfaces by filling in clean, deep pits and fissures that are at risk for caries. The key is that there must be actual pits and fissures to seal and the tooth surface must be caries-free so the sealant can bond and stay intact. Lack of pit and fissures means there is nothing to seal, so applying a sealant would not provide any preventive benefit and is therefore not indicated. If there is apparent occlusal decay into dentin, a sealant would not address the existing decay; the tooth needs caries treatment or restoration first, not sealing. Interproximal decay cannot be sealed because sealants cover only the occlusal surface; decay between teeth requires restorative treatment involving proximal surfaces. Poor patient cooperation in chair can complicate isolation and proper sealant placement; while management strategies can help, this situation makes timely and effective sealant application unreliable and is typically considered a limiting factor rather than a straightforward indication for sealing.
