Final answer:

Sealants have specific indications and contraindications based on the patient's condition. They are made of resin-based materials and are placed on specific surfaces of teeth to prevent decay.


Explanation:

Indications for sealant use:

  • Prevention of dental caries in the pits and fissures of teeth,
  • Protection for high-risk individuals,
  • Early signs of non-cavitated caries lesions,
  • Patients with poor oral hygiene habits.

Contraindications against sealant use:

  • Cavitated caries lesions,
  • Inadequate isolation and moisture control,
  • Patient non-compliance,
  • Patients with active caries lesions and poor oral hygiene.

#1 reason why a sealant would be contraindicated:

Presence of cavitated caries lesions.

Sealants are made of resin-based materials similar to composite fillings but without the added amalgam present in composite fillings. Light-cured sealants utilize a curing light to harden the material whereas self-cured sealants undergo a chemical reaction to set.

Teeth surfaces where sealants are placed: Sealants are typically placed on the occlusal surfaces of molars and premolars, specifically in the pits and fissures, to prevent decay in these susceptible areas.
