Pit and fissure sealants:
1) render pits and fissures more cleansable.
2) arrest incipient caries.
3) mechanically fill the pits and fissures.
4) prevent caries in newly erupted teeth.

Question

Quizplus · Accepted Answer

A pit and fissure sealant is a thin plastic coating of an organic polymer (resin) placed in the pits and fissures of teeth. The sealant acts as a physical barrier to oral bacteria and carbohydrates, thereby preventing dental caries. The sealant bonds mainly by mechanical retention to the enamel tooth surface, forming a protective layer so that caries-producing bacteria cannot colonize within pits and fissures.
