What is the coating that covers the occlusal pits and fissures of teeth?

• A. Sealant
• B. Disclosing Agent
• C. Pontic
• D. Amalgam

Answer: (A)

Dental sealants are a protective coating applied to the chewing surfaces of back teeth to seal the deep pits and fissures. This thin plastic layer fills in the grooves so food and bacteria can’t get trapped there, which helps prevent tooth decay. Sealants are commonly placed on newly erupted permanent teeth, especially in kids and teens, and they cure to form a durable barrier on the enamel. Disclosing agents are used to reveal plaque by staining it for teaching brushing technique, not to protect pits and fissures. A pontic is a false tooth in a dental bridge, not a coating. Amalgam is a metal filling material used to restore cavities, not a preventive sealant.
