A Sealant is best described as?

• A. A coating applied to the biting surface to prevent decay
• B. A fixed or removable appliance
• C. A tooth whitening agent
• D. A root canal procedure

Answer: (A)

Sealants are thin resin coatings placed on the chewing surfaces of teeth to seal pits and fissures and prevent decay by creating a protective barrier. This is why the description “a coating applied to the biting surface to prevent decay” is the best fit—it focuses on how sealants function to block plaque and bacteria from entering deep grooves. They’re applied after cleaning and etching the enamel to help the material bond, then cured with a light. Sealants are not an appliance, not a whitening agent, and not a root canal procedure, which is why those options don’t describe their purpose. They can be resealed if they wear or chip, helping maintain long-term protection against occlusal caries.
