What surface condition should be achieved before placing sealants?

Before placing sealants, it is crucial to ensure that the tooth surface is clean and dry. A clean surface is essential because it allows for the proper adhesion of the sealant material to the tooth. Any debris, plaque, or saliva can interfere with this bond and lead to sealant failure.

Drying the surface is equally important. A dry environment reduces the risk of moisture contamination, which could compromise the effectiveness of the sealant. Keeping the surface free from moisture also ensures that the sealant can properly penetrate into the grooves and fissures of the tooth, creating a strong seal that effectively prevents cavities.

Selecting a clean and dry surface prepares the tooth for optimal sealant application, promoting longevity and effectiveness in caries prevention.
