What is the first step in placing dental sealants?

Etch the surface
Cure the sealant
Clean the surface
Apply the sealant

The correct answer is: Clean the surface

The first step in placing dental sealants is to clean the surface. This step is crucial as it ensures that the tooth surface is free of any debris, plaque, or saliva, which can interfere with the adhesion of the sealant. Properly cleaning the tooth allows for the sealant to bond effectively, providing a protective barrier against cavities in the grooves and pits of the teeth. After the surface has been cleaned, the subsequent steps include etching the enamel to enhance the bond, applying the sealant, and finally curing it to set the sealant in place. Each of these steps plays a significant role in the overall effectiveness of the sealant, but cleaning the surface is foundational to ensuring a successful application.
