Which is the correct sequence for placing sealants?

The correct sequence for placing sealants begins with cleaning the tooth surface. This step is crucial because it removes any debris, plaque, or saliva that may interfere with the bonding process of the sealant material. After the surface is thoroughly cleaned, the next step is to isolate the tooth. This involves using cotton rolls or other isolation techniques to keep the area dry and free from moisture, which is essential for the effectiveness of the etching process. Finally, the etching step follows, where an acid solution is applied to prepare the enamel surface, creating micro-porosities that will enhance the bond between the sealant and the tooth.

This sequence ensures that the sealant adheres properly and provides effective protection against decay, making it an essential protocol in preventive dental care.
