What is the first step in the process of placing fissure sealants?

• A. The sealant is applied directly
• B. The tooth is thoroughly cleaned and prepared with acid etch
• C. The tooth is polished to a high shine
• D. The cavity is filled with resin

Answer: (B)

The first step in the process of placing fissure sealants is to thoroughly clean and prepare the tooth with acid etch. This preparation is crucial because it ensures that the surface of the tooth is optimal for the sealant to bond effectively. The acid etching process creates micro-roughness on the enamel surface, enhancing the mechanical retention of the sealant material. By removing any debris, plaque, and unwanted contaminants from the tooth surface, and then etching it, the dental professional sets a solid foundation for the sealant application. This preparatory step significantly increases the likelihood of a lasting sealant bond, thus helping to prevent decay in the pits and fissures of the tooth, which are often susceptible to caries. The other choices either imply steps that occur later in the process or do not contribute to effective bonding, making them inappropriate as the first step in placing fissure sealants.
