What cleaning materials should be avoided prior to sealant placement?

Fluoride-containing materials should be avoided prior to sealant placement because they can interfere with the bonding process of the sealant to the tooth surface. Sealants require a clean, dry surface for optimal adhesion and the presence of fluoride can create a barrier that inhibits proper bonding. Fluoride may prevent the sealant from adequately penetrating the microscopic pits and fissures of the tooth enamel, which is essential for sealing out decay.

In contrast, other cleaning materials may not present the same issue. Gels, saline solutions, and alcohol-based wipes do not typically interfere with the bonding properties of sealants in the same way fluoride does. While it’s important to ensure that the tooth surface is clean, these alternatives can be effectively used to prepare the tooth without compromising future sealant placement. This understanding is crucial for dental assistants to ensure successful sealant application and long-term effectiveness.
