Oklahoma Pit and Fissure Sealants State Practice Exam

What should not be used during the sealant application process due to its potential to create deposits?

1. Hydrogen peroxide

2. Sodium bicarbonate

3. Calcium hydroxide

4. Ethyl alcohol

The correct answer is: Hydrogen peroxide

Hydrogen peroxide should not be used during the sealant application process because it can create undesirable deposits on the tooth surface. When hydrogen peroxide is introduced in this context, it can react and leave behind residues that may interfere with the adhesion of the sealant. This is particularly problematic as sealants need a clean, dry surface to bond effectively to the enamel. Other substances, such as sodium bicarbonate, calcium hydroxide, and ethyl alcohol, do not pose the same issues regarding deposit formation. Sodium bicarbonate is often used for cleaning purposes and doesn’t leave significant residues when dried properly. Calcium hydroxide is also used therapeutically in some dental procedures without known adverse effects on sealant application. Ethyl alcohol, while it may affect hydration status of the tooth, does not typically form deposits that would hinder sealant bonding. Thus, avoiding the use of hydrogen peroxide is crucial to ensure the success and longevity of pit and fissure sealants.
