Oklahoma Pit and Fissure Sealants State Practice Exam

What is used to clean the occlusal surface before the application of sealants?

1. Pumice slurry

2. Chlorhexidine rinse

3. Saline solution

4. Water alone

The correct answer is: Pumice slurry

The use of pumice slurry to clean the occlusal surface before the application of sealants is effective for several reasons. Pumice is an abrasive substance that helps to remove plaque, debris, and any surface contaminants from the tooth structure. This cleaning step is crucial because it ensures that the surface is adequately prepared, allowing for a better bond between the sealant material and the tooth. Proper cleaning with pumice slurry enhances the effectiveness of the etching process that typically follows, facilitating a stronger and more durable adhesion of the sealant. By ensuring that the surface is free of oils, saliva, and other potential barriers to adhesion, dental professionals can promote optimal sealant retention and efficacy in preventing caries development in pits and fissures of the teeth. While other options like chlorhexidine rinse, saline solution, or water alone might assist in cleaning to some extent, they do not provide the same level of abrasion needed to thoroughly prepare the occlusal surface for sealant application. Therefore, pumice slurry is the preferred choice to achieve the best possible outcome in dental sealant placement.
