Oklahoma Pit and Fissure Sealants State Practice Exam

What does microabrasion achieve during the sealant placement procedure?

1. Improves tooth color

2. Removes plaque

3. Opens fissures and slight decay removal

4. Increases sensitivity

The correct answer is: Opens fissures and slight decay removal

Microabrasion is a technique used before the application of pit and fissure sealants to enhance their effectiveness. This procedure involves using a combination of mild abrasives and a gentle abrasion method to remove surface stains or enamel irregularities. One of its primary achievements during sealant placement is to open fissures and enable slight decay removal. This is critical because it allows for better adhesion of the sealant to the tooth surface. By achieving a more clean and prepared surface, microabrasion ensures that any potential areas of decay can be treated and properly sealed, reducing the risk of future caries. This optimization of the tooth surface not only improves the mechanical retention of the sealant but also enhances its protective qualities against bacteria and food particles. While improving tooth color, plaque removal, or increasing sensitivity could be associated with dental procedures, they do not directly relate to the specific function of microabrasion in the context of sealant placement. The primary goal is to ensure an optimal base for the sealant to adhere to and function effectively, making opening fissures and removing slight decay the most relevant achievement of microabrasion in this context.
