Oklahoma Pit and Fissure Sealants State Practice Exam

What is the leading cause of sealant failure?

1. Improper sealant material

2. Excessive fluoride application

3. Improper sealant placement

4. Inadequate tooth cleaning

The correct answer is: Improper sealant placement

The leading cause of sealant failure is improper sealant placement. This includes factors like inadequate isolation of the tooth during the sealing process, improper application techniques, and failure to achieve a proper bond between the sealant and the tooth surface. If the sealant is not adequately placed, it may not effectively adhere to the tooth, allowing for the penetration of bacteria and subsequent decay. Ensuring proper placement techniques is crucial for achieving a successful and long-lasting seal. This involves proper tooth cleaning to remove debris and saliva, as well as ensuring that the sealant is evenly distributed in the pits and fissures to create a barrier against caries. While other factors, such as the choice of sealant material and fluoride application, may play a role in the overall effectiveness of sealants, the immediate cause of failure often stems from how well the sealant is placed on the tooth surface. This highlights the importance of training and skill in applying sealants effectively.
