Oklahoma Pit and Fissure Sealants State Practice Exam

What can cause the sealant to fail if not done properly during the application process?

1. Using a bite block

2. Cleaning the tooth surface

3. Protecting the working area

4. All of the above

The correct answer is: All of the above

The failure of sealants during the application process can indeed stem from various factors, all of which contribute to the overall effectiveness of sealant placement. Proper application is crucial to ensure that the sealant adheres effectively and provides the intended protection to the teeth. Using a bite block is essential for controlling the patient's mouth and keeping the working area dry, which affects the application process significantly. If a bite block is not utilized, there can be unwanted movement of the jaw, leading to improper placement or contamination of the sealant material. Cleaning the tooth surface is another critical step. If the tooth surface is not adequately cleaned, remnants of plaque, saliva, or other debris can prevent proper adhesion of the sealant. A clean surface promotes better bonding, ensuring that the sealant remains in place over time. Protecting the working area is also vital. The area needs to be isolated from moisture to prevent contamination that could compromise the effectiveness of the sealant. External factors such as saliva can significantly hinder the sealant's performance. Given that all these steps are integral to successful sealant application, it is clear why the answer is that failure can occur if any of these procedures are not properly executed. Each aspect contributes to ensuring that the sealant adheres correctly and
