Orthodontic Assistant Practice Exam

When seating a band, which part must you be cautious with when placing the metal part of the bite stick?

1. Cervical margin

2. Buccal enamel

3. Occlusal enamel

4. Pulp chamber

The correct answer is: Occlusal enamel

The correct answer highlights the need for caution at the occlusal enamel when seating a band. The occlusal enamel is the top or biting surface of the tooth where it interacts with opposing teeth. When applying pressure with the bite stick, if excessive force is exerted on this area, it can potentially lead to harm, such as chipping or fracturing the enamel. Additionally, there’s a risk of causing discomfort to the patient or disrupting the tooth's position if the force is applied incorrectly. Proper care in this area ensures the longevity of the band seal and helps maintain overall dental health. Other areas such as the cervical margin and buccal enamel are also important to consider, but the occlusal surface is the focus in this scenario due to its direct involvement in the band seating process and potential for damage if not handled properly. The pulp chamber, while critical in determining tooth health, is not relevant in the direct context of band seating with a bite stick.
