Orthodontic Assistant Practice Exam

Prior to the cementation of orthodontic bands, which step is essential?

1. Teeth are polished and dried

2. Patient records are reviewed

3. X-rays are taken

4. Teeth are extracted

The correct answer is: Teeth are polished and dried

Before the cementation of orthodontic bands, it is essential to polish and dry the teeth. This step is crucial because it helps to remove any plaque, debris, and contaminants from the surface of the teeth, which can interfere with the bonding process of the orthodontic cement. Properly cleaning the teeth allows for better adhesion of the bands, ensuring they remain securely in place throughout treatment. Additionally, drying the teeth helps optimize the bonding environment by minimizing moisture, which can also compromise the effectiveness of the cement. While reviewing patient records, taking X-rays, and extracting teeth may be necessary in the broader context of orthodontic treatment, these steps are not directly related to the immediate process of preparing teeth for band cementation. Polishing and drying get the teeth ready to ensure a successful and lasting bond.
