What instrument is typically used to remove cement remnants from a tooth after band removal?

1. Scaler

2. Ultrasonic

3. Forceps

4. Explorer

The correct answer is: Ultrasonic

The typical instrument used to remove cement remnants from a tooth after band removal is the ultrasonic scaler. This device uses high-frequency vibrations to effectively break down and dislodge materials such as cement and plaque from the tooth surfaces without damaging the dental enamel. The ultrasonic scaler is particularly useful because it combines mechanical action with a water spray that helps to wash away debris and provides a cooling effect, making the process more efficient and comfortable for the patient. While the other instruments have their specific uses in dentistry, they are not primarily designed for this particular task. A scaler is mainly utilized for removing calculus from tooth surfaces, forceps are typically used for extracting teeth, and an explorer is designed for examining tooth surfaces for decay and defects. Therefore, the ultrasonic scaler stands out as the most appropriate choice for cleaning up after band removal.
