Which is the most appropriate step to help a young patient who cannot stay still during radiographs?

• A. Use a bite-block to stabilize
• B. Administer sedation
• C. Have the parent hold the child without shielding
• D. Use a larger exposure factor

Answer: (A)

Minimizing movement is crucial for obtaining clear radiographic images, especially in young patients who may find it hard to stay still. A bite-block provides a simple, effective stabilization aid by giving the child a small, comfortable surface to bite on, which helps lock the jaw in place and reduces overall head motion during the exposure. This noninvasive approach improves image sharpness and lowers the need for retakes without introducing additional risks.

Sedation is more invasive, carries medical risks, and is not routinely used for routine pediatric radiographs. Having a parent hold the child without shielding exposes both the child and the parent to radiation and ignores protective guidelines. Increasing the exposure factor would raise the dose without addressing motion, potentially compromising safety and still not prevent blur from movement.

Using a bite-block strikes the right balance of safety, practicality, and image quality, making it the most appropriate first-step to help a young patient stay still during radiographs.
