What is a common strategy to reduce patient motion during dental radiography?

• A. Increasing exposure time.
• B. Proper stabilization, clear instructions, use of bite blocks, and faster sensors with shorter exposure times.
• C. Reducing shielding.
• D. Performing technique to the maxillary arch only.

Answer: (B)

Minimizing patient movement is essential to obtain sharp dental radiographs. The best strategy combines physical stabilization, clear instructions, the use of bite blocks, and faster sensors with shorter exposure times. Stabilization helps keep the head and jaws steady; clear, simple instructions reduce voluntary movement during the exposure; bite blocks help the patient maintain a consistent bite and reduce jaw motion; and faster sensors allow for shorter exposure times, narrowing the window in which motion can blur the image. This combination lowers the chance of motion artifacts more effectively than any single measure. Increasing exposure time would actually increase the opportunity for movement to blur the image. Reducing shielding is not relevant to motion control and has safety implications. Focusing technique on only the maxillary arch doesn’t address motion across the entire mouth and misses the broader prevention strategy.
