Which practice reduces radiation exposure in dental imaging?

• A. Repeat exposures to improve image quality
• B. Use digital sensors when possible
• C. Use older film processing
• D. Increase voltage and exposure time unnecessarily

Answer: (B)

Using digital sensors when possible reduces radiation exposure because digital receptors need less X-ray radiation to produce a diagnostic image. Their higher sensitivity and wider dynamic range mean you can achieve good image quality at lower exposure settings, which aligns with the principle of keeping exposure as low as reasonably achievable. Additionally, digital images can be enhanced or adjusted without needing to retake the exam, further lowering the need for extra radiation. Repeating exposures to improve image quality adds more radiation, and using older film processing can lead to poorer image quality or inconclusive results that require more imaging. Increasing voltage and exposure time unnecessarily directly raises the dose a patient receives.
