What is the current best practice regarding gonadal shielding in dental radiography?

• A. Shielding may be used if it does not obscure anatomy or compromise diagnostic quality; not routinely required in all situations.
• B. Shielding is required for all intraoral radiographs
• C. Gonadal shielding is outdated and never used
• D. Shielding should be used only for female patients

Answer: (A)

In dental radiography, the main goal is to minimize radiation dose through proper technique and equipment settings rather than relying on shielding as a routine precaution. Modern intraoral imaging uses tight collimation, fast image receptors, and filtration, which already keep gonadal exposure very low. Because a lead shield can sometimes obscure anatomy or cause beam misalignment, leading to image degradation or the need for a repeat exposure (which would increase the overall dose), shielding is not routinely applied in all cases. The best practice is to use shielding only if it can be placed so that it does not interfere with the diagnostic area and image quality. It can be considered for radiosensitive patients, such as children, when positioned so the shield remains outside the primary beam and does not cover any part of the anatomy being imaged. If shielding would compromise diagnostic information, it should be omitted to avoid retakes.
