An operator who holds a radiographic receptor in a patient's mouth increases the chance of developing which condition?

• A. Carpal tunnel syndrome
• B. Radiation-induced cancer
• C. Thyroid disease
• D. Skin cancer

Answer: (B)

Holding a radiographic receptor in a patient’s mouth increases the operator’s exposure to ionizing radiation. When the receptor is kept in place by the clinician, their hands and sometimes their head or neck are closer to the scattered radiation and even the beam itself, raising the operator’s cumulative radiation dose over time. Radiation-induced cancer is a stochastic effect, meaning the probability of developing cancer grows with the amount of radiation dose received, so any extra exposure to the operator raises long-term cancer risk. That’s why safety guidelines emphasize not holding receptors yourself: use film or sensor holders, positioning aids, or have an assistant while you stand back and behind protective barriers. The situation doesn’t directly relate to conditions like carpal tunnel (musculoskeletal strain from repetitive tasks) or reliably cause thyroid disease or skin cancer in typical dental-dose scenarios, especially when shielding and proper protocols are followed, but the cancer risk from occupational exposure is the most direct and significant concern.
