Infection Control · single question

What is the standard infection control protocol for intraoral digital radiography sensors, which cannot be heat-sterilized?

  1. Single barrier
  2. No barrier needed if the sensor is wiped once after use
  3. Full heat sterilization in an autoclave between patients
  4. Single-use disposable sensors only, with no reusable sensors permitted
Show answer and explanation

Correct answer: A. Single barrier

Because digital radiography sensors are heat- and chemical-sensitive electronic devices that cannot be autoclaved, standard protocol uses a single protective barrier sleeve/cover during use, combined with a 'double wipe' disinfection technique — surface disinfection both before placing the barrier and again after removing it — providing an extra layer of protection against cross-contamination.
