Improve Your Radiographic Technique

“As low as reasonably achievable,” or ALARA, is a critical radiation safety principle, as ionizing radiation can cause biological health risks. Organizations, such as the American Dental Association, American Dental Hygienists’ Association, and American Academy of Pediatric Dentistry, promote ALARA. Evidence-based selection criteria guidelines developed by an expert panel of professionals should be used when making decisions about the type, frequency, and quantity of dental radiographs to be taken for adults, adolescents, and children.

While handheld radiography equipment is ideal for use in situations where wall-mounted dental X-ray devices are not accessible—such as mobile dental clinics and outreach events where dental hygiene practitioners may provide oral hygiene assessment and treatment—the radiographer’s ability to hold the handheld equipment during exposure could provide increased stability for patients with special needs.
