Explanation should include the reasons and ways that radiographic exam techniques might be modified to accommodate patient needs, including

• patients who have foreign body objects and/or piercings
• patients with vision, hearing, or mobility impairments
• patients with intellectual and/or developmental disabilities (IDD)
• edentulous, gagging, or pediatric patients. 

Process/Skill Questions:

• What physical disabilities may affect the making of dental radiographs?
• Why should an operator never hold an image receptor?
• How could one modify the technique for partially edentulous patients by using a bite block?
• Why is the exposure sequence especially important when taking x-rays on a patient with a severe gag reflex?
