CRITICAL THINKING QUESTION
A new patient waits outside the radiography operatory when the radiographer is setting up for
use. The patient tells the radiographer, “Isn’t this overkill? This sure does seem like a lot of x–rays
to have taken in one visit.” How might the dental radiographer respond to the patient?
Discussion Guidelines: The dental radiographer must explain the importance of dental radiographs and
