CRITICAL THINKING QUESTION
A woman is scheduled for a full series of radiographs. The dental radiographer is using the XCP
instruments for the series and is prepared to start the procedure. Upon placement of the XCP and
film in the patient’s mouth, the patient appears to be very uncomfortable with the procedure and
removes the XCP and film immediately, stating she is in pain. She says it hurts the roof of her
mouth and she can’t bite down to hold it in place. What adjustments will the dental radiographer
need to make with this radiographic technique?
Discussion Guidelines: The patient appears to have a very shallow palate, which is not a good indicator
