CRITICAL THINKING QUESTIONS
1. You are teaching the new dental radiographer in your dental office how to take occlusal images.
What important items must you remember to tell her?
Discussion Guidelines: After completion of infection control procedures and preparation of the
treatment area and supplies, the patient should be seated. After seating the patient and before exposing
2. How would you provide instructions to the new assistant when taking an image for the
maxillary second molar using the buccal object rule and when determining the position of a
radiopaque object using the right-angle technique?
Discussion Guidelines: Before exposing localization images, infection control procedures must be
carried out. In addition, patient and equipment preparations must be completed. The buccal object rule
