MODULE 5: CRITICAL THINKING QUESTIONS
1. If you were helping to plan a new practice, which type of imaging system (digital versus film–
based) would you choose and why?
Digital imaging has the following advantages:
• Superior gray-scale resolution.
• Lower equipment and film cost.
Long-term digital imaging eliminates the need for purchasing conventional film, costly
processing equipment, and processing solutions. With digital imaging, darkroom and
processing solutions and maintenance are unnecessary. Also, environmental costs are
reduced because the disposal hazards of processing chemicals, silver salts in film emulsion,

2. A patient in your office needs to be referred for three-dimensional imaging in order to begin her
implant treatment planning. How will you explain the importance of obtaining three-dimensional
imaging in terms the patient can understand?
Three-dimensional imaging provides the dental professional with a more complete
3. Why is it important for dental professionals to learn about anatomy of the skull? Give examples of
how normal anatomy knowledge is needed in everyday practice.
Each normal anatomic landmark seen on a dental image corresponds to what is seen on the
PANORAMIC IMAGES
• Knowledge of normal anatomic landmarks is necessary to interpret panoramic images;
