Which sequence should be performed first when taking a full mouth radiographic survey?

• A. Anterior front first
• B. Posterior first
• C. Bitewings first
• D. Molars first

Answer: (A)

Starting with the anterior front exposures sets you up for a smoother full-mouth survey. Anterior periapicals are quick to take, easier to position, and tend to provoke less gagging, so the patient can become comfortable with the process early on. Establishing good head position and midline reference with these initial images helps ensure the later posterior exposures are accurate and require fewer adjustments. By getting the easier, less uncomfortable images first, you reduce the chance of patient movement or fatigue compromising the more challenging posterior and bitewing images. If you were to begin with posterior or bitewings, the patient might struggle more at the outset, making technique harder and increasing the likelihood of repeats.
