How many x-rays are in an FMX?

• A. 12
• B. 18
• C. 20
• D. 22

Answer: (B)

FMX stands for full-mouth radiographic series, which is planned to give a complete view of the teeth and surrounding bone. The standard approach uses 14 periapical radiographs to capture all teeth in both arches from crown to root and the supporting bone, plus 4 bitewing images that focus on the crowns and interproximal spaces to check for interproximal caries and bone level changes. Add these together and you get 18 images in total. This combination provides both detailed tooth-root information and broader interproximal/bone assessment required for a comprehensive diagnostic picture. Some scenarios may adjust the number (for example, excluding third molars or tailoring to a patient’s needs), but 18 is the commonly taught total for an FMX.
