In an FMX, the total number of radiographs is...

• A. 18
• B. 16
• C. 20
• D. 24

Answer: (A)

A full-mouth radiographic series combines two types of images to give a complete view: periapical films that show the tooth roots and surrounding bone, and bitewing films that reveal the crowns and the spaces between teeth. In the standard FMX, you would take fourteen periapical radiographs plus four bitewings, for a total of eighteen radiographs. The bitewings are crucial for detecting interproximal caries and assessing bone level in the posterior regions, while the periapicals provide detail on the tooth apices and surrounding bone for the entire dentition. If the protocol were changed, the count would shift, but eighteen is the classic, widely taught total for an FMX.
