For a comprehensive periodontal and restorative evaluation of a new adult patient, which radiographic series is most appropriate?

A full mouth series (FMX/FMS) — consisting of 14–20 periapical and bitewing radiographs — provides the most complete and diagnostically comprehensive radiographic evaluation for a new patient requiring a comprehensive examination. It allows assessment of all teeth, interproximal bone levels, periapical status, and caries. A panoramic radiograph alone is insufficient for detecting interproximal caries or early bone loss. Bitewings with a panoramic provide a useful combination but are slightly less complete than a full FMX for periodontal assessment. FMX is the standard of care for new adult patients.
