Name a normal anatomical variant that can appear on a maxillary anterior radiograph.

• A. Calcified stylohyoid ligament
• B. Septa within the maxillary sinus
• C. Nasopalatine canal (incisive foramen)
• D. Enlarged anterior nasal spine

Answer: (C)

In a maxillary anterior radiograph, a normal variant you should recognize is the nasopalatine canal, seen as the incisive foramen. This midline radiolucent area between the roots of the central incisors represents the canal carrying the nasopalatine nerve and vessels. It often appears as a round to oval space with a thin radiopaque rim and should not be mistaken for pathology, since its location, symmetry, and relation to the tooth roots confirm its benign nature. The other findings listed either do not belong in this view or are less characteristic: a calcified stylohyoid ligament is a skull-base/neck structure not typically seen in the anterior maxilla; a septum within the maxillary sinus is inside the sinus and not a standard feature of an anterior-view radiograph; an enlarged anterior nasal spine can be seen in this region but is less specific and less commonly recognized as a typical normal variant on this specific view.
