DANB Radiology Practice Exam

In the maxillary central region, several key anatomical structures are identifiable during a radiographic evaluation. The nasal septum is a central partition that divides the nasal cavity and is commonly observed in radiographs due to its prominent position. The anterior nasal spine is the bony projection of the maxilla at the base of the nasal cavity and also appears distinctly on radiographs.

The nasal fossa refers to the large cavity of the nasal cavity that lies above the palate and is another important feature visible in this region. The median palatine suture, which is the joining line of the two maxillary bones, is clearly visible as a radiolucent line on radiographs. Lastly, the incisive foramen, located just behind the central incisors, is a key landmark where blood vessels and nerves enter the oral cavity and is identifiable when examining maxillary radiographs.

All of these structures are relevant for diagnostic purposes and help in evaluating conditions related to the maxilla. Understanding these features assists practitioners in interpreting radiographs for various dental and medical applications.
