RadiologyWaters view (occipitomental projection) is the best X-ray view for maxillary sinus evaluation. It provides excellent visualization of the maxillary sinuses without superimposition of other structures, allowing assessment of sinus pathology, fluid levels, and bony boundaries.

RadiologyThe coronoid process of the mandible is best visualized on PA view of the skull. This view provides a clear frontal projection of the coronoid process without superimposition of other structures. The coronoid process appears as a triangular radiopacity in this projection.

RadiologyOne advantage of digital radiography is that the radiographic images are obtained immediately.

RadiologyLateral skull view does not clearly show the nasal septum due to superimposition of bilateral structures. While it shows medial wall and root of orbit, nasal bones, and calvarium with sinus roots, the nasal septum is better visualized in anteroposterior projections.

RadiologyA lateral cephalogram is used to assess the level of posterior alveolar bone.

RadiologySubmentovertex view is useful for viewing all mentioned structures: body of mandible (medial displacement), zygomatic arch fractures (excellent visualization), and base of skull fractures. This projection provides a unique axial perspective of these structures.
