Radiographic Investigation

1. Dental assessment—periapicals, OPG, upper anterior occlusal view.

2. Canines—parallax view with upper anterior occlusal and periapicals / OPG/ lateral skull.

3. Salivary calculi—if radiopaque will show on mandibular occlusal view and OPG. Sialography is the gold standard.

4. TMJ views—High OPG open and closed, also on occasions:

¨              Reverse Towne’s (good for fractures)

¨              CT

¨              MRI

5. Mandibular fractures—OPG, PA mandible, mandibular

             occlusal, reverse Towne’s (for condylar fracture).

6. Facial fractures—Skull X-ray and cervical spine as

             indicated by extent of trauma

¨              Occipitomental 15 and 30

¨              Lateral skull

¨              SMV for possible arch fractures

¨              Upper maxillary occlusal for palatal fracture

¨              OPG to exclude any dental injury

¨              Soft tissue lateral view of nose if indicated

7. Chest X-ray—essential for excluding inhalation of avulsed tooth or restoration.
