There's a big artefact on this radiograph, but right beside it is a nasty tooth root abscess. |
- The root of the canine is usually over the second premolar (a trap for beginners is to aim for the crown, but we can see that - we really want to be aiming for the root).
- If you want to split the roots on the radiograph (for example, the carnassial or fourth premolar), use a horizontal oblique view.
- Anatomical structures such as the mandibular foramen can be superimposed over a mandibular tooth root giving the impression of a periapical abscess. If in doubt take a horizontal oblique view.
