Correct choice. As the fragment wasn't found and the there is a lip laceration it is important to take a soft tissue view to ensure there aren't fragments in the lip. Fragments embedded in the lip are most easily removed in the first 24 hours following injury. This soft tissue view shows some debris on the surface of the lip. A periapical of the injured tooth and the adjacent teeth is required to provide baseline information. An upper standard occlusal radiograph may be helpful if a root fracture is suspected (e.g. where the tooth is mobile).
