CBCT Artefact

This patient came in for regular check up and we took a CBCT to do implant treatment planning. As an incidental finding, we found a periapical lesion over the premolar that we felt should be dealt with before any implants were done. The tooth looked fine but that does not mean anything as it could be a fracture or occlusal trauma. Pulp test suggested vital but I have cases where one part was vital and another part was non vital although this is usually in molars.
