Initial interpretation: No initial interpretation as this radiograph was made for an implant in the maxillary canine region and nothing else was evaluated. 🙁
Final Interpretation: Rarefying osteitis at the apex of the maxillary left second premolar with external resorption (most likely due to the presence of a periapical granuloma at some time). Upon reviewing the older radiographs, the rarefying osteitis was evident on radiographs from 2 years prior.
Lesson learned: It is important to remember to evaluate the entire radiograph and not focus on only the area or tooth where treatment is planned. This case is a good reminder that every aspect of every radiograph must be thoroughly evaluated.
If you have any questions about this case, please let me know. Thanks and enjoy!
