Does a sinus tract located at the level of tooth 6 necessarily originate from that tooth?

Tracing the sinus tract with gutta-percha and taking a radiograph is very important for diagnosis. Some patients experience pain during tracing, so the gutta-percha cannot be advanced sufficiently. In such cases the radiograph may point to the wrong tooth. A tracing radiograph should then be taken under anesthesia, or the patient can be referred for tomography.
