CBCT Diagnosis: Case #2

Patient presented to our office referred by her general dentist for a draining sinus tract adjacent to her previously root canalled tooth. I noticed a draining “pimple” on her check. I asked her about the “pimple” She said she has been treated by her dermatologist for that skin issue for a year now with many rounds of antibiotics. I diagnosed her as having an extra-oral sinus tract secondary to a chronically infected tooth. After the first visit and medicated her tooth with CaOH the “pimple” stared to dry up and heal. After the finishing the root canal the extra-oral sinus tract healed and closed permanently with a small scar.
