Endodontic Retreatment: Case #5 – Retreatment of initial root canal done 30 years earlier.

Problem 7 mm periodontal pocket on the buccal side with slight pain to biting. His general dentist felt that the tooth may be fractured and referred the patient to determine if an extraction is necessary. During examination we determined that there was a missed DL canal that is challenging to locate. This type of tooth is called radix entomolaris and is more common in people of Asian ancestry. The canal was located, treated and the periodontal pocket healed as well as his biting pain.
