Endodontic Treatment: Case #2 -Patient referred due to pain in her upper first pre molar tooth # 4

This case was interesting because the maxillary first premolar usually has 2 canals 90% of the times, 1 canal 7% of the times and 3 canals 3% of the times. It seems to be more prevalent in patients of African ancestry but can occur in patients of all ethnic backgrounds. The shapes of the tooth is like a small maxillary molar with an MB, DB and Palatal canal. The tooth was completed with a core build-up of composite resin.
