title: Six root canals in maxillary first molar.
abstract: In this clinical article we report an unusual anatomy that was detected in a maxillary first molar with 6 root canals. The possibility of 6 root canals in this tooth is quite small; however, it must be taken into account in clinical and radiographic evaluation during endodontic treatment. Many times their presence is noticed only after canal treatment, owing to continuing postoperative discomfort.
