Endodotic management of three-rooted maxillary first and second premolars: a case report.

A thorough knowledge of root canal anatomy is essential for successful root canal treatment, because the number of roots and root canals in any tooth can vary. Failing to detect an extra root or canal can cause root canal treatment to fail. It is essential that clinicians interpret radiographs correctly to detect any anatomic variations and treat them successfully.
