Root Canal Treatment of a Maxillary Second Molar with Two Palatal Roots: A Case Report

Knowledge of root canal morphology and variations is an essential factor to successful endodontic treatment. The incidence of a separate second palatal root in a maxillary second molar is very rare. The purpose of this case report is to describe the root canal treatment of a maxillary second molar with 4 separated roots and the variations in the internal anatomy of them, especially their palatal portion. A separate second palatal root was diagnosed in the preoperative radiograph. Careful radiograph examination and change in angulations of radiographs seems necessary for detection of normal variations.
