Comprehensive knowledge about the normal anatomy of the root canal system and its variations of the teeth are essential for the clinician as aberrations in number, shape and size are very common. Various diagnostic aids like preoperative radiographs in multiple angulations or the Cone Beam Computed Tomography can help the clinician in location and effective debridement of the root canal system.
