Oral Surg Oral Med Oral Pathol Oral Radiol Endod. 2009 Jan;107(1):e43-6. doi: 10.1016/j.tripleo.2008.09.006.


Understanding root canal morphology is one of the most important steps in successful root canal treatment. Thus, during the diagnosis and treatment phases of the maxillary molars, a clinician must be aware that anatomical variations exist. A number of studies, especially in vitro, have investigated various root canal morphologies, including aberrations of maxillary molars. This clinical case report highlights an unusual variant of a maxillary second molar with a third mesiobuccal canal.
