Mandibular first molar with three distal canals. 1984

W F Stroner, and N A Remeikis, and G B Carr

A mandibular molar requiring root canal therapy was found with five canals, a mesial root, and two distal roots. The distobuccal root had two separate canals, and the distolingual root had but one. The bizarre aspects of this case are somewhat lessened because of the presence of the second distal root. Practitioners should not become excessively alarmed by the increasing reports of bizarre pulpal anatomy. However, knowledge of their existence may occasionally enable them to treat a case successfully that otherwise might have ended in failure.

D008963	Molar	The most posterior teeth on either side of the jaw, totaling eight in the deciduous dentition (2 on each side, upper and lower), and usually 12 in the permanent dentition (three on each side, upper and lower). They are grinding teeth, having large crowns and broad chewing surfaces. (Jablonski, Dictionary of Dentistry, 1992, p821)	Molars

D003786	Dental Pulp Cavity	The space in a tooth bounded by the dentin and containing the dental pulp. The portion of the cavity within the crown of the tooth is the pulp chamber; the portion within the root is the pulp canal or root canal.

D014092	Tooth Root	The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots.
