endomontreal

33mm long mesial canals in a lower left molar, 

30 mm long palatal canal (Legend #1) and another MB2 wich is not merging with MB1.

Intricate endodontic procedure, case study number: 417

A Vertucci type V pulp space configuration can be described as follow: One canal leaves the pulp chamber and divides short of the apex into two separate distinct canals with distinct foramina (1-2). According to Vertucci’s study in 1984 on a 100 mandibular molars sample, the type V configuration in distal root, occured only in 8% of the teeth examined. In the apical third of distal root, each part of the split as been individually cleaned, shaped and filled with Gutta Percha and Pulp Canal Sealer. 

This is a very long tooth, it's position in the arch (second molar), it's sharp curve and it's apical third split in distal root canal, are all factors wich are listed in the high difficulty category of the American Association of Endodontists (A.A.E.) Endodontic Case assessment Form. Thus, this specific case, according to the American Association of Endodontists, present exceptionally complicated preoperative condition, exhibiting several factors listed in the HIGH DIFFICULTY category.

28 mm long sclerotic and curved canals and a type III canal configuration in distal root.
