In 13 of these (65%) the third canal joined the mesiobuccal canal in the apical third of the root and in 6 (30%) they converged with the mesiolingual canal, also in the apical third; the third canal ended as an independent canal in only 1 case. Many authors agree on the presence of three foramena in the mesial root but few report three independent canals, which presents itself as a rare anatomical variant. Walker cites 3 canals in the mesial root of the mandibular first molars as an infrequent ocurrence. Goel notes that the mesial root of permanent mandibular first molars presented two foramena in 60% of the specimens they examined, 6,7% had three and 3.3% even had four. In early studies by Hess, onl...

Begun formally in 2011, The Root Canal Anatomy Project  completed two years online on 5th of March. This blog was developed in the Laboratory of Endodontics of Ribeirao Preto Dental School - University of Sao Paulo - with noncommercial and educational purposes. During this period, the blog was visited by people from 163 different countries with more than 221,000 page views . The videos were watched more that 54,000 times and the material was downloaded more than 6,000 times . Considering that root canal anatomy is a very specific subject in the endodontic field, we believe that the blog is achieving its goals. Thank you for your support and stay tuned for updates.
