From 2011-2017, images and videos of "The Root Canal Anatomy Project" were developed at the Laboratory of Endodontics of Ribeirao Preto Dental School - University of Sao Paulo - under supervision of Dr Manoel Sousa Neto. From 2016, images were acquired in other educational institutions. They can be freely used for attributed noncommercial educational purposes by educators, scholars, student and clinicians. It means that all material used should include proper attribution and citation ( In such cases, this information should be linked to the image in a manner compatible with such instructional objectives. Unfortunately, because material shared on the RCAP has not been properly cited by several users, from November 2019 a watermark was added to the images and videos. Enjoy!

MB3 Canal [Maxillary First Molar]

The internal anatomy of the mesiobuccal root (MB) of maxillary molars is complex and commonly presents 2 main root canals, named MB1 and MB2, but also a high incidence of fine anatomical structures, which may include the presence of a 'middle mesial canal', the so-called MB3. MB3 canal can be defined as a third main root canal located in between MB1 and MB2 main canals of the MB root of maxillary molars. Literature regarding morphological description of MB3 canal is scarce and most of the information comes as a clinical report or an incidental finding of laboratorial studies, but not as the main topic of the research. 

More information about this topic in a well-designed micro-CT study is going to be published very soon...
