From 2011-2016, images and videos of "The Root Canal Anatomy Project" were developed at the Laboratory of Endodontics of Ribeirao Preto Dental School. 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 (http://rootcanalanatomy.blogspot.com). 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!

The Palato-Mesiobuccal Canal

The palato-mesiobuccal canal, a new anatomical variation of maxillary second molars with fused roots, was described for the first time in the literature by our group. In the following links you can find additional information about its morphology and clinical management:

My Book in Portuguese

 Great news! My book on Root Canal Anatomy has just been published in Portuguese. I’m so excited to share this with the Portuguese-speaking dental community!








My images in a Museum in Nuremberg

 In October 2022, I was contacted by Dr. des. Susanne Thürigen, a historian of science from the Germanisches Nationalmuseum in Nuremberg, Germany. She expressed interest in using micro-CT images of certain teeth that I had developed to be displayed in the museum's permanent exhibition on crafts and medicine. Now, the images of the root canal anatomy system, which was co-developed by myself, Frank Paqué, and Holm Reuver, are permanently on display in the Spotlight-exhibition Danger Zone in Nuremberg. It's truly an exciting achievement!
