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!

The Worldwide Studies

The Worldwide Studies

The Worldwide Studies are an ongoing project under the supervision of Dr Jorge Martins (Portugal) on the evaluation of root canal anatomy using CBCT technology. It counts with the collaboration of researchers and clinicians from several countries with the aim to unveil the anatomical variations and the most prevalent canal configurations of thousands of teeth according to gender, geographic location and ethnic group. Right now there are 4 published studies and I had the opportunity to work in some of them. In 2022, a new phase from this project has started with the aim to publish at least 3 additional papers with the collaboration of people from 49 countries! A great achievement for our specialty. You can read the already published studies by clicking on the images below:

Sometimes, anatomy makes me crazy

If the supervillain Thanos from Marvel decided that root canal should die

The anatomy and the heat-treated instrument are based on real objects (microCT-based model).
But - in clinics - would it be able to do that?
