Effects of root morphology on stress distribution at the root apex [PDF]
The European Journal of Orthodontics, 2007 It is thought that the stress concentration at the root apex caused by orthodontic force induces root resorption. The purpose of this study was to investigate stress distribution at the root in cases of deviated root shapes using finite element models (FEMs).

A new system for classifying root and root canal morphology [PDF]
International Endodontic Journal, 2016 AbstractKnowledge of root and root canal morphology is a prerequisite for effective nonsurgical and surgical endodontic treatments. The external and internal morphological features of roots are variable and complex, and several classifications have been proposed to define the various types of canal configurations that occur commonly.
