Three-dimensional analysis of the physiological foramen geometry of maxillary and mandibular molars by means of micro-CT

German and Swiss scientists have used computerized scanning techniques to map the root tips of molars to better inform dental practitioners. This research is highly applicable to clinical practice, as proper treatment of the root tips is a determining factor of root canal surgery success. Thomas Wolf of Germany’s Johannes Gutenberg University of Mainz led a team to analyze 516 first and second human molars, scanning both upper (maxillary) and lower (mandibular) teeth to elucidate the anatomy of the root apex, the junction between the tooth and its surrounding tissue. This work allows scientists to provide recommendations on how dentists can best shape root canals during therapy. As well as a better understanding of tooth anatomy, this study presents the first fine-detail measurements of the root apex geometry of the first and second mandibular and maxillary molar.
