The cover picture illustrates the birth of root cementum. Opposite the dentin-pulp complex and apical to enamel and ameloblasts, a number of seemingly inconspicuous cells have assembled in front of the root surface, ready to deposit a mineralized tissue layer onto the already existing root dentin. This mineralized tissue layer is called cementum. It is one of four mineralized tissue types in the human body. The origins of this unusual tissue are still not completely understood. See the review paper by Diekwisch in the present issue.
