Light microscope view of different levels of repair. Magnification of ×10. a Partial repair of resorption crater seen in a tooth from group A. Only a part of the surface of the resorption crater is covered with reparative cementum, and the remaining surface is exposed (black arrow). b Functional repair of resorption crater seen in a tooth from group A. The entire surface of the resorption crater is covered with reparative cementum without re-establishment of the original root contour. c Anatomic repair of resorption crater seen in a tooth from group B. The entire surface of the resorption crater is covered with reparative cementum to such an extent that the original root contour is re-established. White arrow indicates the reversal line in each image
