Schematic presentation of the level of repair cementum. Craters showing a no repair, b partial repair with only a part of the surface of the resorption cavity covered with reparative cementum (arrow) and the remaining surface exposed (arrowhead), c functional repair with the total surface of the resorption cavity covered with reparative cementum (arrow) without re-establishment of the original root contour, and d anatomic repair with the total surface of the resorption cavity covered with reparative cementum (arrow) to such an extent that the original root contour is re-established
