The surface of wedge shaped defects of 51 extracted teeth was examined with the scanning electron microscope. To study morphology of surfaces of 12 defects in vivo a replication technique was carried out. It was shown that there is a relation between the morphological features and the clinical symptoms. In the progression of the defects there are active and passive phases, what will be reflected on the one side in the clinical symptoms and on the other side in the morphological features.
