title: [Pathomorphology of wedge-shaped defects].
abstract: Our function-oriented SEM studies of various stages of wedge-shaped defects on permanent teeth have shown that wedge-shaped defects probably result from parafunctional force application. These dental hard tissue defects are characterized by marginal surface fractures, arch-shaped enamel tears and axial enamel rod fractures with formation of sagittal gaps. The enamel fractures indicate a dynamic process and do not appear to be the result of improper toothbrushing technique.
