[Ultrastructural odontological study of a case of Papillon-Lefèvre disease].
An ultrastructural study of the teeth and alveolar bone was carried out in a case of Papillon-Lefevre disease, using sweep electron microscopy. There were structural abnormalities of the enamel, numerous zones of cement resorption, the absence of mineralisation of the parodontal fibres inserted in the cement. Osteogenesis was disturbed and the lamina dura showed a granular pattern without any defined orientation.
