What is it about?
it is an exploration of dentin and cementum of extracted teeth in patients with hypoplastic amelogenesis imperfecta. The mineralization and structure of these tissues were particularly studied by micro-radiography, scanning electron microscopy, Raman spectroscopy, pQCT, X-ray diffraction and polarized light. Areas of dysplastic dentin were noticed particularly in the inter-radicular zones and the cellular cementum was particularly abundant in areas where the dentin was scarce. Dentin was 0.6% less mineralized when compared to control teeth (p<0.001) and mainly constituted of carbonate hydroxyapatite.

Why is it important?
Enamel hypoplasia is often emphasized in this type of amelogenetic imperfecta. However, this work which is concerned with the other mineralized tissues of the tooth shows that the teeth also have an altered structure and mineralization of these tissues. Such data may be useful for planning conservative or restorative care in these patients.
Perspectives
After the structural and mineral characterization of these tissues, the prospect would be to explore whether these tissues could be affected differently under physiopathological (caries) or therapeutic conditions (acidic etching / adhesive bonding). I hope this article will help to improve the diagnosis and care of these patients.
