Abstract: 

The nature of deposits present in hypoplastic defects of fluorotic
enamel of wild boar teeth was studied by light microscopy and scanning
electron microscopy. The fluorotic enamel showed different developmental
abnormalities, denoting a severe disturbance of ameloblast function
during the secretory stage of amelogenesis. These abnormalities included
the occurrence of grossly accentuated incremental lines with associated
zones of aprismatic enamel and the presence of different forms of
hypoplastic defects. Two types of deposits were present on the
hypoplastic enamel: cellular cementum and posteruptively acquired,
presumably partially mineralized dental plaque. Coronal cementum is not
normally formed in pig teeth. Presence of this tissue in fluorotic teeth
of wild boars is seen as indicative of a premature disintegration of
the enamel epithelium prior to the completion of amelogenesis. This was
supposed to have resulted in a contact of mesenchymal cells of the
dental follicle with the surface of the immature enamel and, in
consequence, in a differentiation of these cells into cementoblasts. To
our knowledge, this is the first study reporting the formation of
coronal cementum as part of the spectrum of pathological changes in
fluorotic teeth in a species whose tooth crowns are normally free of
cementum.
