Abstract: 

The purpose of this study was to examine, using backscattered electron
imaging, the changes occurring in the structure of the dentine including
giant tubules in the teeth of deer chronically exposed to fluoride. The
primary and secondary dentine was characterised by the presence of
interglobular dentine and regular bands of hypo- and hypermineralised
dentine. Giant tubules in the unworn teeth of animals exposed to low and
high levels of fluoride were characterised by a large lumen and
hypermineralised rim in which there were calcospherites. With the
occlusal wear of the teeth tubules beneath the immediate surface of the
exposed dentine in teeth from fluorotic animals became occluded with
mineral, but in low fluoride animals some tubules at the surface were
not occluded with mineral. It is suggested that mineral which occludes
the tubules may come from both intrinsic and extrinsic sources. The
presence of some open tubules at the immediate surface in the worn teeth
of animals exposed to low fluoride suggests an extrinsic source for
this mineral.
