Abstract: 

Mineral content and distribution of fluorosed and unfluorosed (control)
dental enamel of roe deer and red deer cheek teeth were analyzed using
digital back-scattered electron (BSE) imaging of PMMA-embedded
specimens. Compared to the controls, the fluorosed enamel exhibited
various aberrations resulting from a fluoride-induced disturbance of the
processes involved in enamel formation. Thus, the presence of surface
hypopla-sias and an enhancement of the incremental pattern in the
fluorosed enamel are evidence of a fluoride impact on the secretory
ameloblasts, whereas a (subsurface) hypomineralization of different
depth and extent is indicative of a fluoride effect on the maturation
stage of amelogenesis. The marked variation in the severity of enamel
hypomineralization seen along the coronocervical axis of a specimen
pointed to a fluoride impact of varying intensity during this period of
tooth development. Our observations further indicated that, in some
locations, ameloblasts severely affected by fluoride during enamel
matrix formation were able to recover from this insult and to function
quite normally during the maturation stage of amelogenesis. A major
advantage of the BSE imaging technique used in the present study over
other methods is that it allows for a combination of micromorphological
information with quantitative data on the mineralization of the analyzed
tissue, which proved to be very useful for the characterization of
fluoride-induced changes in dental enamel.
