Abstract: 

The interdental and interspecific variation in the prevalence and
severity of macroscopic fluorotic alterations of the permanent
mandibular cheek teeth (P_2–4, M_1–3) was studied in
331 roe deer and 62 red deer exhibiting severe dental fluorosis. The
material originated from the fluoride‐polluted region of the Ore
mountains and their southern foreland (Czech–German border region).
Scoring of dental fluorosis was based on an ordinal measurement scale
with six scores (score 0: unfluorosed, scores 1–5: increasing severity
of fluorotic alterations). The observed variation in dental fluorosis
both within the cheek tooth row of a species and between certain
homologous teeth of roe and red deer could be related to the development
of the dentition in the two species, especially the timing of tooth
crown formation in relation to weaning and the subsequent period, where
the animals feed upon (fluoride‐contaminated) plant material. The lower
prevalence (roe deer: 3%, red deer: 42%) and severity (fluorosis scores ð
2) of dental fluorosis in the M₁ compared to the other
permanent cheek teeth were attributed to the fact that the crown
formation of this tooth takes place largely (roe deer) or to a
considerable extent (red deer) prenatally and during the period of milk
feeding. It is assumed that during these ontogenetic stages several
mechanisms (partial placental diffusion barrier to fluoride, low
fluoride content of milk, rapid clearance of fluoride from the blood
resulting from a high skeletal growth rate) to some extent protect the
developing teeth from increased fluoride exposure. Therefore, in both
species apparently only the (late) maturation stage of M₁
amelogenesis can be affected by fluoride in a way to induce visible
enamel changes. The higher prevalence and severity of fluorotic lesions
in the M₂ of red than roe deer was related to the fact that in the former species crown formation of this tooth, like in the P_2–4 and M₃ of both species, takes place completely post‐weaning.
