you got me all interested in this subject,
not trying to "fight", but continue a discussion:
first of all,
osteosarcoma
i have yet to see something that had fluoride as etiology for
osteosarcoma
uptodate:
the majority of osteosarcomas are sporadic (= no exact cause set),
while inherited predisposition accounts for a minority of cases.
Risk factors:
Prior irradiation or chemotherapy
Paget's disease and other benign bone lesions
Inherited conditions - Genetic conditions : ...retinoblastoma, Li-
Fraumeni syndrome, Rothmund-Thomson syndrome, and the related Bloom
and Werner syndromes
blah: bone tumors arise from an aberration of the normal process of
bone growth and remodeling at a time when rapidly proliferating cells
are particularly susceptible to oncogenic agents, mitotic errors, or
other events leading to neoplastic transformation [18]. However,
studies examining the relationship between factors related to growth
and development and the risk of bone sarcomas have revealed no
consistent pattern

fluoride = loss of teeth, and jaw bone ???
never heard of that
excess fluoride will do some damage in child's teeth impairing enamel
formation or something,
but
loss of jaw bone!!!??? where do you find this????
3:
do you have any published studies in big journals, not pubmed obscure
research articles?
http://search.nejm.org/search?p=Q&ts=subs&w=fluoride
62 articles
only 2 have fluoride in the title and they concern acute poisoning in
children.
http://content.nejm.org/cgi/content/full/338/10/681 (1998)
Moreover, primary mineralization defects, whether genetic (as in
hypophosphatasia) or acquired (e.g., as a result of excess fluoride,
aluminum, or bisphosphonate), are rare causes of rickets or
osteomalacia.
nejm Volume 333:1495-1496 November 30, 1995 Number 22
Internationally, the agents used most widely for the treatment of
postmenopausal osteoporosis are calcium, estrogen, calcitonin,
fluoride, calcitriol, and an early bisphosphonate, etidronate. In
general, these agents can be divided into two categories according to
whether they stimulate bone formation or inhibit bone resorption.
Fluoride, the only one of these agents that stimulates bone formation,
can increase bone density substantially. The effect of fluoride on the
risk of fractures has been disappointing, although reanalysis of the
data from one large trial showed a protective effect in women who had
moderate increases in bone density,3 and new, slow-release
formulations offer promise.
nejm Preventing Glucocorticoid-Induced Osteoporosis 337:420, August 7,
1997
increases bone density. There is also some evidence of the
effectiveness of calcitonin and fluoride in this context.

Fluoride - Fluoride is added to water to prevent dental caries; this
agent may contribute to bone disease in hemodialysis patients,
although the evidence for such a role is weak .

urging primary care physicians to prescribe oral fluoride supplements
to infants older than 6 months and preschool children if their
community water supply is deficient in fluoride
ask local health departments about water fluoride levels to avoid
oversupplementation. Excess levels of fluoride can lead to fluorosis
and cause mild discoloration of teeth.

ADA Positions & Statements
Interim Guidance on Fluoride Intake for Infants and Young Children
Recent studies cited in the report of the National Research Council
(NRC), "Fluoride in Drinking Water: A Scientific Review of EPA's
Standards," have raised the possibility that infants could receive a
greater than optimal amount of fluoride through liquid concentrate or
powdered baby formula that has been mixed with water containing
fluoride during a time that their developing teeth may be susceptible
to enamel fluorosis.
The appropriate amount of fluoride is essential to prevent tooth
decay. But fluoride intake above optimal amounts can create a risk for
enamel fluorosis in teeth during their development before eruption
through the gums.
Enamel fluorosis is not a disease but rather affects the way that
teeth look. Most cases of fluorosis result in faint white lines or
streaks on tooth enamel that are not readily apparent to the affected
individual or the casual observer.
