“…In the case of the latter, the existence of polymeric silicate anions may influence the speciation, at least initially. Because of the forcing and hazardous conditions under which such complexes form and can be studied, it is likely that a mixture of Raman scattering spectroscopy, attenuated total reflectance or mirrored internal reflectance Fourier transform infrared (ATR-FTIR or MIR-FTIR) spectroscopy, and 19 F NMR (and 29 Si NMR 136 ) spectroscopy will be required to study the kinetics and equilibria (using specialized polymer or wax vessels). Like NMR spectroscopy, radioisotope studies may also be used to probe the rate of the fluoride exchange reaction to rule out or verify mechanistic steps.…”

B. Background: Perceptions and SimplificationsA number of misconceptions and oversimplifications frequently appear in the literature, and the discussion below is intended to address them. Some of the issues are the result of recent studies, laws, or regulations, but some basic issues resurface from time to time. In 1957, a paper called "The state of fluoride in drinking water" was published, addressing many of these cyclical issues. 3 Since that time, more experimental work has been done and the knowledge base is larger, but the message is apparently being lost as many of the key outcomes have not changed. Key points may be grouped into the following categories: drinking water regulation, standards for drinking water additives, fluoridation advocacy/ requirement, available fluoridation additives, testing,
