The Effect of Sodium Fluoride on the Solubility of Calcium Phosphate, Tooth Enamel and Whole Teeth in Lactic Acid
@article{Rae1945TheEO, title={The Effect of Sodium Fluoride on the Solubility of Calcium Phosphate, Tooth Enamel and Whole Teeth in Lactic Acid}, author={James Jamieson Rae and Charles T. Clegg}, journal={Journal of Dental Research}, year={1945}, volume={24}, pages={235 - 237} }
When whole teeth were suspended in 1% lactic acid solutions, buffered with potassium hydrogen phthalate and adjusted to a pH of about 3.6, marked decalcification occurred in 24 hours at 37°. No decalcification was apparent, however, when sodium fluoride was added under the same conditions in concentrations varying from 0.2 to 0.5%. Tooth enamel was prepared according to the method of Manly and Hodge (2) and this material was used in an attempt to overcome individual variations in teeth. On…

The Effect of Various Inorganic Salts on the Solubility of Calcium Phosphate, Tooth Enamel, and Whole Teeth in Lactic Acid
- Materials ScienceJournal of dental research

In the case of lead nitrate and silver fluoride, increases instead of decreases in the weight of residue were obtained, no doubt as a result of precipitation of lead phosphate and silver phosphate, both of which have greater molecular weights than the calcium phosphate being dissolved.

It appears that the action of oxalates on tooth enamel parallels that of fluorides, as reported in the literature on the transfer of fluorine to teeth.
Critical Evaluation of the Composition and Use of Topical Fluorides, with Emphasis on the Role of Calcium Fluoride in Caries Inhibition

A reduction in pH of the agents is probably the most practical approach to increase the deposition of calcium fluoride during topical application, and clinical data support this contention.
A Note on the Mechanism of Fluoride Fixation

The present experiment was designed to determine whether, at or near neutrality where dissolution processes are not important, fluoride fixation by powdered bone simultaneously released phosphate into the solution.
Studies on the Physicochemical Phenomena Related to Dental Caries

Evaluation of the use of fluorine as a caries control measure; the effect of topically applied fluorides.
- MedicineJournal of the American Dental Association

The purpose of this article is to review the evidence relating to the use of topical fluorides and to call attention to those factors that are known as well as those which await further research and clinical demon stration.
An Evaluation of the Effectiveness as a Caries Control Measure of the Topical Application of Solutions of Fluorides
- MedicineJournal of dental research
