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

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.

Effect of Fluorides and other Compounds on the Solubility of Enamel, Dentin, and Tricalcium Phosphate in Dilute Acids

A study of a new and more precise method for determining changes in the solubility of enamel, dentin, and tricalcium phosphate in an acetate buffer.

The present paper describes the general effect of 5 fluorides on the accessibility of the inorganic and organic components of human dentin exposed to 6 organic and 2 inorganic acids.

Transfer to teeth of topically applied, carbon-tagged sodium oxalate.

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

A study is designed to test the effect of Sucrose on tooth enamel solubility in acid solutions to determine further influences of a physicochemical nature exerted by sucrose on the process of caries development.

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

It is concluded that the use of topical fluorides as a preventive measure in dental caries control is approximately 40 per cent effective in reducing the incidence of the disease.



Density and Refractive Index Studies of Dental Hard Tissues

A rapid, quantitative method for the separation of the enamel, dentin, and cementum of a single tooth to obtain samples of known purity will permit the following investigations: 1) Normal values and
