An Evaluation of Various Technics for Reducing Decalcification of Enamel

The Effect of Fluorides on the Organic and Inorganic Components of Intact Dentin

“…The decalcifying acids most often used to test the solubility of tooth tissues in vitro are acetiC2' 4, 8, 10 and lactic acid.5 9,12 Lactobacillus cultures have also been used to determine the solubility of such tissues. 13 More recently, the effect of 147 compounds, comprised of 57 elements, was tested on the acid solubility of powdered enamel.10 From that study 27 compounds were reported to depress the solubility of the powdered enamel in vitro more than fluorides, and several fluorides were found to be more effective than sodium fluoride. Nevertheless, very few ions other than fluorine have been of practical value in preventing dental caries.…”

Alkaline and Acidulated Fluorine Solutions for Reducing Decalcification of Enamel

“…3ALMER, Overstreet, and Sacks1' 2, 3 have shown that when the enamel surl faces of both nondecalcified teeth and enamel-dentin fragments were treated with an acidulated fluoride solution and immersed in broth seeded with Lactobacillus acidophilus for thirty days, decalcification of enamel was reduced from 31.69 to 39.37 per cent. In a previous report3 it has been shown that when 2 per cent sodium fluoride solution was applied to both previously decalcified teeth and enamel-dentin fragments, it was as effective for reducing further decalcification of enamel as when applied either to nondecalcified teeth or nondecalcified enamel-dentin fragments.…”
