Synchronized crystal dissolution behavior for tooth enamel and synthetic (NBS) hydroxyapatite.
نویسندگان
چکیده
The synchronized cyrstal dissolution hypothesis previously proposed to explain the unusual dissolution behavior of human dental enamel and hydroxyapatite in partially saturated acidic media has been critically examined with dissolution-dialysis transport experiments. The findings are in accord with the hypothesis. A model based upon a variable effective solubility for the hydroxyapatite crystal is proposed.

Unusual dissolution behavior of tooth enamel and synthetic HAP crystals under high partial saturation conditions.
The dissolution behavior of enamel and synthetic hydroxyapatite in acidic media possessing a high degree of partial saturation was found to be neither simple surface dissolution nor linear with time. Instead, a repetitive, stepwise dissolution pattern was observed. To explain this phenomenon, a model based upon a hypothesis that the crystals dissolve in a synchronized fashion was proposed.
متن کاملQuantitation of enamel demineralization mechanisms. 3. A critical examination of the hydroxyapatite model.
A physical model which assumes that hydroxyapatite is the thermodynamic governing phase for the acid dissolution-rate behavior of enamel has been critically examined theoretically and experimentally. Both enamel powder and synthetic hydroxyapatite initial dissolution-rate experiments were conducted under various conditions of acid-butler type and concentration, pH, and common ion concentrations.
متن کاملThe mechanism of action of solution fluoride upon the demineralization rate of human enamel.
Equations have been derived and computations carried out for the demineralization rates of tooth enamel employing the “Fluorapatite” model. The model assumes that when hydroxyapatite is exposed to a low fluoride concentration, a layer of fluorapatite is formed around the apatite crystal and this fluorapatite is assumed to be the thermodynamic governing phase during dissolution. The demineralixa...
متن کاملCrystal chemistry and dissolution of calcium phosphate in dental enamel
The mineral component (at least 95 wt. %) of dental enamel is hydroxyapatite (hydroxylapatite) with multiple substitutions. The biogenic origin of enamel is reflected in the unusual ribbon-like morphology of the crystals, which are extremely elongated in the c-axis direction, and their organized arrangement within the tissue. The study of enamel dissolution has been driven by the very high prev...
متن کاملSynthesis of Boron Nanocomposites Doped on the Hydroxyapatite-Chitosan Surface and Its Effect on the Microhardness of Demineralized Tooth Enamel
Background and Objective: Noninvasive treatments are preferred for tooth enamel remineralization, and metal nanocomposites could be used for this purpose. The present study investigated the effect of boron nanocomposites doped on the hydroxyapatite-chitosan surface on the microhardness of demineralized tooth enamel. Materials and Methods: In this laboratory study, boron nanocomposites doped on...
