Unusual dissolution behavior of tooth enamel and synthetic HAP crystals under high partial saturation conditions.
نویسندگان
چکیده
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.

Orientation and deformation of mineral crystals in tooth surfaces.
Tooth enamel is the hardest material in the human body, and it is mainly composed of hydroxyapatite (HAp)-like mineral particles. As HAp has a hexagonal crystal structure, X-ray diffraction methods can be used to analyze the crystal structure of HAp in teeth. Here, the X-ray diffraction method was applied to the surface of tooth enamel to measure the orientation and strain of the HAp crystals. ...
متن کاملSynchronized crystal dissolution behavior for tooth enamel and synthetic (NBS) hydroxyapatite.
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...
متن کاملTwo-site model for human dental enamel dissolution in EDTA.
Dissolution of tooth enamel and of hydroxyapatite (HAP) in buffered solutions of ethylenediaminetetraacetic acid (EDTA) has been studied in this laboratory by the physical model approach. To quantitatively explain the experimental results, it was necessary to develop a model incorporating two different types of crystalline sites for dissolution. In a previous study using a one-site diffusion la...

The dissolution kinetics of synthetic hydroxyapatite (HAP) and carbonate-containing HAP powders have been studied in fluoride-containing acetate buffer solutions partially saturated with respect to HAP (K,, = 10-‘15 to IO-“‘). The experimental results indicate that in the ease of HAP powders the dissolution rates become veqr slow when the K,,, values of the dissolution medium are larger than 10...
متن کاملRole of crystal arrangement on the mechanical performance of enamel.
The superior mechanical properties of enamel, such as excellent penetration and crack resistance, are believed to be related to the unique microscopic structure. In this study, the effects of hydroxyapatite (HAP) crystallite orientation on the mechanical behavior of enamel have been investigated through a series of multiscale numerical simulations. A micromechanical model, which considers the H...
