Mechanisms of Enamel Dissolution in Acid Buffers.
A quantitative understanding of the mechanism of human dental enamel dissolution in buffers is important because it should lead to a clear description of the causative factors in caries formation, and it can be profitably employed in the design of meaningful screening methods for potential anti-decay agents. Gray' has reported studies on enamel dissolution, concluding that the rates of dissolut...

Dissolution rate of apatite powders in acidic fluoride solutions and the relationship to hydroxyapatite disk and bovine enamel behavior
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 کاملCombinatorial localized dissolution analysis: Application to acid-induced dissolution of dental enamel and the effect of surface treatments.
A combination of scanning electrochemical cell microscopy (SECCM) and atomic force microscopy (AFM) is used to quantitatively study the acid-induced dissolution of dental enamel. A micron-scale liquid meniscus formed at the end of a dual barrelled pipette, which constitutes the SECCM probe, is brought into contact with the enamel surface for a defined period. Dissolution occurs at the interface...
متن کاملHigh-speed atomic force microscopy of dental enamel dissolution in citric acid.
High-speed atomic force microscopy (HS AFM) in 'contact' mode was used to image at video rate the surfaces of both calcium hydroxyapatite samples, often used as artificial dental enamel in such experiments, and polished actual bovine dental enamel in both neutral and acidic aqueous environments. The image in each frame of the video of the sample was a few micrometers square, and the high-speed ...
