Quantification of Sulfur Speciation in Apatites: Comparison of the XAS, XPS and EPMA Techniques

Geostandards and Geoanalytical Research, EarlyView.
Key Points Sulfur speciation in apatites has been determined by S K‐edge X‐ray absorption near‐edge structure (XANES) spectroscopy, S 2p X‐ray photoelectron spectroscopy (XPS) and electron probe microanalysis (EPMA). XANES provides the most sensitive and accurate quantification of sulfur speciation.

Incorporation of Calcium Polyphosphate Sub‐Microparticles in Commercial Toothpastes and Their Effects on Dental Enamel

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Dental bleaching with 35% hydrogen peroxide (HP) can cause deleterious effects on the mineral content of enamel. In this regard, remineralizing submicroparticles of calcium polyphosphate (CaPP) have been investigated for their ability to deposit calcium ions into enamel's hydroxyapatite.
