The objective of this study was to investigate the efficiency saturation mixed saliva by mineral complexes and groups necessary for remineralisation tooth enamel using exogenous endogenous methods caries prevention. Using IR spectroscopy high-intensity synchrotron radiation, changes in composition human were identified when prevention are employed. Based on calculations mineral/organic carbon/phosphate ratios, depending a certain type identified. It is shown that use toothpaste (exogenous...
Investigations of intact dental enamel as well carious-affected human were performed using infrared spectromicroscopy and X-ray diffraction applying synchrotron radiation. Caries was shown to be characterized by an increase in the number deformation valence vibrations for N-C-O, N-H C=O bonds, a decrease crystallinity index, absence preferable orientation hydroxyapatite crystals within affected enamel. This indicates presence destructive processes organic matrix hard tooth tissues.
In this report, we demonstrated the formation of a biomimetic mineralizing layer obtained on surface dental enamel (biotemplate) using bioinspired nanocrystalline carbonate-substituted calcium hydroxyapatite (ncHAp), whose physical and chemical properties are closest to natural apatite matrix, together with complex polyfunctional organic polar amino acids. Using set structural, spectroscopy, advanced microscopy techniques, confirmed nanosized ncHAp-based mineralized layer, as well studying...
In our paper, we discuss the results of a comprehensive structural-spectroscopic and microscopic analysis non-stoichiometric nanocrystalline hydroxyapatite (CHAp) with low carbonate anion content biomimetic hybrid nanomaterials produced on its basis. It was shown that nanocrystals synthesized by chemical precipitation biogenic calcium source mimic properties apatite also have morphological organization “core–shell” type. The “core” CHAp nanocrystal is characterized an overabundance Ca/P~1.9....
Abstract Nanoporous silicon layers were obtained on different types of single crystalline substrates by standard electrochemical etching in HF solution. Investigations electron structure, surface phase composition and photoluminescence evolution nanoporous during natural ageing for the time period up to one year performed with use ultrasoft X‐ray emission spectroscopy (USXES), absorption near‐edge structure (XANES) photoluminescence. USXES XANES spectra represent local partial density states...
(1) Objectives: This study is the first one to investigate molecular composition of dental biofilm during exogenous and endogenous prophylaxis stages (use dentifrice/drug) individuals with different cariogenic conditions using spectroscopy methods. (2) Materials Methods: The involved 100 participants (50 males 50 females), aged 18-25 years caries conditions. Biofilm samples were collected from teeth surface all participants. biofilms was investigated synchrotron infrared microspectroscopy....
