OBJECTIVE
To evaluate the effect of 10% cerium chloride intervention on pre-demineralised human enamel subjected to cycles of de- and remineralisation.
METHODS
This was an in vitro, comparative type study of 60 human enamel samples that were randomly divided into control and test groups. The samples
OBJECTIVE:The present study was to investigate the effects of combined application of lanthanum,cerium and fluoride-contained gel on root surface caries.METHODS:2000ppm lanthanum.cerium and fluoride-contained gels were used by various procedures to treat 164 teeth with root surface
In order to evaluate the anticaries effects of several trace elements by combined and respective treating procedure, studies on inhibiting demineralization and improving remineralization were carried out with lanthanum, cerium and fluoride in a pH-cycling condition. The analysis of polarized
Ultraviolet (UV) miniature cerium fluoride lasers have been demonstrated using a low cost, frequency-quadrupled microchip Nd:YAG pump laser. The use of miniature laser cavities was shown to significantly improve the laser performance in the low pump power region. We have achieved slope efficiencies
Cerium-based triple-strand helicates Ce-CL(1) and Ce-CL(2) were achieved via self-assembly from malonohydrazone derived bis-tridentate ligands H(2)CL(1) and H(2)CL(2), respectively. Structure analysis of Ce-CL(1) shows that six oxygen atoms of the β-diketone groups on the ligands form a lantern-like
Electrode materials are the most significant components of lithium-ion batteries (LIBs) and play an important role in endowing them with high electrochemical performance. The exploration of new electrode materials and their comparative study with contemporary resources will help the design of
We report the structure and stability of ceria units deposited on the surface of γ-Al2O3 or incorporated in its cavities, as determined by periodic density functional calculations. Ceria species are modeled as CeO2 or Ce2O4 moieties or as a small nanoparticle, Ce13O26, on the (100) and (001)
OBJECTIVE
Peritonitis is a life-threatening disease that is associated with high mortality. The purpose of this study was to determine if cerium oxide nanoparticles can be used to diminish intra-abdominal infection-induced mortality and systemic inflammatory response syndrome in the laboratory
Incipient dental caries--according to up-to-date concepts in dental research--means a demineralization without cavity formation. At this stage the carious process is reversible, and remineralization can be achieved in the presence of locally applied fluorides. In chrystalchemical experiments,
Ion-imprinting polymers (IIPs) materials draw the great recognition because of the powerful selectivity to the desired metal ions. Therefore, the ion-imprinting polymer (Ce-IIP) was prepared by using cerium metal with amidoxime ligand as the complexing agent, in addition ethylene glycol
OBJECTIVE
Determination of the potential of cerium chloride to reduce artificial carious mineral loss and lesion depth progression.
METHODS
A total of 160 enamel samples were prepared from 40 bovine lower central incisors. Crowns were sectioned into four pieces, embedded in acrylic resin, ground
A method was developed for the demonstration of 5'-nucleotidase in murine peritoneal resident macrophages. The cells are incubated cytochemically without agitation and cerium chloride is used as a trapping agent. Under these conditions, the great majority of the macrophages in the unstimulated
OBJECTIVE:The present study was to investigate the systemic and local acute toxicity of the lanthanum(La) and cerium(Ce) to the mice. METHODS: 0.2% and 1% La and Ce solutions were applied to buccal mucoa of mice.The systemic conditions and local histopathological changes were observed. RESULTS: The
The severe inflammation observed during sepsis is thought to cause diaphragm dysfunction, which is associated with poor patient prognosis. Cerium oxide (CeO2) nanoparticles have been posited to exhibit anti-inflammatory and antioxidative activities suggesting that these particles may be of potential
