The effect of temperature on the stability of sodium hypochlorite in a continuous chelation mixture containing the chelator clodronate [PDF]
Australian Endodontic Journal, 2020 AbstractThis study evaluated the stability of continuous chelation mixtures of clodronate admixed with sodium hypochlorite at room temperature (23°C), at root canal temperature (34–35°C) and in refrigerated storage (2–4°C). In continuous chelation, one solution containing a chelator and sodium hypochlorite simultaneously disinfects and removes organic ...

The effects of sequential and continuous chelation on dentin
Dental Materials, 2020 Proteolytic and demineralizing agents have a profound influence on the dentin ultrastructure, which plays a key role in the mechanical integrity of the tooth and integrity of dentin-biomaterial interfaces. In-depth characterization of dentin treated with a novel root canal irrigation protocol comprising sodium hypochlorite (NaOCl) and etidronate (HEDP)

Odontology / the Society of the Nippon Dental University, 2022 This study aimed to evaluate the influence of continuous chelation on apical transportation and centrality in shaped curved canals prepared with a martensitic file system and evaluated by micro-CT. Twenty-four lower molar canals with a curvature of 25º-40º were scanned pre-operatively with micro-CT and divided into 2 groups according to two different ...

Journal of Endodontics, 2019 Tetrasodium etidronate (Na4 etidronate) and tetrasodium EDTA (Na4 EDTA) are chelators that can combine with sodium hypochlorite (NaOCl) as a 1-mix endodontic irrigant in a process called continuous chelation. The therapeutic window of these mixtures is determined by the chemical reaction between NaOCl and the chelator.

Continuous Soft Chelation in Endodontics
RGUHS Journal of Dental Sciences, 2022Chemome chanical debridement is accompanied by three-dimensional obturation of the root canal system in endodontic therapy. Endodontic irrigation requires sodium hypochlorite (NaOCl) as it dissolves organic matter and disinfects the root canal. The smear layer is removed by chelating agents.

To further examine the potential clinical usefulness of the hexadentate phenolic aminocarboxylate iron chelatorN,N′-bis(2-hydroxybenzyl)ethylenediamine-N,N′-diacetic acid (HBED) for the chronic treatment of transfusional iron overload, we performed a subchronic toxicity study of the HBED monosodium salt in rodents and have evaluated the iron excretion ...

Continuous chirality analysis of hexacoordinated tris-chelated metal complexes
Crystal Engineering, 2001We use the notion that symmetry can be evaluated on a continuous scale for the quantitative chirality analysis of tris-chelated metal complexes. After reviewing the Continuous Symmetry Measures methodology and its resulting Continuous Chirality Measure, we analyze the chirality of these complexes in terms of the specific contributions from the ...

Continuous chirality measures of tetracoordinate bis(chelate) metal complexes
Dalton Transactions, 2003The interconversion pathway between the tetrahedron and the square that is represented by the structures of a large variety of tetracoordinate complexes is the achiral spread pathway in the presence of monodentate ligands but the chiral twist pathway in bis-chelated complexes.

This paper introduces a mathematic mode of moving chelation boundary (MCB) for computer simulation of a continuous EDTA-based sample sweeping in capillary electrophoresis (CE). Besides the equations of MCB used herein, the mode also includes electro-neutrality equation, constant current density, jump boundary condition of MCB, Kohlrausch' regulating ...
