Copper ions inhibit the demineralisation of human enamel

Archives of Oral Biology, 2003
Cu2+ is cariostatic in rats reportedly due to it bacteriocidal properties. Here, we report the use of a simple abiotic model system to investigate whether Cu2+ has any inhibitory effect on the acid dissolution of human enamel. Crowns were exposed to a sequence of seven 10 mmol/l acetic acid challenges.

Development of an improved bone washing and demineralisation process to produce large demineralised human cancellous bone sponges

Cell and Tissue Banking, 2015
Shaped demineralised bone matrices (DBM) made from cancellous bone have important uses in orthopaedic and dental procedures, where the properties of the material allow its insertion into confined defects, therefore acting as a void filler and scaffold onto which new bone can form. The sponges are often small in size,

Guided tissue remineralisation of partially demineralised human dentine

Biomaterials, 2008
Biomineralisation is a well-regulated process mediated by extracellular matrix proteins. Biomimetic remineralisation strategies should reproduce the dimension and structural hierarchy of apatite deposits within a demineralised collagen matrix. Interfibrillar and intrafibrillar remineralisation of phosphoric acid-etched human dentine was demonstrated in

Evaluation of pH and erosion time on demineralisation

Clinical Oral Investigations, 2001
In the current study the effect of various pH values of citric acid and erosion time on erosion depth and subsurface demineralisation of human enamel was studied. In a laboratory investigation, six groups of 10 samples were eroded in 0.3% citric acid for 2 h at pH 2.54, for 2 h or 4 h at pH 3.2 and for 2 h, 4 h or 8 h at pH 4.5.

Demineralised bone matrix in veterinary orthopaedics: A review

Veterinary and Comparative Orthopaedics and Traumatology, 2010
SummaryDemineralised bone matrix (DBM) is commonly used in human orthopaedics as an allograft prepared from cortical bone. As such, there is a background of literature on the basic science, experimental animal studies and clinical human use of DBM. Because canine DBM is now increasingly available and used in veterinary orthopaedics, this review aims to

Water demineralisation by NF/MD integrated processes

Desalination, 2005
The production of demineralised water from drinking water by nanofiltration/membrane distillation system (NF/MD) has been investigated. The precipitation of CaCO3 on the membrane surface and a rapid flux decline was observed when tap water was used directly as a feed.

Demineralisation bei Krankheiten

1931
Sowohl Krankheiten wie bestimmte Ernahrungsformen konnen den S. 12 gekennzeichneten Normalmineralbestand erniedrigen. Praktisch genommen kommt wohl nur partielle, d. h. einzelne Mineralstoffe und einzelne Gewebe betreffende Demineralisation in Frage. Es war in alterer Zeit viel davon die Rede; aber mehr auf Grundlage von Abstraktionen als von Tatsachen.

Demineralisation of the dorsum sellae associated with alcoholism

The British Journal of Radiology, 1968
Abstract A group of alcoholics have been observed with changes in the sella turcica indistinguishable from those seen with increased intracranial pressure. There was no evidence of increased intracranial pressure in these men; all had normal blood pressures. In one patient laminography failed to reveal the dorsum.

A technique for the tensile testing of demineralised bone

Journal of Biomechanics, 1993
The purpose of this study was to devise a method for the tensile testing of the organic component of demineralised bone. It was hoped that the method could be applied to determine whether an observed reduction in the strength of bone in copper-deficient rats could be attributed to a reduction in the cross-linking of collagen. Tensile testing of a fully
