Effect of Surface Zone Deproteinisation on the Access of Mineral Ions into Subsurface Carious Lesions of Human Enamel

Claire S. Robinson, A.S. Hallsworth, Richard F. Shore, J. Kirkham

It has been proposed that the so-called intact surface zone of carious lesions of enamel could restrict the ingress of mineral ions and hinder remineralisation. The present study was intended to determine the role of organic (proteinaceous) material in restricting the movement …

Mineral and Magnesium Distribution within the Approximal Carious Lesion of Dental Enamel

A.S. Hallsworth, Claire S. Robinson, J.A. Weatherell

The chemical changes taking place in enamel during carious attack have been studied by analysing the histologically defined zones of the small approximal lesion. Sam- pies of altered enamel were dissected from each zone and compared with sound enamel from adjacent control …

Loss of Carbonate during the First Stages of Enamel Caries

A.S. Hallsworth, J.A. Weatherell, Claire S. Robinson

The changes in carbonate concentration of enamel associated with the first visible stages of carious attack have been investigated. Samples of translucent-zone enamel and adjacent samples of sound enamel have been dissected from small carious lesions and their carbonate content determined. The …

Changes in the Fluoride Concentration of the Labial Enamel Surface with Age

J.A. Weatherell, Claire S. Robinson, A.S. Hallsworth

Using a recently developed micro-procedure, small samples of enamel, dissolved from the labial or buccal surfaces of permanent anterior teeth, were analysed to establish the pattern of fluoride distribution in the enamel surface. Considerable differences in fluoride-concentration were found from place to …

Measurement of Topical Fluoride Acquired by Sound Human Enamel

J.A. Weatherell, G P Naylor, A.S. Hallsworth

The paper discusses a particular aspect of the measurement of fluoride incorporation into sound enamel. Difficulties created by the high and variable fluoride concentration in the natural tooth surface are considered, and ways of overcoming this when attempting to measure the uptake …

Distribution of Magnesium in Mature Human Enamel

Claire S. Robinson, J.A. Weatherell, A.S. Hallsworth

The distribution of magnesium has been determined in the enamel of permanent human teeth. The concentrations increased from the surface towards the interior. The gradients were not smooth, pockets of relatively high magnesium concentration frequently occurred around the dentinal cornua and in …
