Growth tracks in dental enamel
Journal of Human Evolution, 1998The present paper evaluates the enamel growth tracks as tools in the chronological mapping of dental development, with special reference to hominids. Dental enamel consists of tightly packed hydroxyapatite crystals organized by differential orientation into a pattern of prisms and interprisms. The crystal organization is probably under the influence of

Enamel formation Enamel is the outermost covering of vertebrate teeth and the hardest tissue in the vertebrate body. During tooth development, ectoderm-derived ameloblast cells create enamel by synthesizing a complex protein mixture into the extracellular space where the proteins self-assemble to form a matrix that patterns the woven hydroxyapatite ...

Trapped Water of Dental Enamel
Nature, 1965RECENT investigations with polarizing microscopy have indicated that some of the water of dental enamel is not easily removed by dehydrating methods. Somewhat more severe treatment of enamel is necessary to remove the last portion of water and these more drastic conditions bring about irreversible changes in enamel1.

THE VITALITY OF THE DENTAL ENAMEL
Journal of the American Medical Association, 1909My interest in this subject has been renewed recently by being shown some very beautiful sections and photographs of enamel prepared by Dr. C. Francis Bodecker, of Berlin. The sections were decalcified by the celloidin decalcifying method which stains the tissue at the same time. The photographs were made by the ultraviolet light. These enamel sections

The Effect of Copper on Demineralization of Dental Enamel
Journal of Dental Research, 2006Previous studies have concluded that copper might inhibit enamel demineralization in vitro. Our aim was to assess the effect of copper (Cu2+), with and without amine fluoride, on human dental enamel under cariogenic challenge in situ. In a double-blind randomized four-leg crossover trial, 14 individuals wore a removable appliance containing 2 enamel ...

The crystalline component of dental enamel
1960It has been shown through earlier electron microscopy that the crystalline apatite which is the major component of mature dental enamel is overlaid upon a framework of very fine organic fibrils (1, 2). There has been difficulty, however, in observing both the inorganic and organic constituents in the same preparation.

Thermoluminescence dating of dental enamel
Nuclear Instruments and Methods, 1980Abstract Thermoluminescent response of the synthetic hydroxylapatite was studied, this material being the fundamental inorganic constituent of dental enamel. In order to make an attempt at archaeological TL dating of teeth, a chemical deproteination procedure of enamel was established, and the pre-dose effects of separated mineral grains extracted ...

The pore structure of human dental enamel
Archives of Oral Biology, 1973Abstract Water vapour sorption isotherms of intact enamel reveal permanent and reproducible hysteresis loops extending to very low relative pressures. However, a detailed pore volume analysis shows that true micropores are absent. These results and those obtained by scanning the hysteresis loops are consistent with the presence of constrictions ...

Dental Enamel Hypoplasias in Prehistoric Populations
Advances in Dental Research, 1989Recent years have witnessed an impressive increase in research on enamel hypoplasias in archaeological populations. By reviewing a series of studies of enamel hypoplasias at Dickson Mounds, Illinois, North America (950-1300 A.D.), a prehistoric site involved in the transition from gathering-hunting to agriculture, this paper provides an illustration ...

Optical Properties of Dental Enamel
Nature, 1939IT has been known for many years that dental enamel is birefringent; and its optical properties have been studied intensively by W. J. Schmidt and his pupils1. In a recent paper2, I have shown by X-ray examination that an enamel prism contains a multitude of regularly arranged crystallites of apatite, and have worked out in detail the orientation of ...
