(4) Enamel was exclusively present opposite well developed dentine.
(5) Data is available to support the early influences of enamel organ epithelium upon a responding mesenchyme in the determination of dental morphogenetic fields (Dryburg, 1967; Miller, 1969).
(6) To determine the influence of cetylpyridinium chloride (CPC) adsorption on the wettability and elemental surface composition of human enamel, with and without adsorbed salivary constituents, surface-free energies and elemental compositions were determined.
(7) The 12-fluted bur caused no clinically identifiable marks on the enamel surface.
(8) Unaltered surface enamel of extracted human teeth was subjected to tests of resistance to dissolution in 10 mM acetic acid at pH 4.0 and 10 mM EDTA at pH 7.4 in a miniature continuous flow system.
(9) Secondary structural features of bovine amelogenin, a hydrophobic protein of developing enamel implicated in ename mineralization, are derived using 2D NMR spectroscopy in solution and molecular mechanics-dynamics studies.
(10) Several functional properties of MG1, MG2, and PRG have been examined, including their presence in two-hour in vivo enamel pellicle, binding to synthetic hydroxyapatite, lubricating properties, and interactions with oral streptococci.
(11) A thorough dental prophylaxis before acid-etching of enamel is often recommended.
(12) Changes of mineral content in the approximal enamel of the teeth were determined in situ with quantitative bite-wing radiography.
(13) On the fourth day of culture, the pre-ameloblasts achieved terminal differentiation into secretory ameloblasts, and enamel and dentin had already been deposited.
(14) This resulted in greater uniformity of abrasion over the enamel surface within the biopsy window area and better operator handling characteristics.
(15) The 33,000 molecular weight protease was also active against enamel proteins.
(16) Significantly more remineralization was observed in enamel samples treated with the toothpaste containing 2,500 ppm F compared to that containing 1500 ppm F. This result is consistent with the outcome of a recent caries clinical trial testing the same toothpastes and finding enhanced anticaries efficacy from the higher fluoride level.
(17) This demineralization was similar to enamel acid etched with 50% phosphoric acid for 2 mn.
(18) The data show that the structure of inner and outer enamel layers differ between these two carnivore species and that the enamel structure of the cat was most similar to that described in humans.
(19) Maturing enamel overlaid by either ruffle-ended or smooth-ended maturation ameloblasts showed similar Ca and P concentrations.
(20) Although the crystallite widths were similar in both AI and normal enamel, the AI teeth showed areas where the crystallite order and continuity appeared disrupted.
Ganoine
Definition:
(n.) A peculiar bony tissue beneath the enamel of a ganoid scale.
Example Sentences:
(1) The lack of dentin in lepidotrichia emphasizes the tendency during evolution toward the reduction of some dermoskeletal components and exemplifies ganoine deposition directly on top of the bone as in holostei scales.
(2) Two novel pyrrole alkaloids--ganoine and ganodine and a novel purine alkaloid ganoderpurine have been isolated from the mycelium of Ganoderma capense (Lloyd)Teng (Polyporaceae) obtained by submerged fermentation.
(3) The outer region is the superficial part of the mature scale (called here osteodentin), which is covered by the ganoine deposited by the epidermal cells.
(4) In order to understand the process of ganoine formation on the ganoid scales, scale regeneration has been studied to overcome the lack of a growth series of scale ontogeny.
(5) This layer is interpreted as "anti-slip pad" or elastic glue anchoring the epidermis on the hypermineralized ganoine.
(6) An irregular patch of ganoine susceptible to erosion by vascular canals lies on top of the cellular bone of the upper surface of the segment.
(7) This layer is progressively mineralized; and finally an organic intermediate layer differentiates between the ganoine, which is a hyper-mineralized tissue, and the overlying epidermis.
(8) On the basis of spectroscopic data their structures were elucidated, ganoine is N-isopentyl-5-hydroxymethyl-pyrryl alldehyde.
(9) Numerous alterations of the epidermal-dermal boundary occur until its disappearance and a thick layer of pre-ganoine is formed.
(10) Consequently, our results allow us to propose that ganoine can be identified as true enamel, although additional data are necessary to analyze the proteinaceous component or its organic matrix.

(12) This ultrastructural study demonstrates rather unequivocally the involvement of the inner epidermal layer (IEL) in the appearance and growth of the ganoine.
