Available in PDF, EPUB and Kindle. Book excerpt: Samples of sound, untreated enamel and enamel subjected to a number of different treatment procedures were selected for this study, to determine the potential of the scanning electron micro-scope as applied to the study of dental tissue. Sound enamel specimens were treated with acetate buffer (pH 4.0) and with EDTA (pH 7.94) for varying periods of time. The results were compared to those obtained from sound, untreated enamel specimens. Surface and sub-surface enamel morphology and bacteria-like structures were examined, photographed at magnifications ranging from 20X to over 100,000X, and described in relation to the ultra-structural morphology of enamel. Structures resembling enamel prisms, the 'prism-less' zone of surface enamel, the surface covering of an 'enamel skin' and sequential patterns of acid demineralization occuring preferentially down prism cores are described and illustrated. Comparison with EDTA-treated specimens revealed peripheral dissolution of enamel rods, in contrast to the acid effects. Organic surface coverings suggestive of dental plaque and microbial forms resembling cocci and lactobacilli were also shown. (Author).

Download or read book Demineralization Studies of Pre fluoridated Dental Enamel Surfaces by Scanning Electron Microscopy written by Seymour Hoffman and published by . This book was released on 1969 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Samples of sound dental enamel were treated with topical applications of a 10% solution of stannous fluoride and then demineralized using acetate buffer (pH 4.0) and EDTA (pH 8.0) for varying periods of time. Nonfluoridated enamel treated for equivalent periods with the acetate buffer and with the EDTA, as well as untreated enamel, served as controls. A scanning electron microscope comparison of the surface alterations produced within the different groups revealed that: the in-virto application of stannous fluoride solutions inhibited enamel surface alterations when challenged by an acid or chelating agent. This finding adds further support to the concept that fluoride protection involves a reduction in enamel solubility. In addition, there was suggestive evidence that fluorides possibly play a role in the remineralization or repair or early etched enamel defects by the formation of a fluoride complex which may involve the less mineralized enamel matrix components.

This book was released on 1979 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: SEM studies were performed on 25 deciduous and permanent teeth from members of seven kindreds with autosomal dominant osteogenesis imperfecta (O.I.). Two families had normal teeth on clinical and radiological examination; five families had blue or brown opalescent teeth with specific radiologic findings. Enamel surfaces and prism organization were normal on all teeth. On fractured surfaces, the dentin tubules of normal teeth from patients with O.I. were evenly distributed and coursed regularly to the dentin-enamel junction. Opalescent teeth had few tubules; those tubules present were narrow, short, and tortuous. Dentin calcification fronts of normal teeth were composed of many mushroom shaped nodules, with regularly spaced openings on their surfaces. Calcification fronts of opalescent teeth were composed of irregularly spaced, small nodules, which varied greatly in size one from another; the nodules lacked tubule openings on their surfaces. The results of this study support the concept that two autosomal dominant O.I. syndromes exist, one in which all individuals with O.I. have normal teeth, and the other in which all with O.I. have blue or brown opalescent teeth.

Available in PDF, EPUB and Kindle. Book excerpt: The editors and the publisher are pleased to present another volume in this series of monographs. The topic of teeth was last reviewed within the framework of this Handbook more than fifty years ago, in 1936, by Josef Lehner and HanDs Plenk of Vienna, who wrote a comprehensive treatise on the subject in volume V 3. / The introduction of new methods (e.g., transmission and scan ning electron microscopy, histochemistry, radioautography, element analysis) and progress in dental research have made an update necessary. In present times, characterized by scientific specialization and very rapid progress, it is virtually impossible to find a single individual prepared to review a field of research as large as that of teeth. Consequently. several authors were asked to contribute to the present volume. Originally. the intention was to cover the field in one volume. When it became clear that the material had become too extensive for a single volume, and when some authors were forced by external factors to withdraw from the project, it was decided to publish two volumes. In 1986, the volume Periodontium, written by Hubert E. Schroeder of Zurich. appeared in this series (volume VIS, 418 pages).
