Book Description
La rétention des deuxièmes molaires permanentes, bien que rare, devient un phénomène de plus en plus fréquent. Elle peut être liée à des obstacles mécaniques ou des défauts intrinsèques du mécanisme d’éruption (PFE: Primary Failure of Eruption décrit par Proffit et Vig en 1981). De brefs rappels de terminologie permettent d’utiliser le vocabulaire approprié. Ce travail reprend en détail les connaissances actuelles des phénomènes d’éruption, ainsi que les différentes voies de recherche, la voie RANK/RANKL/OPG au niveau du follicule dentaire est particulièrement intéressante. Puis, ce mémoire reprend les données des principales études réalisées sur les défauts d’éruption depuis les années 70. Ensuite, tous les éléments diagnostic sont repris de manière détaillée afin de cerner précisément l’anomalie, ce qui conditionnera les choix thérapeutiques. Notamment, des mutations du gène PTH1R ont été mises en évidence dans les cas de PFE héréditaire. Un arbre décisionnel permettra de distinguer: retard d’éruption, impaction (Mecanical Failure of Eruption), et rétention primaire ou secondaire associée à une PFE type I, II ou III (?) Un certain nombre de cas illustre ce propos. Pour certains des échantillons tissulaires ont été La thérapeutique est très brièvement évoquée et fera l’objet d’un autre mémoire.

Book Description
In their contribution to the first edition of this Handbook, entitled "The Teeth," LEHNER and PLENK (1936) discussed the tissues constituting the "perio dontium" rather briefly. In contrast to the detailed paragraphs dealing with, for example, enamel and dentine, the section (about 40 pages and 20 illustra tions, mostly drawings) devoted to periodontal tissues failed to provide a factual review and summary of the contemporary knowledge and latest developments in research on the various components of the periodontium. Instead, much of the text was an attempt to arrive at conclusions from often purely semantic speculations, playing the various schools of thought against each other, provid ing arguments in favor of the authors' views and arguments for the feasibility and probability of accepting or rejecting the often diverse opinions, while the reader was referred to the already existing literature for factual details. Since 1936, however, factual details ofthe structural biology of the periodon tal tissues, i. e. their development, structure, function, and physiology, have been greatly extended and have been internationally accepted. With much less opin ionated belief to cope with, this knowledge has formed the solid foundation upon which diagnosis, prevention, and treatment in the fields of clinical perio dontology, modem orthodontics, and re- and transplantation procedures of teeth have been built.

Book Description
This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.
