Available in PDF, EPUB and Kindle. Book excerpt: L'odontologie conservatrice a connu une véritable révolution avec l'avènement de la dentisterie adhésive et le développement des résines composites associé au collage aux tissus dentaires. L'apparition il y a 20 ans des résines composites fluides a élargi encore les possibilités thérapeutiques des praticiens. La mise sur le marché d'un grand nombre de résines composites qui diffèrent par leur nature matricielle et par le type, la taille et la proportion des charges incorporées associée au manque d'informations des fabricants sur les compositions exactes de leurs produits empêchent les praticiens de réellement connaitre les caractéristiques des matériaux qu'ils utilisent. L'hyper-caractérisation in vitro desdits matériaux est une voie importante pour avancer dans la compréhension de leur comportement. Afin de juger de l'impact de la variation du taux de charges dans le comportement mécanique et physico-chimique des résines composites fluides, nous avons étudié deux groupes de matériaux : un premier groupe constitué de résines composites fluides expérimentales à matrice commune et à taux de charges variable et un deuxième groupe composé de résines composites fluides disponibles dans le commerce. Pour chacun de ces matériaux après la détermination du taux de charges par la méthode de la calcination, l'évaluation des caractéristiques rhéologiques (viscosité complexe et module de conservation), la mesure de la micro-dureté (micro-dureté Vickers), la contraction volumétrique de prise selon la méthode de la déflexion d'une lame de verre, l'analyse thermo-mécanique dynamique en flexion (module de conservation, module de perte, facteur d'amortissement) ainsi que les capacités d'absorption d'eau et de solubilisation (détermination par différentiel de gravimétrie après immersion dans différents milieux) sont autant de facteurs potentiellement influencés par ledit taux de charges qui ont été étudiés. Si le taux de charges devrait clairement faire partie des critères de choix du praticien tant il apparait influant sur les plans mécaniques et physico-chimiques, il apparait qu'un taux de charges élevé ne représente pas une garantie suffisante pour répondre de façon optimale au cahier des charges du matériau d'obturation idéal. L'emploi de résines composites fluides déformulées à taux de charges variable permet d'évaluer le rôle de la phase dispersée, pour autant, l'étude en parallèle de matériaux commerciaux met en lumière l'influence de la nature matricielle et des différentes entités monomériques entrant dans la structure polymère.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les résines composites fluides et ultrafluides font désormais pleinement partie del'arsenal thérapeutique du chirurgien dentiste.Après un rappel sur l'historique de ces résines composites, leur composition et leurs propriétés physico-chimiques, nous avons détaillé les différentes indications cliniques de ce type de résine.Dans une seconde partie, cette thèse aborde plus particulièrement les scellements prophylactiques des sillons, puits et fissures ; leurs indications cliniques et leur protocole de mise en place. Ces matériaux, une fois déposés, vont être soumis à l'environnement buccal très complexe qui est détaillé en troisième partie. Dans un tel milieu, les résines composites et notamment les résines composites fluides et ultrafluides vont absorber et vont se solubiliser ; ce qui va à terme entraver leur pérennité. Le but de la quatrième partie est d'étudier in vitro, selon le cadre normatif ISO 4049, l'absorption et la solubilité de deux résines fluides et de deux résines ultrafluides placés en immersion dans cinq milieux différents (eau distillée, acide lactique, acide citrique, salive artificielle et Coca Cola).

Download or read book Diseases of the Salivary Glands Including Dry Mouth and Sj gren s Syndrome written by Isaäc van der Waal and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both the major and minor salivary glands can be the site of a wide variety of diseases and functional disturbances. This monograph covers both the common lesions and conditions of the salivary glands as well as the rare ones. Much attention is given to the problematic complaint of dry mouth and the even more cumbersome diagnostic aspects of Sjögren's syndrome. Emphasis is on the clinical aspects and the management of the various disorders. The vast experience of the authors is reflected in their clear and concise style. The illustrations are well chosen and updated references are provided, where appropriate.

Download or read book The Story of Crass written by George Berger and published by . This book was released on 2009 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-depth interviews with the main movers in the punk rock movement--Crass members Penny Rimbaud, Gee Vaucher, and Steve Ignorant--detail the face of the revolution founded by these radical thinkers and artists. When punk ruled the waves, Crass waived the rules by putting out their own records, films, and magazines and setting up a series of situationist pranks that were dutifully covered by the world's press. Not just another iconoclastic band, Crass was a musical, social, and political phenomenon: commune dwellers that were rarely photographed and remained contemptuous of conventional pop stardom. As detailed in this history, their members explored and finally exhausted the possibilities of punk-led anarchy. This definitive biography of the band not only gives backstage access to their lives, philosophies, and the movement that followed, but also to never-before-seen photographs and rare dialogues.

Download or read book Medical Traditions written by Alain Touwaide and published by de Gruyter. This book was released on 2021-12-31 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medical traditions encapsulate the knowledge of life, health, nutrition, diseases and their treatment patiently assembled by populations over a long period of time in the past, carefully handed down through generations, and subsequently recorded in writing and preserved in books now scattered in libraries across the world. Rarely the object of a specific study, they are approached here as a field in its own right. The present essay explores such key topics as the impact of tradition approach on medical historiography, the relation between written documents and practice, and the transmission of knowledge across time and cultures with its possible modifications and their processes and causes. Though based on a decade-long close scrutiny of the Greek medical tradition, it establishes parallels with other traditions, and invites not only to do comparative study, but also to apply to other traditions the approach proposed here. By laying down the foundations for a fresh analysis of ancient medical knowledge as a discipline, Medical Traditions - Exploring the Field will be a reference for any scholar interested in the medical record of the past, be it for the sake of history or for renewed applications in present day.
