Book excerpt: Malgré les programmes de prévention instaurés dans la plupart des pays industrialisés, la maladie carieuse reste la pathologie bucco-dentaire ayant la plus haute prévalence dans le monde, touchant de 60 à 90 % des enfants scolarisés, et près de 100 % des adultes. Le xylitol, un édulcorant naturel de structure cristalline, est utilisé depuis la fin des années 1970 en Finlande et dans les autres pays nordiques pour promouvoir la prévention des caries. Lors de sa consommation, il est ingéré par les bactéries cariogènes buccales mais ne peut être transformé en acide, il est donc non-cariogène. Le blocage du métabolisme bactérien succédant à son ingestion lui conférerait, de plus, des propriétés anti-cariogéniques actives par inhibition des caractères de virulence et de la prolifération bactérienne. Ce travail consiste en une analyse critique la littérature disponible, afin de comprendre les différents mécanismes à l'origine de ces propriétés, et de préciser le champs d'action du xylitol ainsi que son intérêt véritable en santé publique dans la prévention de la carie.

Available in PDF, EPUB and Kindle. Book excerpt: Dans la société actuelle, la maladie carieuse est l'une des pathologies chroniques les plus répandues. Afin de réduire son incidence, plusieurs mesures de prévention ont été mise en oeuvre dont l'utilisation du fluor est la principale représentante. Depuis quelques années, les recherches se tournent vers d'autres produits dont le xylitol fait partie. Cet alcool de sucre est introduit dans de nombreux produits de la vie quotidienne, notamment les chewing-gums et certains produits d'hygiène buccodentaire. Cette scoping review a pour but de faire état des preuves disponibles concernant l'efficacité de l'utilisation du xylitol en odontologie préventive mais, aussi de faire le point sur l'information des chirurgiens-dentistes et des consommateurs. Ce travail de recherche sous forme de scoping review a pour but de faire le point sur la littérature scientifique disponible ces dix dernières années traitant de l'utilisation du xylitol en odontologie préventive. En incluant les divers travaux de synthèse et les articles originaux traitant de l'efficacité du xylitol mais aussi des études moins standardisées s'intéressant aux connaissances et aux comportements des professionnels et des utilisateurs. Cette thèse tente d'offrir une vision étendue des textes scientifiques disponibles. L'objectif de ce travail est de savoir s'il peut y avoir un consensus ou non sur l'utilisation préventive du xylitol et quelles sont les pistes nécessitant des recherches approfondies.

Download or read book Le xylitol dans la pr vention dentaire written by Marie Castaing-Debat and published by . This book was released on 2001 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: La carie dentaire résulte de la déminéralisation des tissus durs de la dent par les acides issus du métabolisme bactérien. Les lactobacilles en particulier transforment le glucose en acide acétique, en éthanol et surtout en acide lactique. Un geste de prévention bucco-dentaire consiste à substituer ce glucose cariogène par des produits considérés à faible potentiel acidogène tel que le xylitol. Le xylitol est un polyol en C5 auquel ont été attribuées depuis 30 ans de nombreuses propriétés : non acidogène, anticariogène, réducteur de plaque, reminéralisant et inhibiteur de la croissance bactérienne.Nous étudions in vitro le comportement de 20 souches de lactobacilles en présence de xylitol. Nous montrons qu'en fait les lactobacilles peuvent métaboliser le xylitol comme le montre la chute de pH consécutive à la culture de ces bactéries sur un milieu riche en xylitol. Nous expliquons ce fait par une sélection de souches résistantes au xylitol chez lesquelles a eu lieu une dé-répression enzymatique. Cette adaptation est fonction de la durée de culture préalable sur un milieu normalement concentré en xylitol ou en glucose. Enfin nous obtenons 100% de réponses positives, y compris chez des souches du groupe I (homofermentaires) décrites comme incapables d'un tel métabolisme. Nous concluons que si le xylitol est un produit aujourd'hui utile dans la prévention dentaire, à terme, l'adaptation des lactobacilles pourrait le rendre inefficace.
Download or read book Pit and Fissure Sealants written by Katrin Bekes and published by Springer. This book was released on 2018-02-27 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides wide-ranging information on current clinical and scientific knowledge on the various aspects of fissure sealing. Trends in the epidemiology of caries are first examined, followed by thorough description of the morphology of pits and fissures and types of sealant. The role of sealants in the prevention of caries is discussed. Diagnostic parameters are presented, along with step-by-step descriptions of clinical procedures for fissure sealing. Chapters are also included on alternative techniques of fissure sealing, sealing of carious fissures, and therapeutic fissure sealing. The final chapter in the book focuses on the cost effectiveness of the procedure. Tooth surfaces with pits and fissures are particularly vulnerable to caries development. Sealants were developed to help manage these sites of the tooth and safeguard the surfaces from decay. This book has been written by acknowledged experts in the field. It will be of value for all dental professionals seeking to deepen their understanding of current knowledge on the science and the clinical application of pit and fissure sealants.

Download or read book Multifunctional Oxide Based Materials From Synthesis to Application written by Teofil Jesionowski and published by MDPI. This book was released on 2019-09-03 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with novel aspects and perspectives in metal oxide and hybrid material fabrication. The contributions are mainly focused on the search for a new group of advanced materials with designed physicochemical properties, especially an expanded porous structure and defined surface activity. The proposed technological procedures result in an enhanced activity of the synthesized hybrid materials, which is of great importance when considering their potential fields of application. The use of such materials in different technological disciplines, including aspects associated with environmental protection, allows for the verification of the proposed synthesis method. Thus, it can be stated that those aspects are of interdisciplinary character and may be located at the interface of three scientific disciplines—chemistry, materials science, and engineering—as well as environmental protection. Furthermore, the presented scientific scope is in some way an answer to the continuous demand for such types of materials and opens new perspectives for their practical use

Download or read book Cariology for the Nineties written by William H. Bowen and published by University Rochester Press. This book was released on 1993 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental caries, despite significant reductions in some populations,continues to be a major public health problem, and is the most prevalentdisease affecting humans. However, even fundamental aspects of thepathogenesis of caries remain uncertain, calling for continuing scientific enquiry and the application of sophisticated techniques, from epidemiology to molecular biology. Although recent changes in the pattern of dental caries are identifiable, available data does not reveal whether, overall, caries is declining. The conference `Cariology in the Nineties', held at the University of Rochester in 1991, by focusing on the etiology, pathogenesis and prevention of dental caries, emphasised the need to co-ordinate research in monitoring populations worldwide, and to change the focus of research to reflect the changing epidemiology and patterns of dental disease. Contents: Keynote address; Epidemiolgy; Saliva; Teeth; Clinical studies; Microbiology/Plaque; Diet/Nutrition/Prevention. W.H. BOWEN is Professor and Chair, Department of Dental Research,University of Rochester. LAWRENCE A. TABAK is Professor of Dental Research and of Biochemistry, University of Rochester.

Download or read book Olfactory Cognition written by Gesualdo Zucco and published by John Benjamins Publishing. This book was released on 2012 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was conceived as a tribute to one of the founders of the psychological study of the sense of smell, Professor Trygg Engen. The book is divided into four sections. The first reunites the fields of psychophysics and the perception of environmental odours and discusses the impact of odours on beliefs and expectations. The second addresses cognitive processes in olfaction, how odours are interpreted, lexicalized, associated with contexts and remembered. The third focuses on the cerebral bases of olfactory awareness and the neuropsychological investigation of olfaction with special emphasis on olfactory dysfunctions, and the last concerns affective and developmental processes in olfaction. The aim in producing this book is that it will help promote further research in olfactory cognition and attract new inquisitive scientists to the field. The volume will be a useful resource for academics, students, and professionals who study olfaction, as well as to scientists who work in the domains of perception, cognitive neuroscience and environmental psychology more broadly.
