Verbesserungen in der Zahntechnik haben das Konzept der Fotografie zu einem leistungsstarken Ausdrucks- und Kommunikationsmedium umgestaltet. Die digitale Fotografie ist heute eine der h ufigsten klinischen Anwendungen der Computerisierung in der Zahnmedizin. Sie hilft bei der Entdeckung versteckter und unentdeckter Fehler in Z hnen und anderen Bereichen der Kavit t oder des L chelns. Die zahnmedizinische Welt besteht aus Mikrostrukturen, die sorgf ltig dokumentiert werden m ssen, um die Patientenaufkl rung, die Dokumentation und die Behandlung durchf hren zu k nnen. Dieser Beitrag befasst sich mit den wichtigen Anwendungen der Digitalfotografie in der Zahnmedizin und den m glichen Auswirkungen auf die Compliance der Patienten bei der Zahnbehandlung.

Les progr s de la technologie dentaire ont transform le concept de photographie en un puissant moyen d'expression et de communication. La photographie num rique est l'une des applications cliniques les plus courantes de l'informatisation en dentisterie de nos jours. Elle permet de d couvrir les d fauts cach s et non d tect s des dents et d'autres zones de la cavit ou du sourire. Le monde dentaire est constitu de microstructures qui doivent tre m ticuleusement document es afin d'assurer l' ducation du patient, la documentation du dossier et le traitement. Cette tude se concentre sur les applications importantes de la photographie num rique en dentisterie et sur l'impact potentiel sur l'observance des soins dentaires par les patients.

I miglioramenti della tecnologia dentale hanno ridisegnato il concetto di fotografia trasformandolo in un potente mezzo di espressione e comunicazione. La fotografia digitale una delle applicazioni cliniche pi comuni della computerizzazione in odontoiatria. Aiuta a scoprire difetti nascosti e non rilevati nei denti e in altre aree della cavit o del sorriso. Il mondo odontoiatrico costituito da microstrutture che devono essere meticolosamente documentate per poter eseguire l'educazione del paziente, la documentazione e il trattamento. Questa rassegna si concentra sulle importanti applicazioni della fotografia digitale in odontoiatria e sul potenziale impatto sulla compliance del paziente alle cure odontoiatriche.

Scientific Study from the year 2017 in the subject Engineering - Mining Engineering, grade: 2.0, Technical University of Clausthal (Department of waste disposal and Geomechanics), course: Applied rock mechanics, language: English, abstract: Determining the stresses that exist in the rock mass opening has been a significant area of research in mining for a long time. The main reason for this is the concern of roof collapse of the excavation due to overlying pressure from the rock mass. This thesis is concerned with the state of stresses that exist in the rock mass in 2 conditions: 1. Stresses in rock before the mine openings; 2. Altered state of stresses after the excavations are made. Theories have been formulated to calculate the pre-stressed state of the rock mass. But any sort of measurement invalidates the original condition of the intact rock. There are mainly 3 ways to study these different stress conditions in the rock mass: Analytical solutions using pre-defined mathematical equations; using numerical modelling to predict the stresses by duplicating the in-situ stress conditions; and in-situ measurements of the stress conditions in the rock mass. One of the first assumptions taken while doing the measurements is assume that the rock mass is elastic and homogenous (single layer). There are also assumptions where the rock is considered viscous, plastic or a combination of these. But for this research project, the first assumption is considered. This is done to ease up the subsequent calculations on the more complex characteristics of the rock mass. In this research project, the attempt is to do a comparison of the initial and final stressed conditions of the rock mass in a series of square and circular drifts between the analytical and the numerical solutions of the model. It must be noted that a completely accurate picture of the stress phenomena cannot be drawn because of the lack of knowledge of the physical properties of rock under field conditions.
