Book Description
Este trabalho apresenta a distribuição de tensões em uma dentina radicular restaurada com pinos intra-radiculares confeccionados de diferentes de materiais. Dois modelos bi-dimensionais de um incisivo central superior com paredesdentinárias radiculares de pouca espessura, incluindo seus elementos de suporte, foram criados com a ajuda do programa AutoCAD 2000. O Modelo 1 representou um dente despolpado, com obturação radicular de guta-percha e restaurado com um pino intra-radicular fundido e uma coroa de cerâmica pura. Este modelo foi utilizado para as análises de pinos de ouro e de zircônia. O Modelo 2 foi similar ao primeiro, porém adotou-se um pino cilíndrico centralizado na cavidade radicular e preenchido com resina composta, sendo utilizado para as análises de pinos pré-fabricados de fibra de vidro e fibra de carbono. A simulação numérica foi realizada pelo software ANSYS 7.0, sendo os modelos carregados com uma força de 100 N em angulações de 45o e 180o em relação ao eixo longitudinal do dente. Os resultados mostraram que, em todos os modelos, as tensões se concentraram na terminação apical do pino, indicando que esta é uma região critica da raiz, podendo a geometria do pino influenciar no risco de fratura da mesma. Nos pinos fundidos, caracterizados por uma maior rigidez elástica, as maiores tensões se concentraram no próprio pino, preservando a dentinaradicular na sua porção média e cervical e, portanto, se mostrando mais eficientes no caso de raízes desgastadas. Já nos pinos pré-fabricados, observou-se uma distribuição de tensões de forma mais homogênea pelo dente e um menor nível de tensões no pino, preservando o material restaurador. Entretanto, a dentina radicular foi exposta a maiores carregamentos mecânicos.

Book Description
This book offers a comprehensive and up-to-date overview of the restoration of teeth retained through root canal treatment, from the perspective of adhesive dentistry. The challenge of adhesion to root dentin is first explained and guidance provided on assessment of the restorability of endodontically treated teeth. The types of prefabricated passive post are then described in detail. The advantages and disadvantages of each type are outlined, with identification of the factors that influence post selection. Further topics include the ferrule effect, evidence‐based clinical applications of fiber posts and new methods to lute fiber posts to the root canal without dentin adhesives. In addition, frequent myths are identified and dispelled. All aspects are illustrated with clinical and laboratory images, diagrams and high-resolution electron microscopy photographs.

Book Description
Traditional dental materials such as metals and ceramics have a number of disadvantages such as cost and the significant damage caused in grinding to make space for such reconstructions. Fiber-reinforced composites (FRCs) are a novel group of dental materials characterized by fibrous fillers that are being increasingly used in place of traditional prosthodontic materials. They allow fabrication of minimally invasive, lightweight, durable and biocompatible restorations. This book will provide clinicians and students with theoretical and clinical guidelines to use the FRCs for dental applications. The book begins with an introduction to the fundamentals of FRCs in dentistry. Further chapters cover the treatment possibilities, fabrication and application procedures of FRCs, followed by information on care and maintenance. Explores the mechanism of function of fibre-reinforced composites Presents comprehensive information on the expanding field of fibre-reinforced composites and their increasing use in dentistry

Book Description
During last couple of years there has been an increasing recognition that problems arising in biology or related to medicine really need a multidisciplinary approach. For this reason some special branches of both applied theoretical physics and mathematics have recently emerged such as biomechanics, mechanobiology, mathematical biology, biothermodynamics. This first section of the book, General notes on biomechanics and mechanobiology, comprises from theoretical contributions to Biomechanics often providing hypothesis or rationale for a given phenomenon that experiment or clinical study cannot provide. It deals with mechanical properties of living cells and tissues, mechanobiology of fracture healing or evolution of locomotor trends in extinct terrestrial giants. The second section, Biomechanical modelling, is devoted to the rapidly growing field of biomechanical models and modelling approaches to improve our understanding about processes in human body. The last section called Locomotion and joint biomechanics is a collection of works on description and analysis of human locomotion, joint stability and acting forces.

Book Description
This book is a comprehensive guide to BiodentineTM, an innovative biocompatible and bioactive material based on pure tricalcium silicate that can permanently replace dentin and can also serve as a temporary enamel substitute. Although BiodentineTM has been widely used across the world for the past decade, this is the first book to be devoted to its properties, interactions with the soft and hard tissues, and its multiple clinical applications. The coverage encompasses applications in primary and permanent teeth, in specialties as diverse as restorative dentistry, endodontics, paediatric dentistry, dental traumatology, and prosthetic dentistry. BiodentineTM application both in vital pulp therapy and endodontic procedures is illustrated and clinical step by step protocols are provided. The book provides a detailed update on BiodentineTM use to preserve the pulp vitality in direct/indirect pulp capping, pulpotomy and irreversible pulpitis treatment. It also details BiodentineTM use for non-vital teeth treatment in indications such as root/furcation perforation repair, apexification as well as in regenerative endodontic procedures. BiodentineTM: Properties and Clinical Applications will be a rich source of guidance and information for all dentists as well as dental students and academics.
