This book was released on 2014-07-31 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this book is to reduce endodontic failure, increase the success rate of endodontic treatment and decrease the percentage of tooth extraction so as to conserve a naturally compromised tooth structure as opposed to having a dental implant. The first study focuses on the possibility of having a filling material which could provide a tight seal with the desired properties. The in Vitro study targeted on elimination of microleakage by measuring the ability of the existing materials to obturate the root canal, 3 dimensionally using different obturation techniques. This was done by correlating the reading using the electrochemical machine and Micro CT Scan. This study adds value to the fact that the currently developed Nano HA based endodontic sealer is being produced locally in Malaysia thereby reducing the cost as compared to its imported counterpart. The third study consisted of testing the possibility of reinforcing over-flared root canal with Mineral trioxide aggregate (MTA) and also illustrated the pattern of root fracture. This development will definitely help economize the treatment thereby providing a good solution for young patients under 18 years of age.

This book was released on 2010-09 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shorttitle: The development and maintenance of apical seal is desirable and considered to be a major prerequisite to improve the outcome of root canal treatment. Basically, two materials are used in combination for the root canals filling; a semisolid material (gutta-percha) and a sealing cement. Many types and brands of endodontic sealers are commercially available, but none of them fully satisfy all requirements and able to provide a fluid- tight seal. To address this problem the School of Dental Sciences, USM, has prepared a new experimental nano HA-filled epoxy resin based endodontic sealer using a simple and inexpensive technique. Nano-HA is biocompatible, reactive and has capability to adhere to the dentinal tubules. Moreover, it promotes apical healing and is able to produce hermatic apical seal. Different filling techniques based on heated or preheated gutta-percha have been introduced to enhance three-dimensional filling of the root canal. Little is known regarding the apical sealing ability of the new experimental nano-HA sealer when used with different obturation techniques.

This book was released on 2019-11-11 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2016 in the subject Medicine - Dentistry, grade: A, , course: MDS, language: English, abstract: This book analyses different types of retrograde filling materials. The major goals of root canal treatment are to clean and shape the root canal system and seal it in 3 dimensions to prevent reinfection of the tooth. Although initial root canal therapy has high degree of success, failures can still occur after treatment. Recent studies reported failure rates of 14%–16% for initial root canal treatment. Lack of healing is attributed to persistent intraradicular infection residing in previously uninstrumented canals, dentinal tubules, or in the complex irregularities of the root canal system. The extraradicular causes of endodontic failures include periapical actinomycosis, a foreign body reaction caused by extruded endodontic materials, an accumulation of endogenous cholesterol crystals in the apical tissues, and an unresolved cystic lesion. This book is composed of ten chapters and begins with the need of root-end resection. The succeeding chapters deal with the method and concept of root-end resection, root end preparation to receive the material, ideal requirements of materials to be placed in the resected and prepared root-end. The concluding chapters describe various root-end materials available in the market so far and their properties, focusing on each individual material one by one, their advantages and disadvantages. This book will prove useful to Endodontists and Researchers in the field of endodontic surgeries & root-end filling materials. Also it would provide the undergraduate and postgraduate students an easy way of reference for covering a broad spectrum of Root-end filling Materials available today, in lucid and simple language.

Available in PDF, EPUB and Kindle. Book excerpt: "Currently, clinicians can choose from a wide range of root canal filling materials and techniques, some of which have been evaluated in this thesis. Methacrylate resin-based sealers suffer from polymerization shrinkage stresses. This limitation may partly be overcome by a two-step cementation procedure. This alternative placement technique results in an increase and homogenization of the adhesion of the material to intraradicular dentin. Subsequent research should aim at developing sealers with shorter setting times for clinical implementation and confirm the present proof of concept. It remains to be proven whether an increase in adhesion could be considered as a surrogate for improved sealing ability. With the used methodology, we could not demonstrate any association between the sealing ability and the adhesiveness of an adhesive root canal filling material. Using the low surface tension fluid transport method, the sealing ability of the single-cone technique, after post space preparation, was found to be material dependent, with the epoxy and methacrylate resins providing a better seal than the calcium silicate-based sealer. Roots canals filled with a single-cone technique using gutta percha and a calcium silicate-based root canal sealer were less porous than root canals filled with lateral compaction of gutta percha and the same sealer. Delamination and tearing defects could be observed in root canals filled with hydrogel-coated hygro-expandable cones and a calcium silicate-based sealer. Hydrogels are smart materials that may currently be inadequate for endodontic use with calcium silicate sealers. The use of simulated body fluids for testing the bioactive potential of calcium silicate-based fillings leads to the deposition calcium phosphate. This phenomenon may however be simply reflecting a thermodynamic process rather than expressing bioactivity potential. [...]"--Samenvatting auteur.

This book was released on 2010-09 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hermetic seal of the root canal system is a prime objective of successful endodontic therapy. However, the microleakage between the root canal filling and the cavity walls may adversely affect the success of root canal therapy . The rationale for root end filling is to prevent microleakage. However, none of the materials used provide an impervious seal. Subsequently the microleakage is responsible for the failure of the surgical endodontic procedure.

Download or read book Gutta Percha As Root Canal Obturating Material written by Geetanjali Bansal and published by LAP Lambert Academic Publishing. This book was released on 2012-05 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The root canal system has many variations in anatomy such as irregularly shaped canals, lateral and accessory canals, and a variety of fins which lead to difficulty in preparing the canals to form conducive to complete obturation with filling materials whenever a need for endodontic therapy arises. The final goal of endodontic treatment is to fill the entire root canal system and all its complex anatomic pathways completely and closely with non irritating hermetic sealing agents.The achievement of a "Hermetic seal" is often cited as the major goal of root canal treatment. As guttapercha is a benchmark for root canal obturation an attempt has been made in the form of a book to review the current dental literature of guttapercha and to discuss its forms, properties, its advantages along with its different techniques used for obturation of guttapercha.

Download or read book Obturation Techniques written by Jaidev Singh Dhillon and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obturation of the root canal system is an integral component in promoting periapical healing and preventing disease progression. The root canal filling material accomplishes this by reducing microleakage and entombing any inflammatory irritants. The effectiveness of a material to adequately seal the root canal space is established by its physical properties and handling characteristics. The gamut of materials run from tin, gold foil, cotton pellets, with various medicaments of wood, plaster, oxyphosphate of zinc, zinc oxide, paraffin, copper points, various metals, amalgam, silver cones, to the most popular, gutta-percha. Over the past century, numerous obturation materials and delivery techniques have been introduced in an attempt to obtain a microbiologic barrier within the confines of the root canal system. Different materials have their limitations and advantages. Thus numerous techniques have been proposed, experimented with and implemented to achieve the most dense obturations.

This book was released on 2011-08-01 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although numerous root canal filling materials are available, gutta-percha continues to be the product of choice, owing to its unique chemical and physical properties. Recently a new resin based system resilon epiphany has been introduced. It is used in combination with a self-etching primer to create a solid monoblock. Although the Epiphany sealer was primarily developed to be used in combination with polymer-based resilon points, the use of Epiphany in conjunction with Gutta Percha cones could offer a potential upperhand because gutta-percha is far economical than Resilon. This thesis work has compared various combinations of obturating materials to improve the fracture resistance of endodontically treated teeth.

Download or read book Obturation of the Radicular Spaces written by Anshu Chandurkar and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past era of dentistry, it was believed that, "It Is What Is Removed From the Canal That Is Important, Not What Is Put In." But with the evolution of endodontics & a better understanding of the root canal system, researchers have attributed failure of root canal therapy largely to incomplete obturation of the root canal system. Although the clinician has a variety of obturation techniques to choose from today, the quality of seal produced by either of them is questionable. One of the biggest challenges that faces endodontics in this millennium is to find a material that can form a leakproof seal that is bioinductive and promotes regeneration, or a "smart" material that can adapt to the ever-changing microenvironment of the canal system. This book is a compilation of the golden standards of obturating materials, types of root canal sealers, root canal filling techniques & the more current clinical data that are based on procedures performed with more advanced techniques. With the knowledge of these recent innovations, the future holds the promise of providing the most valuable thread of evidence connecting the patient & the clinician in delivering the oral health care.

Book excerpt: O propósito deste estudo in vitro foi avaliar a qualidade de obturações endodônticas em relação ao selamento apical e marginal, comparando duas técnicas de obturação: Condensação Lateral (CL) e Condensação Vertical (CV) daguta-percha aquecida. Foram utilizadas 40 amostras que foram submetidas à penetração passiva de solução de nitrato de prata a 50% e divididas em dois grupos. Para cada grupo de amostras infiltradas foi utilizada uma metodologiadiferente. O grupo 1, com cada metade das amostras obturadas com um tipo de técnica de obturação, foi preparado para microscopia Óptica (MO), processamento digital de imagens (PDI) e espectrometria de absorção atômica (EAA). O grupo 2, com metade das amostras obturadas por cada uma das técnicas, foi preparado para microscopia eletrônica de varredura (MEV). Através da MO e PDI, as amostras foram avaliadas quanto à qualidade das obturações, quantificando o percentual de guta-percha e cimento presentes. Através da utilização da EAA, a massa de prata infiltrada na obturação foi quantificada e finalmente, com o uso da MEV, a adaptação marginal dos materiais obturadoresàs paredes do canal radicular foi avaliada. Nas condições experimentais em que este trabalho foi conduzido e através da análise estatística, concluiu-se que houve diferença estatisticamente significante em relação ao selamento apical produzido pelas duas técnicas de obturação avaliadas e quanto à qualidade de preenchimento das obturações. Nas observações ao MEV, a CV mostrou uma melhor adaptaçãodo material obturador às paredes dentinárias quando comparada com a CL em algumas regiões do canal radicular.
