This book was released on 2012 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: In vivo and in vitro degradation of resin-dentin interfaces can occur and accounts for poor clinical performance of adhesive dentin interfaces/restorations. Interfacial degradation results from several factors, to include, but not limited to: water sorption, hydrolysis of ester linkages of methacrylates resins, and activation of endogenous dentin matrix metalloproteinases (MMPs) in non-infiltrated collagen fibrils. Reduction of collagenolytic and gelatinolytic activity in dentin has been shown to be effective both in vivo and in vitro upon application of proteases inhibitors, such as chlorhexidine. This study compared the in vitro durability of resin-dentin bonds using microtensile testing over 12-month of water storage among five adhesive systems, including an experimental adhesive system, which had 2% chlorhexidine incorporated into the material. The results showed that all adhesive systems had a significant decrease in bond strength after 6 months, and that this reduction in bond strength was not significant different among the five adhesive systems studied. It is possible that chlorhexidine might have its inhibitory activity against MMPs lost or reduced due to chemical interaction with the adhesive system components. Also, to assess resin-dentin bonds degradation process, laboratorial studies use long-term water storage, which is labor-intense and time consuming process, therefore this study tested the possibility of accelerating the resin-dentin degradation process using water storage at 50° C.A significant reduction in microtensile bond strength occurred for specimens after 12-month storage at 50° C. The higher temperature may have increased the rate of water sorption and hydrolytic activity within the polymer network leading to adverse consequences to the interface.

Download or read book Dental Composite Materials for Direct Restorations written by Vesna Miletic and published by Springer. This book was released on 2017-11-25 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers both basic scientific and clinically relevant aspects of dental composite materials with a view to meeting the needs of researchers and practitioners. Following an introduction on their development, the composition of contemporary composites is analyzed. A chapter on polymerization explains the setting reactions and light sources available for light-cured composites. The quality of monomer-to-polymer conversion is a key factor for material properties. Polymerization shrinkage along with the associated stress remains among the most challenging issues regarding composite restorations. A new classification of dental composites is proposed to offer more clinically relevant ways of differentiating between commercially available materials. A review of specific types of composites provides an insight into their key issues. The potential biological issues of dental composites are reviewed in chapters on elution of leachable substances and cariogenicity of resin monomers. Clinical sections focus on material placement, finishing procedures, and the esthetics and clinical longevity of composite restorations. Bonding to tooth tissues is addressed in a separate chapter, as is the efficiency of various composite repair methods. The final chapter discusses future perspectives on dental composite materials.

Download or read book Biochemistry of Collagen written by Gopalasamudram Ramachandran and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collagen is a fascinating protein not only because of its ubiquitous occurrence in multicellular animals, but also because of its unique chemi cal structure. As the predominant constituent in bone, cartilage, skin, tendon, and tooth, it is not surprising that collagen is of interest to anatomists, biochemists, biomedical engineers, cell biologists, dermatolo gists, dental surgeons, leather chemists, orthopedic surgeons, physiologists, physicians, zoologists, and a host of others. This book was planned to provide an up-to-date comprehensive survey of all aspects of biochemistry of collagen. The recent discovery of genetically distinct collagens with tissue specificity has opened a new era in collagen biochemistry, and Karl Piez discusses this in the opening chapter on primary structure. In the next chapter, Ramachandran and Rama krishnan deal with the molecular structure of collagen, placing special emphasis on the conformational aspects of its polypeptide chains. Follow ing the consideration of primary and secondary structure of collagen, the three-dimensional arrangement of collagen molecules in the fibrils is covered by Miller in Chapter 3. Collagen is generally in the insoluble state in the living organism due to the cross-linking of individual molecules, and Tanzer describes the various aspects of this cross-linkage in Chapter 4. The biosynthesis of collagen is discussed in depth by Prockop and his colleagues.

Book excerpt: This book reviews the available information on bacterial disinfection in endodontics, with emphasis on the chemical treatment of root canals based on current understanding of the process of irrigation. It describes recent advances in knowledge of the chemistry associated with irrigants and delivery systems, which is of vital importance given that chemical intervention is now considered one of the most important measures in eliminating planktonic microbes and biofilms from the infected tooth. Recommendations are made regarding concentrations, exposure times and optimal sequences. Possible complications related to the use of the different solutions are highlighted, with guidance on response. In addition, clinical protocols are suggested on the basis of both clinical experience and the results of past and ongoing research. Throughout, a practical, clinically oriented approach is adopted that will assist the practitioner in ensuring successful endodontic treatment.
Download or read book Endodontic Prognosis written by Nadia Chugal and published by Springer. This book was released on 2016-12-24 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as a clinical guide to help the practitioner improve endodontic treatment outcomes. It focuses on the various factors affecting the prognosis of endodontic treatments and on their impact on short-term and long-term results. The text incorporates up-to-date knowledge, techniques and treatment protocols. Each chapter has been carefully chosen to address either foundational knowledge or a select aspect of endodontic treatment.
