To investigate the effect of bulk-fill resin based composite materials on cuspal deflection in large slot mesio-occlusal-distal cavities (MOD) in premolar teeth. Methodology: Thirty-two sound maxillary premolar teeth with large slot MOD cavities were distributed to four groups (n=8). Three groups were restored with bulk-fill resin composite materials (Tetric EvoCeram, x-tra fil, and Sonic Fill, respectively) in a single increment. The conventional composite group, Filtek Z100, was used to restore the cavities in 2mm increments. Cusp deflection was recorded post irradiation using a Nikon measurescope UM-2 (Nikon, Tokyo, Japan), by measuring the changes in the bucco-palatal width of the premolar teeth at 5 minutes, 24 hours, and 48 hours after completion of the restoration. The cuspal deflection was obtained by recording the difference between the baseline measurements and the other measurements for each tooth. Results: Cuspal deflection was significantly higher in Conventional Composite than in Tetric EvoCeram Bulk Fill (p=0.0031), x-tra Fil Bulk (p=0.0029), and SonicFill Bulk (p=0.0002). There was no significant difference in cuspal deflection for Tetric EvoCeram Bulk, X-tra Fil Bulk, and SonicFill Bulk Composites. Conclusions: All the investigated bulk-fill resin composites exhibited cuspal deflection lower than conventional resin composite. One of the aims of research and studies on the resin composite materials is improving their clinical longevity, and simplifying their use. For that purpose bulk-fill materials are considered promising materials and further clinical studies should be conducted.

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.

The history of use of dental materials and biomaterial dates back to the BC era, but the real advances in this field have occurred since the 19th century, due to the invention and understanding of new materials. These advances have been due to the continuous quest for new materials and new technologies used for the design and fabrication of new and novel materials, and, in particular, the understanding of new materials with innovative clinical applications. These have only been possible due to interdisciplinary research of a translational nature, where physicians, surgeons, dentists, and materials scientists work together for a common and targeted goal. It is important for clinicians to understand the needs of the patient, who translates those needs for the materials scientist to develop an implant to improve the quality of life for the patient. Once the chemical, physical, mechanical, and biological properties of the materials are well understood, then these materials can be tailored to provide specific clinical applications. Development in the field of tissue engineering and regenerative medicine has only been possible due to work from this partnership. This Special Issue will provide an excellent forum to bring together different communities and publish research of a high caliber, which will be beneficial to healthcare.

Resin materials are broadly used in dentistry for almost all indications, and they will gain even more importance in the future. Especially the increasing performance and efficiency of the CAD/CAM technology and 3D-printing open possibilities to use resins which were not used up to now in dentistry. Besides dentists, dental students or dental technicians, there are many other specialists such as researchers, material scientists, industrial developers or experts of adjoining professional disciplines who are technically engaged in dental resins. The "Expert Level" is the third book of the series "Dental Resins - Material Science & Technology". The "Expert Level" includes all information and data presented in the "Basic Level" and "Advanced Level" of this series, but enormously expands the knowledge base. From a total database of 8.198 references, 1.707 were selected and used for this textbook. It comprises more than 1,000 manuscript pages, 384 figures and 124 tables. The "Expert Level" describes very accurately and comprehensively all details of the material science and technology of dental polymers and composites. Furthermore, their production methods and applications are discussed in detail. Therefore, this book is a unique treatise of the complete present knowledge about dental resins and dental resin composites. This includes the discussion of the - raw/starting materials together with the explanation and presentation of their chemical structures and properties, their CAS Numbers and the names of the manufacturers. - amounts of the raw/starting materials usually used to formulate the finished products. - important material and toxicological properties of the starting materials and the finished products. - detailed description of the production processes of essential starting materials such as the syntheses of essential monomers, the silanization of inorganic fillers or the manufacturing of unfilled and filled splinter polymers. - detailed description of the formulation and the properties of the finished products. Furthermore, for many commercial endproducts rather detailed formulations as well as the exact production processes are described. All ISO standards that are relevant for dental resins are listed, too. Furthermore, many essential methods to test the mechanical, chemical and toxicological properties are also presented and explained. The "Expert Level" enables every scientist with a good chemical knowledge not only to understand how dental polymers function, but also to develop new and improved products.

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
