Biocompatibility of dental materials has evolved into a comprehensive, complex, and independent discipline of dental materials science. Materials used in dentistry come into direct contact with the oral mucosa, the pulp, the periapical tissues & the hard tissues of the teeth. Due to the long-term contact, the materials should exhibit a high degree of biocompatibility. Only products with a proven biocompatibility should be used. In this book, the biocompatibility of endodontic materials has been discussed.

Science is presently undergoing a great evolution, taking humanity to a new era: the era of nanotechnology. Nanotechnology deals with the physical, chemical and biological properties of structures and their components at nanoscale dimensions. Nanotechnology is a novel field, which involves manipulation of matter at the molecular level, including individual molecules and the interactions among them. The use of this technology allow many developments in the health sciences as well as in materials science. Nanotechnology has been used to make a dental restorative composites that offers high...
