Recent years has witnessed an unprecedented growth in area of Nano science. robotics is that branch of technology which specialises in designing, construction, operation and application of robots and use of robotics in dentistry is caving in. Nanotechnology at the same time has revolutionised all the aspects of science and endodontics. This book highlights the understanding of dental tissue at the nanoscale, enabling the precise design of materials and instruments with ultra fine architecture improvising the quality of treatment. Nano dentistry will make possible the maintenance of near perfect oral health through use of nano materials, biotechnology including tissue engineering and nano robotics. Following chapters will focus on various terminologies, properties of nano materials, their mechanism of action, its application in medicine and dentistry especially in Endodontics and the various challenges and future scope. Also it will focus on Nano robots, its role and dental and medical field and the scope of Endo Micro-Robotics.
