This book lays emphasis on the application of nanorobots in dentistry. Nanorobotics is a technology, an excellent tool for future where the robots and machines are produced at a nanoscale built from individual atoms. Nanorobotics is emerging as a challenging field for dealing with microscopic objects at the molecular level and is used for both medical and dental application including the disease monitoring, diagnostic procedures, treatment, and prevention of oral and dental diseases while reducing the need for invasive procedures.
