Nanotechnology: The future

The challenge to our profession today is to improve the quality of oral health while overcoming both extrinsic and intrinsic factors which may adversely affect our progress toward achieving this goal. Nanotechnology which is fast developing, its name reverberating in almost every field, is also making and is set to transform dentistry in a huge way. This article tries to give an insight of the application of nanotechnology in dentistry using both top down and bottom up approach, recent development of nano products with superior quality, helical rosette nanotubes as a bone substitute, surface treatment of implant, dentifrobot, improved diagnostic instruments, (biomarkers, stem cell imaging in MRI) precise drug delivery system, controlled radiation therapy and bio nano sensors for cancer treatment, the near to achieve future ground breaking realities of development of bionic mandible, nanorobots, respirocytes, microbiovore, cytorobots, karyorobots, their effect on dentistry and medicine, and the possible risk factors and the ethical concerns to be looked into for application of nanotechnology in dentistry.
