SMART MATERIALS IN DENTISTRY

There is no single material in dentistry that is ideal in nature and fulfills all the requirements of an ideal material. As the quest for an ideal restorative material continues a newer generation of materials was introduced. These are termed as smart'' as these materials support the remaining tooth structure to the extent that more conservative cavity preparation can be carried out. These materials may be altered in a controlled fashion by stimulus such as stress temperature moisture pH electric or magnetic field. Some of these are biomimetic in nature as their properties mimic natural tooth substance such as enamel or dentin. The current dental materials were improvised in order to make them smarter. Understanding and using these advanced materials may make the difference between success and failure in today's intensely competitive world.
