Abstract

Smart materials are those materials having properties which may be altered in a controlled fashion by stimuli, such as stress, temperature, moisture, pH, and electric or magnetic fields. Examples include piezoelectric materials, which produce a voltage when stress is applied or vice versa, shape memory alloys or shape memory polymers which are thermo responsive, and pH sensitive polymers which swell or shrink as a response to change in pH. Smart behavior occurs when a material can sense some stimulus from its environment and react to it in a useful, reliable, reproducible, and usually reversible manner. These properties have a beneficial application in various fields including dentistry. Shape memory alloys, zirconia, and smart seal are examples of materials exhibiting a smart behavior in dentistry. There is a strong trend in material science to develop and apply these intelligent materials. These materials would potentially allow new and ground breaking dental therapies with a significantly enhanced clinical outcome of treatments. The numerous applications they have been put to, no wonder tells us that these smart materials hold a real good promise for the future of dentistry. The aim of the presentation is to show how dentists and dentistry made use of these smart materials for benefits of their patients.
