The quest for an "ideal restorative material" continued and a newer generation of materials came into existence which are termed as "smart'' as these materials support the remaining tooth structure to the extent that more conservative cavity preparation can be carried out. Some of these are also "biomimetic" in nature as their properties can mimic natural tooth structures such as enamel or dentin. Smart materials have revolutionized many areas of dentistry. These innovations in the material science have marked the beginning of an era of biosmart dentistry a step into the future So it's time to think "smart" and apply bio smart dentistry in our day-to-day clinical practice.
