ABSTRACT
Nanoscience and nanotechnology have developed in such a way that it has already been used in several areas and incorporated as “nanothings” in our daily lives. This “nanoworld” deals with science and technology at the nanoscale, which means materials with at least one dimension less than 100 nm, affecting their properties when compared to their bulk equivalent. Nanotechnology in dentistry, or nanodentistry as it became known, is a growing area that is providing exceptional advances. This chapter deals with the present status of OCT applied to nanodentistry. From the point of view of imaging techniques, nanomaterials of different constituents and shapes have already played an important role, from enhancing the contrast of the acquired OCT imaging, to exploiting dielectric and metallic nanoparticles as optical clearing agents. Towards the end of this chapter, we will discuss how it is possible to manage the OCT technique to provide imaging below the micron-size spatial resolution (down to 10’s–100’s nm).
