Abstract

Terahertz radiation is a part of electromagnetic spectrum that lies between infrared and microwaves. This technology is non-invasive and non-ionising radiation is used for the imaging purpose thus causes no damage to biological tissues. Terahertz waves have an inherent sensitivity to the water content. Thus, different biological tissues have different unique absorption spectra, thus making terahertz more attractive and promising for biomedical applications and can provide complimentary information to existing imaging modalities. This article reviews this novel imaging technique and its application in dentistry.
