Optic coherence tomography- A review

Abstract

OCT, a type of optical imaging non-invasive technique, reproducing the cross sectional 2D and 3D images of the tissues. It's based on low coherence interferometry, employs near infrared light (long wavelength) which penetrates into the scattering media (e.g.: oral tissues) and capture sub-micrometer resolution. Already an established medical imaging technique, it can be used for a wide range in dentistry for early detection of oral cancer (initial dysplastic changes), periodontal diseases, including dental caries. This paper reviews the understanding of the OCT, its basics, systems & setup, uses, limitations with the focus of it as a diagnostic imaging tool for oral lesions.
