Abstract :

Optical Coherence Tomography (OCT) is a new technology, which gives a 3 dimensional, non–invasive imaging modality which produce high–resolution images of a biological tissues in cross section. OCT is analogous to ultrasound imaging, except that it uses light from oadband laser light source instead of sound. In the year 1991, Huang and co–workers were first introduced OCT which was initially used for retinal imaging. Later in 1998, Colston et al were introduced OCT for dental applications. It can provide images of tissue in situ and in real time. OCT can be used where standard excisional biopsy is hazardous or impossible, to reduce sampling errors associated with excisional biopsy, and to guide interventional procedures. This review article focuses on principle and various applications in dentistry till date.
