Paper Abstract

The objective of this laboratory study was to evaluate the use of a swept-source optical coherence tomography (SS-OCT) as a diagnostic tool for dental caries. The carious molars were extracted from human volunteers and examined visually using conventional dental equipment without any magnification. SS-OCT observations were carried out on the same sites as where the conventional examination had been performed. The center wavelength of SS-OCT system is 1300 nm at a 100 kHz sweep rate. The results showed that SS-OCT could clearly create cross-sectional imaging of dental structures. Moreover, carious lesions could be detected and distinguished from normal tissues. In conclusion, the SS-OCT signal could be used as a marker for early caries detection.
