    Clinical assessment of non carious cervical lesion using swept-source optical coherence tomography

    ( A ) We determined the attenuation coeffcient (μ t ) threshold of SS-OCT signal for the detection of demineralization (1.21) from in vitro study. DEM: demineralized dentin, sound: sound dentin. ( B ) Using the μ t threshold, we observed NCCLs in vivo to detect the demineralization in cervical dentin. SS-OCT scanning was performed along the red line. ( C ) SS-OCT image obtained along the red line in B. In SS-OCT, brightness of dentin beneath the NCCL was increased (arrow) compared with intact zone. The cervical dentin was slightly demineralized (μ t : 1.25). e: enamel, d: dentin, g: gingiva. Non-carious cervical lesions (NCCLs) involve various forms ...
