    Optical Coherence Tomography for Detection of Experimentally Formed Enamel Cracks
    OBJECTIVES: The aim of this study was to investigate the use of swept-source optical coherence tomography (SS-OCT) for detection of experimentally formed infractions (cracks). METHODS: An SS-OCT (OCT-2000, Santec, Japan) system with a laser center wavelength of 1310nm was used. 10 porcine impacted premolars were subjected to impaction procedures by a steel rod plunging from the occlusal tip to create infractions. SS-OCT cross-sectional images and stereomicroscopic photographs of the surface at x10 magnifications were acquired for each sample before and after impaction. The focused light beam of SS-OCT was projected from three directions on the same plane; buccal or lingual ...
