(A) White-light and fluorescent images of the occlusal surface of the maxilla or mandible captured using a Qraycam Pro® (QP, AIOBIO, Seoul, Republic of Korea). (a, b) A trained examiner using a Quantitative light-induced fluorescence (QLF) system in a dark room to maintain the image quality. This device is equipped with a metal tube that blocks external light to prevent contamination of the fluorescent image. (c) White-light image (d) Fluorescent image. (B) (a, b) QLF images of the occlusal surface of the examined tooth captured using a Qraypen C® (QC, AIOBIO, Seoul, Republic of Korea). (c) White-light image (d) Fluorescent image. (C) QA2 version 1.25 (Inspektor Research system BV, Amsterdam, The Netherlands). QA2 provides the QLF parameters (ΔFmax, ΔFaver., ΔRmax, ΔRaver.) of the area of interest (AOI); (a, b) Quantitative analyses of QP and QC images, respectively.
