Obtaining intraoral photos using cross-polarisation photography
MIH lesion, tooth
A cross-polarisation filter suitable for our ring flash (Yongnuo YN-14EX TTL, China) was prepared and attached to the camera (Canon EOS 700D, Tokyo-Japan) before obtaining the intraoral photographs in order to minimize light reflection and to be able to observe the lesion borders more clearly. After the teeth were removed using a photo retractor, intraoral photographs of the treatment and control groups were obtained before; immediately after; and 1, 3, and 6 months after the application of the resin and were archived. Next, these images were analyzed using Image J (1.31o, National Institutes of Health, Bethesda, MD, USA) software, and the lesion areas of the teeth in the treatment group were measured in mmIntraoral photographs of a patient with MIH lesion in tooth #21 obtained using cross-polarization photography (
