Abstract: The aim of this study was to innovate a standardized in vivo Photographic technique to assess the change in appearance and dimensions of white spot lesions present after orthodontic treatment before and after remineralization.
Subjects and Methods: Forty five children from 12 to 17 years old who had just finished their orthodontic treatment were selected from the Orthodontic Clinic Faculty of Dentistry Ain Shams University. The purpose of the study was clearly explained to the patients and they agreed by signing an “Informed Consent". The children were randomly assigned to either the MI plus or the control groups. MI plus paste was applied weekly per the manufacturer instructions in the Pediatric Clinic at Faculty of Dentistry Ain Shams University. Examination of white spot lesions was performed using the ICDAS II criteria and compared with the photographic assessment at the beginning of the study period as a baseline and every month for six months throughout the study. The white spot lesions as a percentage area of the visible labial surface of the tooth were calculated by image analysis using ADOBE PHOTOSHOP™ and Auto CAD 2007.
Results: Standardized photographic technique has been proved to be reliable, accurate and reproducible when carried out on digital images in comparison with direct clinical examination using the ICDAS II.
