title: Computerized Analysis of Digital Photographs for Evaluation of Tooth Movement.
abstract: OBJECTIVE
  Various methods have been introduced for evaluation of tooth movement in orthodontics. The challenge is to adopt the most accurate and most beneficial method for patients. This study was designed to introduce analysis of digital photographs with AutoCAD software as a method to evaluate tooth movement and assess the reliability of this method.
  
  
  METHODS
  Eighteen patients were evaluated in this study. Three intraoral digital images from the buccal view were captured from each patient in half an hour interval. All the photos were sent to AutoCAD software 2011, calibrated and the distance between canine and molar hooks were measured. The data was analyzed using intraclass correlation coefficient.
  
  
  RESULTS
  Photographs were found to have high reliability coefficient (P > 0.05).
  
  
  CONCLUSIONS
  The introduced method is an accurate, efficient and reliable method for evaluation of tooth movement.
