Abstract

The general purpose of this study was to determine whether orthodontists could differentiate among extraoral profile images imported into the Dolphin Imaging software and viewed on a computer monitor and as prints. The images were obtained by using different digital cameras and different compression settings. Twenty-two orthodontists were asked to evaluate extraoral profile images of the same individual taken by using a scanned 35-mm slide and two digital cameras (Nikon 990 and Fujix DS-220) at different resolutions. For images imported into Dolphin Imaging v. 7.0, the following minimum digital image sizes were considered acceptable: (a) Nikon 1024 × 768 basic compression setting (80 kb), printed ABO size image; (b) Nikon 1024 × 768 normal compression setting (135 kb), presentation-size printed images; and (c) Nikon 2048 × 1536 normal compression setting (500 kb), monitor-displayed images. Of the digital camera images, the Nikon 2048 × 1536 fine compression setting (750 kb) consistently received the highest Likert scores and acceptance scores for diagnosis, presentation to peers, and to other orthodontists for all sets of images.
