Objectives. LumenIQ\u27s ImageIQ software enhances conventional radiographs by adding 3-D depth. This study evaluated whether a preference exists for ImageIQ format versus conventional radiographs, determined whether ImageIQ format is as sensitive as 2-D radiographs when detecting existing periodontal defects and simulated periodontal defects. Methods. 34 dental practitioners compared 12 radiographic cases with ImagelQ format. A panel of evaluators classified periodontal defects from 2-D radiographs and ImageIQ images. Simulated periodontal defects were radiographed with various radiographic variables altered, converted to ImageIQ 3-D format, and measured to evaluate the ImageIQ format compared to the 2-D control. Results . ImageIQ format showed improved image clarity and detail over the 2-D. Changes in x-ray beam exposure time, beam angulation, and bone quality had no effect on the ImageIQ format. ImageIQ format improved the accuracy of periodontal defect classification by 14.3% over 2-D. Conclusions . ImageIQ may provide a reliable diagnostic alternative to conventional two-dimensional radiographs
