ABSTRACT
To evaluate the variation in vertical magnification of digital panoramic machine Kodak 8000 Panoramic System in relation to different regions of maxillary and mandibular edentulous arches and to compare this variation in magnification. The study sample of 40 patients was divided into 2 different groups (20 each) depending upon the two different diameters of metallic spheres i.e., 3mm & 6mm used as radiographic reference. Each group was further subdivided into 2 subgroups depending upon the arch of placement of metallic sphere. The metallic spheres were placed in 4 different regions of maxilla and mandible. Digital panoramic radiograph was obtained and was subjected for measurement using Trophy Dicom Software. Data was analyzed statistical analysis by paired “t” test and student “t” test. The present study has established that there is variation in magnification both in vertical and horizontal direction for maxilla and mandible. In maxillary arch vertical magnification rate shows lowest values for 3mm spheres in right posterior, right and left anterior regions. In mandibular arch vertical magnification shows lowest values for 3mm spheres in right and left posterior, right anterior regions. The vertical magnifications in posterior regions were higher than anterior region. On comparing the magnification of maxilla and mandible, values were higher in maxilla. The study concludes that radiographic reference objects (use of metallic spheres) can be used as a steady method for radiographic assessment in edentulous patients, as there is variation in the magnification in both maxillary and mandibular arch area specifically.
