I discovered an article discussing differences in expansion rates ranging from 0.6% to 2.3% among devices. Previously, we noted greater variations. From a dental radiology perspective, cephalograms can enlarge by 10% due to a standard distance of 5 feet. We need to include citations like Dibbets 2002, which discusses magnification of 8.6-12.8%, and support from Dibbets & Nolte's findings of 11.4%, as well as Olmez's measurement of 14.6%. Let's finalize our answer!
