This study purports to make in consideration of the recent xeroradiographic
development an exact analysis, by comparison, of conventional cephalometry and
xeroradiographic cephalometry that are indispensably utilized in the field of orthodontics
as a means of cephalometric measuring
For that purpose attached to ten landmarks on a dry skull was a lead ball, a
radio-opaque substance, and projected X-ray beam one time each by means of the two
methods, and then ten times each without change of locations of the skull, in the state
in which the lead ball was removed. These data were committed to ten dentists for
tracing to determine a difference between the same kind of cephalometrics. A
computerized statistic analysis of the data shows findings, as follows :
1. Conventional cephalometry shows higher accuracy in Nasion, as compared with
xeroradio-graphic cephalometry.
2. Xeroradiographic cephalometry is found more accurate in Anterior Nasal Spine, 'A'
Point, Pogonion, Gonion, Porion, Prosthion and Orbitale than conventional cephalometry.
3. There is no difference between both methods in Basion.
4. At test between the two methods by all the dentists reveals that xeroradiographic
cephalometry is more accurate than conventional cephalometry.
