The author studied the magnification ratio of teeth length in orthopantomogram
through intraoral film taken by standardized paralleing technique.
In this study, intraoral radiograph and orthopantomogram were taken in 2 cases of
dry skull and 36 adults (504 teeth).
The obtained results were as follows:
1. In case of dry skull, the magnification ratio of standard films was 4.6% to 5.9%
and that of Orthopantomograph 5 was 15.1% to 33.1%. The magnification ratio of to the
standard film was 9.2% to 26.5%
2. In case of adults, the magnification ratio of Orthopantomograph 5 to the standard
films was 9.5% to 24.6%.
3. There were no significant difference in magnification between left and right.
4. Anterior teeth had lesser magnification than posterior teeth.
5. It was considered that teeth length showed in Orthopontomograph 5 was magnified
15.4% to 31.3% than actual teeth length.
