The diagnostic value of a intra oral film is related to projecting technic and
interpretation.
The intra-oral film is a single plane representation of a three dimensional object,
therefore superimposition is inevitabilly present.
The purpose of this article is to show how foreign objects in the jaw may be
localized.
The author used double exposure technics, that are changed angulation of vertical or
horizontal to one film.
The obtained results are as fallow:
1. In the upper anterior region, the moving distance of the labially impacted reference
object was greater than that of the palatally impacted one.
2. In the upper molar region, the moving distance of the mesiobuccal root apex was
the greatest and that of palatal root apex was the shortest.
3. In the lower molar region, the change of the alveolar bone level in the buccal side
was greater than that of lingual side.
