ENDOS AC/ACP - CE

9.2

Typical faults caused by wrong positioning

•

X----rays with extended or shortened images

rays with extended or shortened images

The X-ray beam is not perpendicular to the bisecting line of the angle
formed by the longitudinal axis of the tooth and by the film.

•

X----rays with extended apex of the tooth

rays with extended apex of the tooth

Probably caused by excessive folding of the film in the patient’s
mouth.
