Incidence X-ray beam – Vertical angle
To get a real image of the tooth, the X-ray must be perpendicular to the
bisecting line of the angle formed by the longitudinal axis of the tooth
and by the film.
After positioning the X-ray beam and the patient’s head according to
these criteria, it is possible to apply an average vertical incidence for
each area. The incidence angle of the X-ray beam can be correctly
measured by the graded scale applied to the tubehead.
