This document discusses the bisecting angle technique for intraoral radiography. It explains that the bisecting angle technique involves positioning the x-ray beam perpendicular to the long axis of the tooth by bisecting the angle between the tooth and the film. The document notes that proper horizontal and vertical angulation is needed to avoid issues like overlap or shortening/lengthening of teeth. It concludes with a thank you.

7. Rules of the Technique

14. Overlap
Is the superimposition of part of one tooth with part of
adjacent tooth If the horizontal angulation is not aligned
properly

19. Shortening or
lengthening of the
teeth depend on the
vertical angulation
Increase vertical
angulation decrease
the length of teeth
and vise versa

21. Film cone-cut
X-ray Beam not cover the entire film lead
to white area formation on the film
