[[File:Bisecting angle technique.jpg|right|200px|thumb|Bisecting angle technique: The cone of the dental xray generator is positioned at ninety degrees to a line (bottom spatula) that bisects the long axis of the film and the long axis of the tooth (top spatula) being radiographed.<small>''© Lisa Milella 2013''</small>]]
 
When radiographing [[:Category:Teeth - Anatomy & Physiology|teeth]] other than the mandibular [[Dental Formula - Dog#Premolars|premolars]] and [[Dental Formula - Dog#Molars|molars]] it is not anatomically possible to position the film parallel to the [[Enamel Organ#Root|tooth root]]. The bisecting angle technique uses a principle of geometry (the two sides of an isosceles triangle are equal in length) to prevent image elongation or foreshortening .

*Dogs - full-mouth radiographs are encouraged, especially at first examination. If this is not possible then radiographs should be taken where indicated based on the findings during the [[Conscious Oral Examination|clinical examination]].
