ABSTRACT
Position the patient so that the area of interest is convenient to the radiographic beam. In general, this is where the dental arch to be imaged is 'up'. Position the film/sensor/plate in the mouth so that the entire tooth is covered by the film/sensor. The 'simplified technique' as developed by Dr. Tony Woodward, does not utilize direct measurement of any angle, instead relying on approximate angles to create diagnostic images for almost every tooth. The roots of the maxillary canines are directly dorsal to the maxillary first and second premolars in dogs and the second and occasionally third premolar in cats. In addition, the symphysis interferes with parallel placement for the canines and incisors as well as the rostral mandibular premolars. For the incisors and mandibular canines rotate the beam rostrally 20 degrees. The straight lateral 45-degree bisecting angle will give a good representation of the mesial roots but they will be superimposed.
