4

what number will the canine always

time

what is the only factor that changes when taking dental radiographs

x-ray film and long axis of tooth

what two things determine the bisecting angle

mandibular PM4 and caudal

what teeth can you use parallel technique with

bisecting angle

what technique do you use to image the incissors

bisecting angle

what technique do you use to image the maxillary molars

parallel

what technique do you use to image the mandibular molars

foreshortening

what happens when x-ray beam is perpendicular to the film instead of bisecting angle

elongation

what happens when x-ray beam is perpendicular to the long axis of tooth instead of bisecting angle
