Structures that are superimposed can be separated on the radiograph by shifting the tube-head in the third axis while maintaining the bisecting angle in the plane that includes the axis of the [[Enamel Organ#Root|root]] and the edge (plane) of the film. For example, when making a radiograph of the [[Dental Formula - Dog#Premolars|premolar]] region, the tube-shift redirects the x-ray beam to a [[Dental Terminology|mesial-to-distal or distal-to-mesial]] direction while maintaining the bisecting angle position when viewed from the front of the patient (transverse plane). Shifting the tube [[Dental Terminology|mesially]] (mesiobuccal to distopalatal beam) moves objects that are closer to the tube-head distally on the radiograph image and objects that are closer to the film mesially. <br><br>

Conversely, when the tube-head is shifted distally (distobuccal to mesiopalatal beam), objects that are closer to the tube-head will move mesially on the radiograph, while objects closer to the film will move distally on the radiograph. In other words, objects on the radiograph that move the same direction that the tube was shifted are on the [[Dental Terminology|palatal/lingual]] side, while objects that move the opposite direction from which the tube was shifted are on the [[Dental Terminology|buccal/labial]] side. A helpful acronym to remember this relationship is the '''SLOB rule''', which stands for '''Same Lingual Opposite Buccal'''.
