For a maxillary premolar in a radiograph, the facial root appears distal to the palatal root, the film was exposed with:

Question

Accepted Answer

C. From mesial side of the tooth. If the tube is shifted mesially and the object in question appears to move distally, it lies on the buccal aspect of the reference object. These relationships can be easily remembered by the acronym SLOB: same lingual, opposite buccal. 
Thus,

If the object in question appears to move in the same direction with respect to the reference structures as does the X-ray tube, it is on the lingual aspect of the reference object.
If it appears to move in the opposite direction as the X-ray tube, it is on the buccal aspect.
If it does not move with respect to the reference object, it lies at the same depth (in the same vertical plane) as the reference object.
