occlusal receptorsize 4 in adult size 2 in children
localization techniqueA method used to locate the position of a tooth or object in the jaws, bc the image does not depict the depth or is it is buccal or lingual
buccal object ruleUses 2 images to determine location of object
SLOB ruleS=same L= Lingual O= Opposite B= Buccal
right angle techniqueAcquire one image using periapical technique Acquire 2nd image using occlusal technique
