As the buccal object rule states that the buccally located object moves in the direction of the x-ray beam, on changing the direction of x-ray beam, the position of the impacted canine can be determined. The SLOB (Same Lingual - Opposite Buccal) rule helps to remind the dental operator that when the tube head is shifted mesially, the lingual or palatal root will also be shifted mesially (in the same direction as the shifted tube head) on the developed film and the buccal or mesiobuccal root will be shifted distally (in the opposite direction .
