The buccal object/SLOB rule is the method used to determine the relative positions of two objects in the oral cavity using projectional dental radiography.

Aturan Clark
In 1909, Clark described a radiographic procedure to localize affected teeth to determine their relative antero-posterior position. If both teeth (or, by extension, any two objects, such as teeth and foreign objects) lie ahead of each other relative to the x-ray beam, they will appear superimposed on each other on dental radiography, but it is impossible to know which that is in front of the other. To determine what lies ahead and behind, Clark proposes the SLOB rule , as a collection of three complicated radiographs, but which can be simplified as follows only by using two:
- Open another movie when the x-ray beam has been changed. If an object moves in the same direction as the source of the x-ray beam, it is lingual for another object. If the object is moving in the direction opposite from the source, it is buccal to another object.

In 1952, Richards changed this rule using only 2 radiographs, asserting that the more boldly positioned objects would move more relative to the more palatally or lingually positioned objects.
As a generalization, but not specifically expressed as part of the rules of the buccal Richards object, the more bualal object is (ie the closer to the x-ray source) the larger is moving in the second radiograph when repositioning the source x-ray.
At the University of Alabama School of Dentistry, this rule is called the BAMA rule: b uccal a lways m how oves a .
