In 1952, Richards amended this rule using only 2 radiographs,Richards AG. The buccal object rule. ''Journal of the Tennessee State Dental Association'' 1953;33:263-268 asserting that the object positioned more buccally will move more relative to the object positioned more palatally or lingually.
As a generalization, but not specifically stated as part of Richards' buccal object rule, the ''more buccal'' an object is (i.e. the closer it is to the x-ray source) the ''more it will move'' in the second radiograph when repositioning the x-ray source.

Clark's Rule
In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be impossible to know which one is in front of the other. To determine which is in front and which is behind, Clark proposed his 'SLOB rule
