What is another name for the Buccal Object Rule?
|
Tube-shift technique: Clark’s Rule
Slob rule: ( Same Lingual, Opposite buccal) |
|
|
What is the general synopsis of the Buccal Object Rule?
|
Buccal objects appear to move in opposite direction relative to the direction that tube moves.
|
|
|
What is required to apply the buccal object rule?
|
Two films made with slightly different angles or positions.
OR Image of the object from two different angulations |
|
|
What is the exact principal behind the buccal object rule?
|
The principle states: the object closest to the buccal surface will appear to move in the opposite direction relative to the movement of the tubehead when a second film is taken

How do you utilize the Right Angle Technique?
|
•Two radiographs taken at right angles to each other are required. •First radiograph may be a PA or BW -this shows inferior / superior and anterior / posterior position •Second radiograph is a cross-sectional occlusal projection-this reveals facial / lingual and anterior / posterior position
