Answer. Clark’s technique is an intraoral localization technique.

It is also known as buccal object rule or tube shift technique or Clarke’s rule.

Clarke’s Technique Principle

• Relative position of radiographic images of two separate objects changes when the projection angle at which the projection was made is changed.
• A different horizontal angle is used when trying to locate vertically aligned images, e.g. root canals.
• Adifferent vertical angulation is used when trying to locate a horizontally aligned image, e.g. mandibular canal.

Clarke’s Technique Method

• Two radiographs of the object are taken.
• First radiograph is taken using the proper technique and angulations as prescribed.
• Second radiograph is taken keeping all parameters constant and equivalent to those of a first radiograph. Only the direction of central ray is changed whether with a different horizontal or vertical angulation is used.

Clarke’s Technique Interpretation

• When the dental structure or object is seen in the second radiograph, it appears to have moved in the same direction as the shift of the position-indicating device (PID), the structure or the object in question is said to be positioned lingually.

How to apply the SLOB rule

• But if the object appears to move in a direction opposite to the shift of PID, then object in question is said to be positioned buccally.
• It follows the SLOB rule, i.e., Same side lingual and opposite side buccal.
