Buccal object rule
Buccal Object Rule
The Buccal Object Rule (pronounced: buk-uhl ob-jekt rool) is a principle used in Dental Radiography to determine the relative location of an object in the mouth based on changes in position of the X-ray tube. It is also known as the SLOB rule (Same-Lingual, Opposite-Buccal), an acronym that helps remember the rule's application.
Etymology
The term "Buccal" originates from the Latin word "bucca" which means cheek. In dental terminology, buccal refers to the cheek side of the teeth, as opposed to the tongue (lingual) side. The term "Object Rule" refers to the method used to locate objects, in this case, teeth or dental restorations.
Application
The Buccal Object Rule is applied in the field of Dentistry, specifically in dental radiography. It is used to determine the buccal or lingual position of an object in the mouth when two radiographs are taken at different angles. According to the rule, if the X-ray tube shifts in the same direction as the object, the object is positioned towards the lingual side. If the X-ray tube and the object shift in opposite directions, the object is positioned towards the buccal side.
