What does SLOB stand for in tooth localization?

• A. Same Lingual, Opposite Buccal
• B. Same Occlusal, Opposite Buccal
• C. Superior Lingual, Opposite Buccal
• D. Soft tissue Localization Of Bite

Answer: (A)

Localization uses the parallax effect: two radiographs taken with the X-ray tube shifted relative to the film let you see how a structure moves. SLOB stands for Same Lingual, Opposite Buccal. If the image of a tooth or fragment moves in the same direction as the tube head shift, that object is on the lingual side. If it moves in the opposite direction, it’s on the buccal side. This mnemonic helps you determine the buccolingual position of a structure.
