What is the SLOB rule used for in dental radiology?
Show answer and explanation
Correct answer: A. Identifying which objects are lingual vs. buccal using tube shifting
- A. Correct. SLOB = Same Lingual Opposite Buccal. When two X-rays are taken with the tube shifted horizontally, an object that moves in the SAME direction as the tube shift is LINGUAL; one that moves in the OPPOSITE direction is BUCCAL. Used to locate supernumerary roots, calcified canals, and objects.
- B. Root fractures are diagnosed with specific angulated periapical films, not the SLOB rule.
- C. Vertical bone loss percentage uses radiographic bone height measurements — not the SLOB rule.
- D. Bone density determination uses specific radiographic density values — not the SLOB rule.
