Which statement about an apical third root fracture is correct?

• A. It is a medical emergency requiring immediate surgery
• B. Frequently go undetected
• C. It typically presents with marked rotational mobility
• D. It always causes severe pain

Answer: (B)

Apical third root fractures are notoriously hard to detect because the fracture line is near the tip of the root, often with little or no displacement and only mild or absent symptoms. Standard periapical radiographs can fail to reveal the fracture due to superimposition of structures and the small size of the crack. Detecting these fractures often requires repeated radiographs from different angles or, in some cases, 3D imaging like CBCT to visualize the fracture more clearly. Because of this subtle presentation, they frequently go undetected, which is why this statement is the best answer. In contrast, not every apical third root fracture demands immediate surgery; management depends on clinical findings such as vitality, presence of infection, and tooth mobility, and may range from monitoring to stabilization or endodontic therapy. They do not typically cause constant, marked rotational mobility or universal severe pain—both symptoms vary and can be minimal or absent, contributing to the difficulty in detection.
