What is a characteristic symptom of osteonecrosis of the jaw (ONJ)?

• A. Gum swelling
• B. Non-healing extraction socket
• C. Excessive tooth mobility
• D. Painful chewing

Answer: (B)

A characteristic symptom of osteonecrosis of the jaw (ONJ) is a non-healing extraction socket. This condition occurs when bone tissue in the jaw dies, often due to disrupted blood supply. In cases of ONJ, after a tooth extraction, the associated socket may fail to heal properly, leading to prolonged exposure of the jaw bone. This symptom is particularly significant because it distinguishes ONJ from other dental complications; while gum swelling, tooth mobility, and painful chewing can be present in various dental conditions, the non-healing socket is a direct indicator of the underlying necrotic bone tissue. Recognition of this specific symptom is crucial for timely diagnosis and management of ONJ.
