Sample item

After extraction of an upper first molar, a patient reports fluid passing from the mouth into the nose. What complication should be suspected?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Oroantral communication

Maxillary molar roots may lie close to the maxillary sinus, and extraction can create an oroantral communication. It should be assessed and managed to prevent chronic fistula or sinusitis.

Option by option

  • A. Inferior alveolar nerve injury

    Inferior alveolar nerve injury affects mandibular lip and chin sensation.

  • B. Dry socket

    Dry socket causes postoperative pain at the extraction site.

  • C. Sialolithiasis

    Sialolithiasis causes obstruction of a salivary duct, often meal-related swelling.

  • D. Oroantral communication (correct)

    Correct. Oral-to-nasal fluid passage suggests a communication with the antrum.
