Dentistry · Oral anatomy: parotid duct
Sample itemA surgeon identifies the parotid duct after it pierces the buccinator. Where does the duct open into the mouth?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Opposite the upper second molar
Stensen's duct runs across the masseter, pierces buccinator and opens on a small papilla of the cheek opposite the maxillary second molar. Wharton's duct, in contrast, opens at the sublingual caruncle.
Option by option
A. Opposite the lower first molar
This is not the site of the parotid papilla.
B. At the sublingual caruncle
The sublingual caruncle receives the submandibular duct.
C. Beside the upper central incisor
The incisor region does not receive a major duct opening.
D. Opposite the upper second molar (correct)
Correct. The Stensen duct papilla lies opposite the upper second molar.
