Where is the parotid duct located?

The parotid duct, also known as Stensen's duct, is located in relation to the parotid salivary gland, which is situated in the region of the cheeks. The duct emerges from the anterior part of the gland and runs forward to open into the oral cavity at the vestibule opposite the second upper molar tooth.

Understanding the anatomical position of the parotid duct is essential for dental professionals. For instance, it is key in procedures involving salivary flow or in the management of conditions affecting the parotid gland. The duct is specifically positioned mesial (toward the midline) to the parotid gland as it extends anteriorly.

In contrast, the other options that suggest distal, posterior, or superior locations do not accurately describe the pathway and orientation of the parotid duct relative to the gland itself. This precise anatomical knowledge aids in clinical assessments and interventions in dental hygiene and oral health management.
