Anatomy Monday: Nasolabial Fold (soft tissue)


This week is another soft tissue entity that can be seen on both intraoral and extraoral radiographs. The nasolabial fold presents as a diagonal transition line. A transition line is seen as a defined line where part of the radiograph appears more radiopaque due to superimposition of soft tissue. The nasolabial fold is seen over the maxillary premolar and canine regions.
