Maxillary canine


Another view of the canine region demonstrates the antral ‘Y’ or inverted ‘Y’ formation.This landmark is formed by the intersection of the floor of the nasal cavity and the anterior wall of the maxillary sinus.

The floor of Nasal fossa extends bilaterally away from Anterior Nasal Spine to the apical region of the canine.

The Nasolabial fold marks the anterior border of the thicker soft tissues of the cheek, produces a linear density that courses from the region above the apicies of the canine or lateral incisor to the occlusal plane in the premolar region (visible in some radiographs).
