Transparent Maxillary Cuspid Tooth, Lateral View

Description

Seen in lateral profile, the maxillary canine (cuspid) is isolated in blue against a semi-translucent maxilla, with its crown positioned anterior to the first premolar and posterior to the lateral incisor along the maxillary dental arch. The long single root tapers inferiorly into the alveolar process, with the root apex projecting superiorly toward the floor of the maxillary sinus while remaining separated by a thin plate of maxillary bone. Adjacent teeth, including the incisors, premolars, and molars, sit in their alveoli to provide orientation to the canine’s mesiodistal position and root prominence. For dental anatomy teaching, this view clarifies why the maxillary canine is often described as the corner-stone of the arch: its root length and labial eminence contribute to canine guidance and anterior facial support. Endodontic planning depends on appreciating the canine’s typical single canal morphology and the frequent distal curvature in the apical third, a common source of ledging or instrument separation when working length is misjudged. The proximity of posterior root apices to the maxillary sinus is also contextualized, helping learners distinguish when sinus-related odontogenic symptoms are more plausible for molars and premolars than for the canine. Dental students can use this figure in head and neck anatomy, oral biology, and preclinical endodontics to correlate crown and root form with maxillary bone topography. It also suits textbook spreads on maxillary dentition, patient education materials on root canal therapy, and lectures comparing canine root anatomy to premolars in the context of extraction, implant site planning, and orthodontic space management.
