All of the following are characteristics of the MAXILLARY CANINE from an occlusal view EXCEPT:

  1. Cingulum
  2. Lingual fossa
  3. Cervical line (CEJ curvature)
  4. Developmental distal groove
Show answer and explanation

Correct answer: D. Developmental distal groove

From the occlusal view, the maxillary canine has a cingulum, lingual fossa, and cervical line. A distal developmental groove is NOT a characteristic occlusal feature of the maxillary canine. The maxillary canine has a single cusp tip, mesial and distal ridges, and a smooth lingual surface with a cingulum. It does NOT have a developmental groove on the distal surface (unlike bicuspids which may have a mesiobuccal developmental groove on the maxillary first premolar).
