title: Hypodontia involving only mandibular permanent canines: report of six cases.
abstract: Agenesis of mandibular permanent canines is uncommon. The occurrence of such an anomaly in patients with all other permanent teeth present, except third molars, is even more rare. The purpose of this case report was to summarize the radiographic findings in 6 Chinese children with hypodontia involving only mandibular permanent canines. The etiology of such an anomaly is not known, but both genetic and environmental factors may play a role.
