Ehlers-Danlos syndrome (classic type): report of a case presenting with an unusual dental anomaly
1Senior Dental Officer, School Dental Care Service, Department of Health, Hong Kong. rony_cho@dh.gov.hk
Abstract:
Ehlers-Danlos syndrome (EDS) comprises a group of generalised connective tissue disorders. Deficiency or alteration of the collagen present in the tissues results in some classic signs such as skin hyper extensibility, joint hypermobility, and vascular fragility. Multiple supernumerary teeth, congenitally missing teeth, and odontogenic keratocysts have been reported in some patients with EDS. To the author's knowledge, transposition of permanent canines has not previously been reported in any case of EDS. This case report presents the dental findings of a sporadic case of classic-type EDS in a 14-year-old Chinese male who had transposition of a permanent maxillary canine as well as the presence of two supernumerary premolars in the mandible.
