BIROOTED PRIMARY CANINES
A
5-year-old black girl presented for routine dental care. The history and clinical examination findings were within normal limits, however, an intraoral radiographic survey revealed two completely separate roots on each maxillary primary canine. Mandibular canine formation appeared normal, both clinically and radiographically. Reports in the literature of birooted primary canines are exceedingly rare. The probable origin of such teeth is a bilateral ingrowth of tissue flaps from Hertwig’s epithelial root sheath that fuse and form a template for a birooted tooth. One can only speculate as to whether the succedaneous maxillary canines will also demonstrate this abnormality. John R. Kelly.
