title: Bifurcation, birooted primary canines: a case report.
abstract: A rare case of birooted primary canines is reported. A male patient aged 6 years 4 months of age presented with pain and swelling related to the upper right first primary molar. Radiographic examination revealed an incidental finding of bifurcation of the roots of all four primary canines. This represents a rare finding. The prevalence of birooted permanent canines in the Japanese population has been reported, but the prevalence of this abnormality of primary canines in other populations is unknown. This report discusses the findings in the context of the available literature. The possible aetiology, possible inferences for the developing dentition, and the need for careful assessment prior to root canal therapy or extraction are highlighted.
