“…The prevalence of birooted permanent canines in the Japanese population has been reported to be 0·5%[17], 0·32%[18] and 0·29%[19], lower than that reported by Schulze for 1·5–8%[20]. Four cases of bilateral birooted permanent canines have been found [21,22].…”

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.

“…Double-rooted lower canines occasionally occur in humans, however, as witnessed by a number of reports (ALEXANDERSEN, 1963;HARBOROW, 1934;IMOTO et al, 1975;KITAMURA et al, 1981; NAITO, 1961;NAMBA et al, 1969;NOZAKA et al, 1976;ONDA et al, 1988). Although morphological research has been conducted on the teeth of the Japanese macaque, Macaca fuscata (BABA, 1979;SAHEKI, 1966), no data has been reported on the number of canine roots.…”

ABSTRACT. In situ radiographic analysis of the maxillary canines of Macacafuscata was conducted on 88 specimens in 44 individuals (23 dry skulls and 21 live animals) in order to examine the number of roots. The left canines were then extracted from ten female skulls for measurement, further radiographic examination, and visual morphological observation. The results showed a clear sexual dimorphism in root morphology: all male canines were clearly distinguished as single-rooted from the radiograph, whereas more than 40070 of the female canines were double-rooted. Variation was also found among the single-rooted female canines, in that some of these teeth appeared to have a bifurcated canal. This sexual dimorphism in the number of maxillary canine roots and the individual variation found among the females in root and canal morphology are previously unreported for this species. No observations were attempted on mandibular canines, however, because of the incomplete nature of the sample.

Abstract:According to our investigation of lower canines which were extracted from a hundred Indian skulls, we conclude as follows:1) The frequency of double-rooted canines on the right side is 2 per cent, on the left side is 1 per cent and the total is 1.5 per cent.2) The root is bifurcated into a labial and lingual component.Two teeth, one case from the left-side and one from the right, had a bigger labial root. Another tooth, from the right-side, had a bigger lingual root.3) The tooth on the opposite side to the double-rooted one is generally single-rooted.4) The overall length of the double-rooted tooth is shorter and the labiolingual diameter of the crown is longer in comparison with the canine on the opposite side. 5) In comparison with other populations, the frequency of Indians getting double-rooted lower canines is close to those of coloured populations, but less than Whites.
