“…In this case these dimensions were greater than the average for Japanese children. Table 1 shows the observed crown widths for the patient and the average crown widths of each deciduous tooth of Japanese children [15,16]. Other congenital defects found included two inversely impacted supernumerary teeth in the maxillary midline region.…”

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.

“…On the other hand, no clear groove was noted in the bilateral fused teeth comprising the mandibular primary central and lateral incisors, whereas slight vertical protuberances were observed on the labiolingual sides of the central area of the tooth crown. The observed crown width of each of the patient's teeth is provided in Table 1, and the average crown width of each tooth in Japanese children [16][17][18] is shown in Table 2. The maximum mesiodistal coronal width and faciolingual width were measured in the cast models.…”

Bilateral dental fusion in the primary dentition is a dental anomaly. However, bilateral fusion of maxillary and mandibular primary central and lateral incisors is very rare. The fused teeth were considered to consist of the bilateral upper and lower primary central incisor and lateral incisor. The maxillary primary central and lateral incisors were joined both on the right and left sides of the arch. Bilateral occurrence of unusually large teeth in the lower incisor region was observed. Radiographically, the maxillary fused teeth were observed to have separate coronary parts. The pulp chambers were separate in case of the upper left fused teeth. The other 3 fused teeth were observed to have a single pulp chamber and root canal. The 4 fused teeth in this case did not include any supernumerary teeth.
