Congenitally missing maxillary primary canines: report of three cases.

BACKGROUND

Hypodontia is uncommon in the primary dentition and lateral incisors are the most commonly missing primary teeth in the patients affected. Studies have found that hypodontia in the primary dentition involving only maxillary canine is rare.

CASE REPORTS

Three cases of hypodontia in the primary dentition involving only maxillary canine are presented. Two of them were affected by hypodontia and hyperdontia in the permanent dentitions respectively, yet all the permanent canines developed normally in these three cases.

CONCLUSION

In children with congenitally missing maxillary canines, the permanent dentitions may show diverse anomalies in tooth numbers, ranging from hypodontia to hyperdontia.
