Hypodontia is a condition of less teeth than normal complement while when there are more teeth than complement, it is called hyperdontia. The occurrence of hypodontia and hyperdontia in a family is very rare. The purpose of this short communication is to describe the occurrence of numerical variants of hypodontia and hyperdontia in siblings belonging to a family. Studies have indicated genetic factors may influence numerical variations of teeth. A genetic correlation of hypodontia and hyperdontia has been described and suggested for further studies. As with hypodontia, hyperdontia in the primary dentition is rare.
