Case Report



Hypodontia and hyperdontia are considered to be at opposite ends of the dental development spectrum. Nevertheless, these anomalies may occur concomitantly (hypohyperdontia).

Case report

This clinical report describes two case of hypohyperdontia occurring exclusively in the premaxillary region, and the difficulties associated with its diagnosis and management. Following 24 months of follow-up examinations, Case 1 developed a sequential supernumerary tooth in the tooth 35 region.


Cases of hypohyperdontia can occur exclusively in the premaxillary region and may be difficult to diagnose. Multidisciplinary treatment planning is essential to facilitate appropriate management, and long-term follow-up is necessary as sequential supernumerary teeth may develop.
