This study presents two rare cases of concomitant hypodontia and hyperdontia, a condition involving both missing and extra teeth. A new classification system for this rare dental anomaly is also proposed.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Genetics
Background:
- Concomitant hypodontia and hyperdontia is an extremely rare dental anomaly.
- This condition involves the simultaneous presence of missing teeth (hypodontia) and supernumerary teeth (hyperdontia) in the same individual.
- The prevalence rate ranges from 0.002% to 3.1%.
