Hypohyperodontia in a sample of Chinese population: a retrospective study

Hypohyperdontia prevalence is 0.66%, within the global range (0.002% to 3.1%) with no gender bias. Typically diagnosed in mixed dentition, most cases are bimaxillary involvement. Isolated posterior involvement is rare. ST and agenesis patterns mirror isolated anomalies. Early panoramic screening in suspected cases facilitates timely multidisciplinary management to prevent functional and aesthetic complications.
