[Statistical studies on numerical anomalies of teeth in children using orthopantomograms. Congenital coexistence of hyperdontia and hypodontia].
Statistical studies on numerical anomalies using orthopanthomograms had been attempted. In this paper, congenital coexistence of hyperdontia and hypodontia in individuals had been researched using 4009 orthopanthomograms of pedodontic patients. The tested were following; Male: Age 2-5 1036, 6-11 905, 12-22 Total 1963. Female: Age 2-5 1032, 6-11 985, 12-29 Total 2046. respectively. And 11 (male: 7, female: 4) coexistence cases were found. They were combinations of a hyperdontia (1 tooth: 5, 2 teeth: 2, 3 teeth: 1, 4 teeth: 2, 7 teeth 1) and a hyperdontia (1 tooth or 2 teeth).
