Abstract

Congenital deficiency of individual teeth or a group of teeth in the second dentition has been the subject of numerous investigations. Our own research work was aimed at investigating the general incidence of hypodontia in a three-year clinical material (covering 3180 patients) and the numerical incidence of deficiency in individual categories of teeth, the interdependence of hypodontia and sex, the anthropological type, the morphological characteristics of the teeth, the dental arches and the intermaxillary relationships as well as the accompanying orthodontic anomalies have been investigated. The results of these investigations showed:
— that general incidence of hypodontia amounted to 2.32%
— the most frequently missing are the second inferior premolars, the superior lateral incisors, the superior second premolars and the inferior central incisors
— hypodontia is more frequently seen in the upper jaw
— no significant difference was established in the findings of hypodontia between male and female test subjects
— according to the anthropological type the greatest number of test subjects belonged to the brachiocephalic and to the euryprosopic groups
— the size of teeth in patients with hypodontia was smaller on the average than the size of teeth in the control group
— a neutral respectively distal intermaxillary relationship was found in most test subjects
— hypodontia presented an isolated anomaly in only 19 of our test subjects
— compression and prognathism were most frequently found among the accompanying orthodontic anomalies.
