Comprehensive dental examinations and panoramic radiographs were used to determine the prevalence of hypodontia in 662 Australian Defence Force recruits. Of the sampled population, 6.3 per cent exhibited some degree of hypodontia (third molar agenesis excluded). Previous studies produced similar results. Third molar agenesis occurred in 22.7 per cent of the sample which again is in agreement with other studies. There was no statistical difference between the sexes in third molar agenesis; however, there was a significant difference with upper second premolars. Females exhibited an extremely low incidence of absence of maxillary lateral incisors.
