Oligodontia is a rare condition, and only limited data are available on its prevalence. The present paper is based on data from Danish schoolchildren. When these data are combined with comparable data on Danish schoolchildren published previously by the senior author, it is shown that oligodontia occurs in 0.16% of the children (95% confidence interval, 0.07% to 0.30%). Two of every three congenitally missing teeth were upper or lower second premolars or upper lateral incisors. When data from Danish schoolchildren were combined with population data from similar groups of schoolchildren from the Nordic countries, the condition was found to be more frequent in girls than in boys (P = 0.05).
少牙症是一种罕见的病症，关于其患病率的可用数据有限。本文基于丹麦学龄儿童的数据。当这些数据与资深作者之前发表的关于丹麦学龄儿童的可比数据相结合时，结果显示少牙症在0.16%的儿童中出现（95%置信区间，0.07%至0.30%）。每三颗先天性缺失牙中就有两颗是上颌或下颌第二前磨牙或上颌侧切牙。当将丹麦学龄儿童的数据与来自北欧国家类似学龄儿童群体的人口数据相结合时，发现这种病症在女孩中比在男孩中更常见（P = 0.05）。
