Three populations in South- and North-Thingeyjarsýslas, Northeast Iceland, were surveyed for the presence of torus palatinus. A total of 987 schoolchildren (489 male and 487 female) were examined. A statistically significant difference was noted between the prevalence in South-Thingeyjarsýsla (33.3%) and North-Thingeyjarsýsla (14.6%). Prevalence and size were affected by age and population but not by sex. An association between torus palatinus and torus mandibularis was not found. Secular changes in the occurrence of torus palatinus in Icelanders emphasize the importance of environmental etiological factors and diminish the value of torus palatinus as a racial trait.
对冰岛东北部南丁盖尔耶尔锡拉和北丁盖尔耶尔锡拉的三个人口群体进行了腭隆突存在情况的调查。共检查了987名学童（489名男性和487名女性）。南丁盖尔耶尔锡拉的患病率（33.3%）和北丁盖尔耶尔锡拉的患病率（14.6%）之间存在统计学上的显著差异。患病率和大小受年龄和人口的影响，但不受性别的影响。未发现腭隆突与下颌隆突之间存在关联。冰岛人腭隆突发生率的长期变化强调了环境病因因素的重要性，并降低了腭隆突作为种族特征的价值。
