Data on occlusal features and the need for orthodontic treatment in Kenya is scanty. This study was carried out to determine the prevalence of malocclusion in children in Nairobi, Kenya. Nine hundred and nineteen children aged 13-15 years (468 male, 451 female) were examined. The registration method used was that described by Björk et al. The prevalence of malocclusion was 72%. The predominant anteroposterior relationship of the dental arches was neutral occlusion (93%). Specific malocclusion traits were highest for crowding (19%), rotations (19%), posterior crossbite (10%), maxillary overjet (10%), and frontal open bite (8%). There was no statistically significant difference in the overall prevalence of malocclusion between males and females, but some occlusal traits were significantly higher in males. Although the findings indicate that the present population is not characterized by a substantial difference in the overall prevalence of malocclusion compared with other communities, some traits differed in prevalence from those reported elsewhere.
关于肯尼亚咬合特征及正畸治疗需求的数据非常匮乏。本研究旨在确定肯尼亚内罗毕儿童错颌畸形的患病率。对919名13 - 15岁的儿童（468名男性，451名女性）进行了检查。采用的登记方法是比约克等人描述的方法。错颌畸形的患病率为72%。牙弓主要的前后关系为中性咬合（93%）。特定错颌畸形特征中，拥挤（19%）、扭转（19%）、后牙反合（10%）、上颌前突（10%）和前牙开颌（8%）最为常见。男性和女性错颌畸形的总体患病率在统计学上没有显著差异，但某些咬合特征在男性中明显更高。尽管研究结果表明，与其他群体相比，目前该人群在错颌畸形总体患病率上没有实质性差异，但某些特征的患病率与其他地方报道的有所不同。
