To assess the prevalence of some of the occlusal anomalies in Ibadan, Nigeria, an epidemiological survey of 644 secondary school children aged 12-18 years (mean age, 14.73 +/- 1.17 S.D.) was done. The sample consisting of 341(53%) males and 303(47%) females was randomly selected. About 66% were from the middle social class while 34% belonged to the working class. Scissors bite recorded the highest prevalence (6.7%) and cross bite was next with 2.2%. No statistically significant associations were found between the occlusal anomalies and socio-economic class (p > 0.05). No statistically significant gender differences were found in relation to the anomalies (p > 0.05). The prevalences of the occlusal anomalies studied were generally lower than those among northern Nigerian children.
为评估尼日利亚伊巴丹一些咬合异常的患病率，对644名年龄在12 - 18岁（平均年龄14.73 +/- 1.17标准差）的中学生进行了一项流行病学调查。样本由341名（53%）男性和303名（47%）女性组成，是随机选取的。约66%来自中产阶级，34%属于工人阶级。剪刀式咬合的患病率最高（6.7%），其次是反咬合，为2.2%。在咬合异常与社会经济阶层之间未发现统计学上的显著关联（p > 0.05）。在这些异常方面，未发现统计学上的显著性别差异（p > 0.05）。所研究的咬合异常患病率总体低于尼日利亚北部儿童。
