title: An epidemiological survey of occlusal anomalies among secondary school children in Ibadan, Nigeria.
abstract: 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.
