title: Occlusion in the primary dentition. Part 2: a comparison of some occlusal traits among pre-school children of the 3 major ethnic groups in Nigeria.
abstract: This paper attempted to compare some of the other occlusal variations in the primary dentition of the children from the 3 major ethnic groups in Nigeria. Cross-sectional epidemiological study involving two major cities in Nigeria. 269, 3-5 year-old children from the 3 major ethnic groups in Nigeria consisting of 125 (46.5%) males and 144 (53.6%) females selected from pre-primary schools/centres. Only children with confirmed ages were included in the study and the criteria of Foster and Hamilton were used in assessing the occlusal features. Although some ethnic differences were observed in relation to the assessed occlusal features, overjet, overbite, cross bite, scissors bite and midline relationship, none was found to be statistically significant (P > 0.05). The occlusal features among the children from the ethnic groups do not differ significantly. Prospective longitudinal study could be worthwhile in further understanding their occlusal developments.
