The socio-demographic and anthropometric variables could influence the number of teeth present in the child's mouth. To determine the effect of anthropometric and socio-demographic variables on the number of erupted primary teeth, a cross-sectional study was performed involving 1013 children aged between 4 and 36 months who attended the immunization clinics in Ile-Ife, Nigeria. Statistical analyses were performed usingstata. The analyses included frequencies, cross-tabulations, chi squared test and t-test. The number of erupted teeth was modelled as the dependent variable in a multiple regression (Binomial) model, and the socio-demographic (age, gender and socio-economic status) and anthropometric variables, such as weight and height at presentation, as predictor variables. Statistical significance was inferred at P < 0.05. The age and height at presentation had significant association with the number of erupted teeth in this study population (P < 0.001). Also children from high socio-economic class in relation to low socio-economic class had significant larger number of erupted teeth in this study population (P < 0.001). The age and height of the child at presentation were significantly related to the number of erupted teeth. Also children from high socio-economic class had significant lager number of erupted teeth compared with children from low socio-economic class.
