Abstract
The incidence of oral and physical minor anomalies is higher in children with developmental disorders compared with healthy children. The aim of this study was to determine the possibility of discriminating children with developmental disorders from healthy children on the basis of oro-dental and physical minor anomalies. The study was performed on a sample of 303 children with developmental disorders (DD) and a control group of 303 healthy children (HC). The sample of children with developmental disorders comprised 176 mentally retarded children (MR), 70 children with impaired hearing (IH) (partially deaf and deaf), and 57 children with impaired vision (IV) (partially blind and blind). The control group consisted of 303 healthy children of the same age and sex. Multivariate discriminate analysis was performed in the manifest space of 18 oro-dental and physical minor anomalies. The initial space of 18 original variables was reduced to three discriminative functions. Clear discrimination and great distance was determined between the centroids of the control group and the groups of children with developmental disorders. The first two discriminate variables are significant for discrimination between the groups, and they explain 95.7% of the total variance. The first variable contains 87.2% of the information and is defined by oro-dental and toe anomalies. The second variable explains 8.5% of the total variability, and is defined by dental and auricle anomalies. The third function, which is not significant, contains just 4.3% of the total variability. The discriminate functions obtained enable clear discrimination between the three groups of children with developmental disorders, but not clear mutual discrimination of individual entities within the groups of children with developmental disorders.
