Sažetak
A discriminant analysis was performed in a sample of 303 children with developmental
disorders (DD) and 303 healthy controls (C) in order to test whether some
oro-dental and physical minor anomalies could discriminate these groups of children.
DD sample comprised 176 mentally retarded (MR) children, 70 children with impaired
hearing (IH) and 57 children with impaired vision (IV). The control group included 303
healthy subjects, matched for sex and age. The analysis comprised seven common oral
and dental anomalies: median diastema, hypodontia, impacted teeth, microdontia,
dens invaginatus, upper lip frenulum and frenulum of the tongue. Minor physical
anomalies were assessed by the method proposed by Waldrop et al., as the average number
of minor anomalies per individual (W1) and as the weighted score of minor anomalies
(W2). Three discriminant functions were obtained by analysis of nine initial variables.
Distinct discrimination and considerable distances were found between the
centroids of the controls and all groups of DD children. The first two discriminant functions
were significant for discrimination between the groups and they explained 98.6%
of the total variance. The first function contained 90.2% of information and was defined
by the number and weighted scores of minor anomalies. The second variable explained
8.4% of the total variability and was defined by three dental anomalies. The results obtained
by the discriminant analysis show that application of dental and minor physical
anomalies enables discrimination between the group of healthy children and the groups
of children with different developmental disorders.
