Abstract
Purpose of this investigation is verification of socio-economic status o f two orthodontic groups of examinees, to find out differences and similarities between them. Out o f total sample of 640 elementary school age children, 320 are orthognathous (E) and 320 disgnathous (D). The disgnathous subjects have a specific malocclusion; early tooth loss or secondary crowding. According to their sex (male, female), orthodontic condition (E, D) and age (7—14 years) children are classified into 8 groups (each consisting o f 20 examinees). Socio-economic status is assessed by using data on the occupation and education level (high = V, medium = S, low = Z) of the subjects' parents. A specific questionaire is created for the technical performance o f the investigation. The results are statistically analyzed and presented in tables. The data processing is made by using UNIVAC — 1110 computer in FORTRAN system language.
The parents of the ortho gnathous (E) children are mostly o f a higher and high (V) education level as compared to the parents of the disgnathous (D) children who are mostly o f a lower (Z) education level. The ratio is 54,3% E to 44,6% PS. The difference is statistically
significant on the level o f 0,05 (x2 = 6.04, d f = 2). This might indicate that a higher level of parents' education contributes to a more successful influence of parents on the environmental factors which predominantly cause orthodontic anomaly o f a premature tooth loss and secondary crowding.
