title: [Evaluation of socio-economic status of the orthognathous and disgnathous school age examinees].
abstract: Purpose of this investigation is verification of socio-economic status of two orthodontic groups of examinees, to find out differences and similarities between them. Out of 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 of 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 questionnaire is created for the technical performance of 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 orthognathous (E) children are mostly of a higher and high (V) education level as compared to the parents of the disgnathous (D) children who are mostly of a lower (Z) education level. The ratio is 54.3% E to 44.6% PS. The difference is statistically significant on the level of 0.05 (x2 = 6.04, df = 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 of a premature tooth loss and secondary crowding.
