Abstract
The object of the investigation was to determine the difference in thickness of the soft tissue in subjects with class I and class II/1, by means of horizontal linear variables on laterolateral radiographs, and to determine the differences in the aforementioned variables with regard to sex. Fifty-six laterolateral radiographs of 12-year-old subjects were used for the investigation, out of which 30 with class I (16 boys and 14 girls) and 26 with class II/1 (11 boys and 15 girls). Measurement of the thickness of the soft tissues was performed by means of five horizontal parameters, and the values obtained were statistically analysed by means of Student t-test. Statistical analysis showed that between the sexes in class I the difference existed in landmark A’ and in class II/1 the difference existed in landmark Li. Analysis of boys between classes I and II/1 also showed a difference in landmark A’. Analysis of girls between classes I and II/1 showed a difference in landmark Ls. The total analysis of classes I and II/1, regardless of sex, showed difference in landmarks A’ and Ls.
