The various parts of the body are naturaly correlated, this being an essential condition for the formation of an integral unit. The development of this unit is conditioned both by hereditary factors and by environment, which affect it in lesser or greater degree. However, the complicated interation which is naturally difficult to analyse in detail. In the following study of the theoreticcal possibilities to account for the occurrebnce of prognathism. the problem is naturally not approached from the viewpoint of generic development. only theoretical morphological possibilities for the West Mediterrenean Turkish children in the early permanent dentition period selected from the individuals who applied to Suleymaan Demirel University that is the only university for the lake region whose native citizens have been living here for several generations. In our study cephalograms Bjork analysis (1947) were used for evalution of prognatism. 100 children of age 12+/-1, 64 female 36 male were iraced. From these children 43% showed Class 1.34% showed Class II and 23% showed Class III skeletal relation. The difference between the angular values of Bjork study group and our study group was done by one sample test analysis. The association between two quantitative variables was evaluated with Pearsons's correlation coeffcient (rho). Gonial angle, Prognatism angle (ArNPr) and Chin angle (Id Pog Me-Go) showed significant differences between the Sweden tnale population and West Mediterenian Turkish male population standards statistically. (p<0.001, p<0.005, p<0.01 respectively).
