angle, gonial angle, FMA angle, NsaNsp -GoGn. Statistical significant differences between cranial base parameters in the two malocclusions groups were depicted, in particular for feminine gender. Regardless of gender, the sphenoidal angle values were mainly increased in both malocclusion groups, when compared to normal population values. The S-Ba lengths were decreased in both malocclusion groups, regardless of gender. More significant alterations of cranial base morphology were depicted in patients with Class II Division 2 malocclusions then in patients with Class II Division 1 malocclusion. The study's results sustain the existence of some cranial base alterations in Class II malocclusions.

In order to verify the concordance of the bone development indices (SMI) estimated on the hand and fist radiograph by the method of Fishman (1982) and the indices of development of the cervical vertebrae (CVMS), estimated on the profile teleradiography by the method of Baccetti (2002), was conducted a cross-sectional study on a group of 150 subjects (89 girls and 61 boys), aged 8-18 years. Based on the existing data in the literature and taking into account the average ages at which the SMI and CVMS stages were reached in the research group, a hypothesis of correspondence between SMI and CVMS stages in the pubertal stages was issued and this hypothesis was statistically verified using the coefficient Cohen k. The obtained results (k = 0.82 for the girls 'group and k = 0.67 for the boys' group) confirm the concordance of the SMI and CVMS indices within the researched group and validate the correspondence hypothesis issued.
