Treatment plan in contemporary orthodontics cannot be imagine without analyzing soft tissue facial characteristics besides assessment of jaw and dental relationships. Aim. Using a questionnaire, we aimed this study at establishing facial characteristics, in relation to sagittal and vertical facial ratios, which are considered aesthetically acceptable, and which could be altered by the means orthodontic treatment. Material and Method. The research was conducted in persons from 23 to 30 years of age whose photographs were taken in standard conditions. Photographs of three patients with different facial profiles were chosen (Class I, Class II and Class III). Every photo was modified in six new profiles by changing facial features. This included mesial and distal shift of maxilla and mandible, as well as increase and decrease of lower facial height. Results. The results showed that straight profile, which is most often present in normal jaw relationships, is considered the most beautiful, furthermore slightly convex profiles are also considered very attractive. Convex profile is connected with distal jaw relationship and its intensity affects facial attractiveness. Concave profile in patients with mesial jaw relationship is aesthetically the least acceptable.

The aim of this study was to examine the efects of Delair`s mask on facial skeleton in patients with Class III antero-posterior jaw relationship. Two groups of children were evaluated. The first group of 34 children with Class III was treated with Delair`s mask. The second group of 46 children with Class III did not receive any orthodontic treatment and was presented as a control group. In the first group pretreatment and post treatment radiographic tracing was done while second tracing in the control group was done a year after diagnostic radiographic tracing. Analysis of the skeletal facial profile was done measuring SNA, SNB and ANB angles. Rotation of the maxillary base (NS/SpP), rotation of the mandibular base (NS/MP) and vertical relationship between jaws (SpP/MP) were also measured. The results were statisticaly analysed using T test, descriptive statistics and Wilcoxon`s test. The results of this study showed changes in facial skeleton in children treated with Delair`s mask compared to the control group. In the first group of children SNA and ANB angles were increased and the SNB angle was decreased.

The aim of this investigation was to assess the craniofacial morphology of five male individuals with 46,XX chromosomal constitution, and to compare them with normal male individuals (46,XY) and normal female participates (46,XX). The investigation was carried out on the lateral cephalomestic radiographs of five male individuals with sex reverse syndrome (46,XX chromosomal constitution), 62 normal female (46,XX) and 31 normal male (46,XY chromosomal constitution) participants. The following angular variables were measured: SNA, SNB, ANB, SN/SpP, SN/MP and SpP/MP. For each variable the mean value and standard deviation were calculated. The Student t-test was used to compare the result obtained between the group of patients with sex reverse syndrome and group of normal male, as well as of normal female participants. The male individuals with 46, XX chromosomal constitution showed slight bimaxillary retrognathism, and class III sagittal jaw relationship. Due to decreased inclination of the upper jaw to the anterior cranial base, the angle of vertical jaw relationship slightly increased in the group of patients with sex reverse syndrome, compared to normal male and female participants.
