“…Previous studies also categorized the groups based on the ratio of lower anterior facial height to anterior facial height, which is the Jarabak ratio. 23,24 In the present study, skeletal maturity (CVM) showed a significant positive correlation with the mandibular plane angle (SN-GoMe) in all groups. It can be noted that the maturity of the cervical vertebrae correlates with the mandibular plane angle.…”

The aim of the study is to evaluate skeletal maturity and calcification stages of maxillary canines, in relation to vertical, normal and horizontal facial types in females and males. Material and Method: The sample consisted of 60 patients (30 females and 30 males), with skeletal Class I malocclusion. The subjects were divided into a high-angle group, a low-angle group, and a normal-angle group. Cervical vertebral maturity index (CVM) and Demirjian index (DI) were used to assess the cervical vertebrae maturation level and calcification stages of maxillary canines. Results: CVM stages of the low angle group were found to show a higher tendency for CVM4 in the female group (r=0.484) than in the male group (r=0.439). However, in the high angle group, a higher tendency for CVM6 stage was found in the female group(r=-1.014), and a higher tendency of CVM5 was observed in the male group (r=0.00). The median value of maxillary canine DI stage is stage F in the low-angle and normal-angle groups and G in the high angle group. The DI stages of maxillary canines in the male group are left skewed (r =-1.035), which means that there is a tendency toward low values of maxillary canine DI stages. The DI stages of maxillary canines in the female group are right skewed (r=0.0911), implying that there is a slight tendency toward high values of maxillary canine DI stages. Conclusion:Comparisons between the sexes and facial heights revealed that cervical maturity and tooth calcification stages of maxillary canines are more advanced in females and in the high angle group.

ObjectiveTo evaluate differences in skeletal maturity in relation to vertical facial types and to compare differences in the skeletal maturity of the cervical vertebrae and hand-wrist in females.MethodsThis study included 59 females aged 7 to 9 years with skeletal Class I malocclusion. The participants were categorized into three groups (low, normal, and high) according to the mandibular plane angle. Skeletal maturity was measured using skeletal maturity indicators (SMIs) and the Tanner–Whitehouse III (TW3) method on hand-wrist radiographs and by using cervical vertebrae maturation indicators (CVMIs) on lateral cephalometric radiographs.ResultsThe SMI was higher in the high-angle group than in the low-angle group (p = 0.014). The median TW3 bone age was 11.4 months higher in the high-angle group than in the low-angle group (p = 0.032). There was no significant difference in CVMI among the three groups. Skeletal maturity showed a weakly positive correlation with the mandibular plane angle (SMI, r = 0.391; TW3, r = 0.333; CVMI, r = 0.259).ConclusionsThe skeletal maturity of the hand-wrist in females with a high mandibular plane angle was higher than that in females with a low mandibular plane angle. Obtaining additional hand-wrist radiographs may facilitate evaluation of skeletal maturity of females. In females with a high mandibular angle, the time to commence orthodontic treatment may be earlier than that in females with a low mandibular angle.

“…For the selection of the 100 subjects with different facial patterns, linear (the ratio of ANS-Me/N-Me lower or equal to 56% or higher or equal to 58%) 17,23 and angular (SN-GoGn, NS-Gn, FH-GoMe) cephalometric variables were standardized. 18 The method used in this study for determination of maturation of the permanent teeth was suggested by Demirjian et al 19 because of its simplicity and universal acceptance and is relatively recent compared with other similar methods.…”

“…Angular measurements (Fig. 2) considered to classify the subject either as having a vertical or horizontal growth pattern 18 are the SN-GoGn (angle between anterior cranial base and Steiner's mandibular plane), NS-Gn/Y-AXIS (the angle between the anterior cranial base and line drawn from point S to Gn) and the FH-GoMe/Frankfort-mandibular angle (angle between Frankfort plane and mandibular plane).…”

The purpose of this study was to compare the chronological age with the skeletal age and the dental age in a sample of 100 subjects in the age group of 9 to 12 years with extreme facial patterns to evaluate the growth status of the children. Materials and methods:Lateral cephalograms, panoramic radiographs and hand-wrist radiographs of 100 subjects were taken, and the subjects were classified according to facial growth pattern. The 50 subjects with the greatest predominance of vertical growth and the other 50 with the greatest predominance of horizontal growth were selected; these subjects comprised the vertical and horizontal groups respectively. Comparisons between groups were made with independent t-tests.Results: A statistically significant difference was noted between the dental ages of the vertical and horizontal groups, with the vertical group having a more advanced skeletal and dental age. Conclusion:Subjects with vertical growth pattern should be expected to have earlier dental maturity than horizontal growers.
