The purpose of this retrospective study was to evaluate the skeletal and dental maturity according to the vertical facial type and sex in Korean children in the developmental stage. In total, 184 participants aged 8 - 14 years were selected and divided into three groups based on the mandibular plane angle. For the comparison between the sexes, the three groups were each divided into male and female subgroups. The skeletal and dental maturity were assessed using lateral cephalograms, hand-wrist radiographs and panoramic radiographs. The vertical growth group showed significantly greater cervical vertebral and hand-wrist maturity than that in the horizontal growth group. Dental maturity was the highest in the vertical growth group. Girls showed greater skeletal maturity than boys, and no distinct difference was observed between the dental maturity of the sexes. Analysis of the vertical facial type in children can provide ancillary indicators that may help determine the optimal timing for orthodontic treatment initiation. Earlier initiation of orthodontic treatment may be considered for patients with vertical facial growth patterns.

Introduction. The Herbst device is widely used for correction of class II malocclusions; however, most of the researches carried out on the Herbst appliance in literature do not take into account patients with a different mandibular divergence. The aim of this study was to investigate the effects of Herbst on dental and skeletal structures and to evaluate possible influence of vertical facial growth patterns. Methods. A retrospective study was conducted on lateral cephalograms of 75 growing patients (mean age: 9.9 ± 1.9 years) with class II malocclusion treated with Herbst. Subjects were divided into 3 groups using the mandibular divergence index (SN and GoMe angle). Cephalometric parameters were evaluated using the modified SO (sagittal occlusion) Pancherz’s analysis. A statistical analysis was conducted to evaluate differences among groups using ANOVA. Results. Our study showed differences in response to treatment depending on patient’s facial vertical growth pattern. Cranial base angle and mandibular rotation were significantly different (p<0.05) between hypodivergent patients and normodivergent patients and between hypodivergent and hyperdivergent subjects. Conclusion. Hypodivergent patients increased their mandibular divergence during treatment to a greater extent than normodivergents; moreover, hyperdivergent patients exhibited a decreased mandibular divergence at the end of the treatment.

Abstract Objectives This study aimed to compare cranial base angulations in subjects with high-angle, low-angle, and normal-angle vertical growth patterns using cone beam computed tomography (CBCT). Design This study is a retrospective clinical research. Settings This study was carried out at the Dentistry Faculty of Eskisehir Osmangazi University. Participants According to skeletal vertical face growth patterns, 78 subjects (48 females and 30 males, average age: 13.19 ± 1.73 years) were divided equally into three groups: high angle, low angle, and normal angle groups. Main Outcome Measures Cephalometric images were derived from CBCT, and patients were classified according to the SN-GoGn angle (sella-nasion, gonion gnathion angle). Sagittal, axial, and coronal cranial base angulations were measured in three-dimensional (3D) CBCT images. Data were analyzed using the Kolmogorov–Smirnov normality, Kruskal–Wallis, and Mann-Whitney U statistical tests. Results There were statistically significant differences between the low-angle and high-angle groups according to sagittal cranial base angulation parameters (p = 0.01). Conversely, there were no statistically significant differences between vertical facial growth patterns according to coronal and axial cranial angle variables (p > 0.05). Conclusion According to the study results, there were no effects of cranial base angulations in two planes (coronal and axial) on different vertical skeletal growth patterns. In the sagittal cranial base angulation parameter, the high-angle group showed greater angulation values than the low-angle group. CBCT may be helpful for evaluating, diagnosing, and predicting 3D cranial base differences.

Objective To evaluate vertical and sagittal facial growth in children with Apert and Crouzon syndromes and compare it to the growth patterns of a nonsyndromic control group. Design Case-control study. Setting Department of Orthodontics, Children's Hospital Erasmus Medical Centre, Sophia, Rotterdam, The Netherlands. Patients, Participants Sixty-two patients (37 patients with Crouzon syndrome and 25 patients with Apert syndrome) born between 1971 and 2001 (age range 3.9 to 32 years) and 482 nonsyndromic children as a control group. Interventions Lateral cephalograms performed prior to any midfacial surgery of 62 patients and 482 nonsyndromic children were traced and horizontal and vertical measurements were digitized. Main Outcome Measures Cephalometric measurements of SNA, SNB, ANB, NSMe, and SN/palatal plane angles and lower facial height ratio. Results Horizontal measurements for the syndromic groups showed no change in SNA angle during growth. SNA angles were lower in patients with Apert syndrome compared to patients with Crouzon syndrome. The syndromic groups showed smaller values for ANB angles compared to the nonsyndromic group. Vertical measurements showed increased lower facial height ratios for the syndromic groups compared to control subjects. There was an increasing counterclockwise rotation of the palatal plane in relation to the anterior cranial base in syndromic patients. NSMe angles among the three groups were not significantly different. Conclusions Based on the growth differences identified, the sagittal and vertical jaw relationships differ in patients with Crouzon syndrome, patients with Apert syndrome, and control subjects. Syndromic patients show aggravation of midfacial underdevelopment and anterior rotation of the mandible.

The aim of this study was to investigate the relationships between the stages of calcification of various teeth and skeletal maturity stages among Korean subjects. The samples were derived from hand-wrist, panoramic radiographs, and lateral cephalograms of 743 subjects (359 males and 384 females) with ages ranging from 6 to 14 years. Calcification of seven permanent mandibular teeth on the left side were rated according to the system of Demirjian. To evaluate the stage of skeletal maturation, hand-wrist radiographs were analyzed by skeletal maturity indicators (SMI) system of Fishman and lateral cephalograms by cervical vertebral maturation (CVM) method of Baccetti. Statistically significant relationships were found between dental calcification and skeletal maturity stages according to Spearman rank-order correlation coefficients (r = 0.40-0.84, p < 0.001). The second molar showed the highest correlation and central incisor showed the lowest correlation for female and male subjects. For both sexes, canine stage G and second molar stage F were related to SMI 6 and CS 3. Because of the high correlation coefficients, this study suggests that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator of the pubertal growth period in Korean patients.

Mandibular growth pattern (MGP) prediction plays an important role in orthodontic treatment planning. This study sought to assess the mandibular symphyseal width in adolescents with different mandibular growth patterns (MGPs) so as to see whether a correlation exists. This study was conducted on 90 lateral cephalograms of patients aged between 10 and 16 years. The subjects were divided into normo-divergent, hypodivergent and hyperdivergent subgroups based on the gonial angle. The symphyseal measurement included width or depth of the mandibular symphysis according to Akietal study. He suggested that a mandible with anterior growth direction was associated with a large depth of the symphysis. In contrast, a mandible with a posterior growth direction was associated with a small depth of symphysis. To assess the correlation between mandibular symphyseal width and mandibular growth pattern, Pearson’s correlation test was done. Correlation is significant at the 0.01 level (2 tailed). A P-value which is less than 0.05 was considered statistically significant. The mandibular symphyseal width was found to be strongly associated with the MGP. It can be inferred from the results that in vertical growth pattern, as the gonial angle increases, symphyseal width decreases and in horizontal growth pattern, as the gonial angle decreases, symphyseal width increases. Also, in vertical growth pattern subjects, the mandibular symphyseal width is narrower. In contrast, in horizontal growth pattern subjects, the mandibular symphyseal width is wider.

Background The aim of this study was to explore dental maturation as a diagnostic test for skeletal maturation. Materials and Methods Six hundred and fifty-seven growing individuals were classified according to their cervical vertebral maturity and dental maturity, both determined in lateral cephalograms and panoramic radiographs, respectively. The correlation between cervical and dental stages was established for each gender. A receiver operating characteristic curve analysis was made, and sensitivity and specificity values were established. Results Correlation was found between cervical and dental maturation for females (r = 0.73; P < 0.001) and males (r = 0.60; P < 0.001). Sensitivity for dental Stage F, as an indicator of a postmaturation peak stage, was 87.21% for females and 97.1% for males, whereas specificity for the same stage was 82.92% and 72.3% for females and males, respectively. Conclusions Dental maturation evaluation could contribute determining whether a patient is in a pre- or post-growth spurt stage.

Abstract Introduction The facial growth pattern differs from individual to individual, and the variations in it are quite high. The assessment of relationship of dental arch dimensions with the facial growth pattern is essential for proper diagnosis and treatment planning. Aim The purpose of this study was to evaluate and compare the dental and alveolar arch widths in patients with varying facial growth patterns in Distt. Solan population. Materials and Methods Pretreatment lateral cephalograms and dental study models of 45 patients with age group between 16 and 30 years were included in the study. Patients were divided into three groups: group I (normodivergent), group II (hypodivergent), and group III (hyperdivergent) on the basis of y-axis, Jarabak ratio, and SN-MP (Sella-Nasion–mandibular plane) angle. Interpremolar and intermolar dental and alveolar arch widths were measured and compared for all the three groups. Results The results showed that the dental and alveolar arch widths were increased in hypodivergent patients and decreased in hyperdivergent patients, which was not statistically significant. Conclusion It was concluded that the dental and alveolar arch dimensions increased as the facial pattern became horizontal.

Objective. The aim of this study was to compare the profile attractiveness between orthodontic camouflage of the Class III malocclusion and the predictive tracing simulating orthognathic surgery evaluated by dentists and laypeople. Settings and sample population. The sample consisted of 21 patients (9 male; 12 female) with Class III malocclusion treated with orthodontic camouflage and Class III intermaxillary elastics. Material and Methods. The mean initial age of the patients was 24.38 years (SD 3.32), and the mean ANB angle was −1.91° (SD 0.83°). Patients presented skeletal Class III and normal growth patterns. Initial and final lateral cephalograms of each patient were used. The initial cephalogram was used to perform the treatment simulation of orthognathic surgery, and its silhouette was compared to the silhouette obtained from the final cephalogram after Class III orthodontic camouflage. A subjective analysis of profile attractiveness was performed by 47 laypeople and 60 dentists, with scores from 1 (less attractive) to 10 (most attractive). Mann–Whitney tests were used to compare profile attractiveness between the orthodontic treatment and the predictive tracing groups and between dentists and laypeople. Results. The predictive tracing of orthognathic surgery showed to be statistically significantly more attractive (mean score 4.57, SD 2.47) than that of the Class III camouflage orthodontic treatment (mean score 4.22, SD 2.40), with a mean numerical but significant difference of 0.35 (SD 2.01) (P<0.001). Laypeople were more critical than dentists in evaluating profile attractiveness, but numerical difference between the groups was also small. Conclusion. The profile silhouette of predictive tracing simulating orthognathic surgery showed to be more attractive than that of Class III camouflage orthodontic treatment; however, differences were small but statistically significant. Laypeople showed to be more critical than dentists.

Introduction Skeletal maturity is of paramount importance for the diagnosis and prognosis of orthodontic treatment undertaken in adolescents. This can be assessed by different methods. The study here aims at evaluation of the effect of the onset of menarche and body mass index (BMI) percentile, i.e., overall body growth, on the skeletal maturation of adolescent females and, to find the relationship between age at menarche, cervical maturation stages, and BMI percentile in female orthodontic patients of Indian origin. Materials and Methods Adolescent females were asked to fill a questionnaire to extract the history of their menarche and chronological age and those within 3 months of menarche were selected. Their height and weight were measured under standard conditions and BMI was calculated. Lateral cephalograms obtained for them were scaled for cervical vertebrae maturation stages according to Hassel and Farman’s method. These parameters were then statistically correlated. Results The results showed that the girls with higher BMI percentile attained menarche early than their healthier counterparts, whereas attaining menarche did not correlate with any specific stage of skeletal maturity. Conclusion Young girls coming for orthodontic treatment should be carefully assessed for skeletal maturity, as variable amount of skeletal growth may be left even after attaining menarche.
