“…Likewise, other studies have shown an insignificant difference in onset age between class I and III subjects [ 19 , 20 ]. For instance, Qureshi et al resulted in a similar mean onset age of adolescent growth peak for all subjects of three different classes [ 30 ]. In contrast, few studies have supported the theory of delayed adolescent peak in class III subjects compared to class I [ 18 , 19 ].…”

“…In another study, Qureshi et al concluded that class III boys experience a later onset and also a later termination of the adolescent growth peak. Moreover, it is stated that the shortest and the longest growth peak occurs in class II and class III boys, respectively [ 30 ]. Confirming the findings of above-mentioned studies, Arriola-Guillen et al stated that the adolescent growth spurt occurred one CVM stage earlier in women compared to men [ 32 ].…”

Background Estimating skeletal maturation and growth potential is essential for developing adolescents' best orthodontic treatment plan. The purpose of this study was to compare the duration of adolescent growth peak in subjects of skeletal classes I and III using the cervical vertebral maturation (CVM) method. Methods This retrospective cross-sectional study included 116 Iranian subjects (skeletal class I = 68, skeletal class III = 48) aged 8–16 years old and without previous orthodontic treatments. Using Steiner and Wits analyses, two independent examiners traced pre-treatment lateral cephalograms to determine the subjects' skeletal relationship. The skeletal maturation was then assessed using Baccetti's CVM method. The onset and duration of adolescent growth peak (interval of CS3–CS4) were compared between two skeletal classes and two genders using independent samples t test. Results In skeletal class I and III subjects, the adolescent peak had a mean duration of 1.62 (± 1.33) and 2.00 (± 1.27) years, respectively. The average difference of 0.38 years (4.6 months) between the two groups was statistically significant (p < 0.001). Furthermore, the onset age of adolescent growth peak was 11.91 (± 1.32) and 12.08 (± 1.31) years old in class I and III subjects, respectively. This age difference was not statistically significant (p = 0.630). Males’ adolescent growth peak occurred 1.44 years later (p < 0.001) and lasted 0.20 years less (p < 0.001). Conclusions The adolescent growth peak started at a similar age in class I and III subjects, but the latter experienced the peak for 4.6 months longer. Moreover, females had an earlier and more extended adolescent growth peak.

“…Morphology of the cervical vertebrae, used as an indicator of skeletal development, seems to be influenced by skeletal class in adult patients [58]. A re- cently published study reported skeletal class-and genderrelated differences in skeletal age, although the clinical relevance was rather small [48]. The methods of Demirjian et al and Baccetti et al to determine dental and skeletal age, respectively, are generally accepted, but there are some limitations.…”

Purpose Chronological age often differs from dental and skeletal age. With orthopantomograms and lateral cephalograms, dental and skeletal development can be determined according to the methods published by Demirjian et al. and Baccetti et al. However, gender and skeletal class as possible confounders were frequently not considered and available norm values are not up-to-date. This retrospective cross-sectional study thus aimed to evaluate effects of skeletal class and gender on dental and skeletal age of growing patients and to generate updated norm values for contemporary Central-European patients. Methods A total of 551 patients were included in the dental and 733 in the skeletal age assessment, respectively. Dental analysis was based on tooth mineralisation stages in orthopantomograms (Demirjian) and skeletal age was defined by cervical vertebrae maturation stages (CVMS) in lateral cephalograms (Baccetti). Skeletal class was determined by the individualised ANB angle of Panagiotidis/Witt. With nonlinear regression analysis a formula for determining dental age was established. Effects of gender and skeletal class were evaluated and updated norm values generated. Results Inter- and intrarater reliability tests revealed at least substantial measurement concordance for tooth mineralisation and CVMS. Demirjian stages and CVMS significantly depended on gender with girls developing earlier. Skeletal class significantly affected skeletal age only, but without clinical relevance. Updated norm values for dental age differed significantly from the original values of Demirjian and the values for skeletal age differed from those published by Baccetti. Conclusion Optimised norms, separated by gender, increase precision in determining individual dental and skeletal age during orthodontic treatment planning. Further studies analysing the effect of skeletal class on dental and skeletal development are needed.
